Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) duplexers of assessed quality - Part 2: Guidelines for the use (IEC 62604-2:2017)
This part of IEC 62604 concerns duplexers which can separate receiving signals from
transmitting signals and are key components for two-way radio communications, and which
are generally used in mobile phone systems compliant with CDMA systems such as N-CDMA
in second generation mobile telecommunication systems (2G), W-CDMA / UMTS (3G) or
LTE (4G). While in 2G systems mainly dielectric duplexers have been used, the ongoing
miniaturization in 3G and 4G mobile communication systems promoted the development and
application of acoustic wave duplexers due to their small size, light weight and good electrical
performance. While standard surface acoustic wave (SAW) duplexers have been employed for
applications with moderate requirements regarding the steepness of individual filters,
applications with narrow duplex gap (e.g. Bands 2, 3, 8, 25), i.e. the frequency gap between
receiving and transmitting bands, require the application of temperature-compensated (TC)
SAW or bulk acoustic wave (BAW) technology, because of their better temperature
characteristics and resonator Q-factors.
It is neither the aim of these guidelines to explain theory, nor to attempt to cover all the
eventualities which may arise in practical circumstances. These guidelines draw attention to
some of the more fundamental questions, which should be considered by the user before he
places an order for SAW and BAW duplexers for a new application. Such a procedure will be
the user’s insurance against unsatisfactory performance. Because SAW and BAW duplexers
have very similar performance for the usage, it is useful and convenient for users that both
duplexers are described in one standard.
Standard specifications, such as those of IEC, of which these guidelines form a part, and
national specifications or detail specifications issued by manufacturers will define the
available combinations of centre frequency, pass bandwidth and insertion attenuation for each
sort of transmitting and receiving filters and the isolation level between transmitter and
receiver ports, etc. These specifications are compiled to include a wide range of SAW and
BAW duplexers with standardized performances. It cannot be over-emphasized that the user
should, wherever possible, select his duplexers from these specifications, when available,
even if it may lead to making small modifications to his circuit to enable the use of standard
duplexers. This applies particularly to the selection of the nominal frequency band.

Duplexeurs à ondes acoustiques de surface (OAS) et à ondes acoustiques de volume (OAV) sous assurance de la qualité - Partie 2: Lignes directrices d'utilisation (IEC 62604-2:2017)
L’IEC 62604-2:2017 concerne les duplexeurs qui peuvent séparer les signaux en réception des signaux en émission et constituent des composants essentiels pour les radiocommunications bilatérales. Ils sont généralement utilisés dans les systèmes de téléphonie mobile conformes aux systèmes CDMA comme les systèmes N-CDMA des systèmes de télécommunication mobile de seconde génération (2G), W-CDMA / UMTS (3G) ou LTE (4G).
Cette édition comprend les modifications techniques majeures suivantes par rapport à l’édition précédente:
- description des diplexeurs;
- prise en compte des duplexeurs avec un accès RX symétrique dans le paragraphe relatif à la méthode de mesure (7.3).
NOTE Dans la présente Norme, les duplexeurs à OAS et à OAV sont traités simultanément car ils sont utilisés de la même façon, en particulier dans les systèmes de téléphonie mobile, et présentent les mêmes exigences quant à leurs caractéristiques, leur méthode d’essai, etc.
Radiofrekvenčni (SAW) in visokofrekvenčni (BAW) duplekserji ocenjene kakovosti - 2. del: Smernice za uporabo (IEC 62604-2:2017)
Ta del standarda IEC 62604 zadeva dupleksorje, ki lahko ločijo sprejete signale od oddanih signalov in so ključni sestavni deli za dvosmerno radijsko komunikacijo ter se običajno uporabljajo v sistemih mobilnih telefonov, ki so skladni s sistemi CDMA, kot je N-CDMA v telekomunikacijskih mobilnih sistemih druge generacije (2G), W-CDMA / UMTS (3G) ali LTE (4G). Medtem ko se v sistemih 2G uporabljajo predvsem dielektrični dupleksorji, je tekoča miniaturizacija v mobilnih komunikacijskih sistemih 3G in 4G spodbudila razvoj in uporabo zvočnovalovnih dupleksorjev zaradi njihove majhnosti, lahkotnosti in dobre električne zmogljivosti. Standardni površinski zvočnovalovni (SAW) dupleksorji pa so se uporabljali za aplikacije z zmernimi zahtevami glede strmine posameznih filtrov, uporabe z ozko dupleksno vrzeljo (na primer, pasovi 2, 3, 8, 25), tj. frekvenčna vrzel med oddajnimi in sprejemnimi pasovi zahteva uporabo temperaturno kompenzirane tehnologije zvočnih valov (SAW) ali visokofrekvenčnih valov (BAW), zaradi boljših temperaturnih značilnosti in faktorjev Q resonatorja.
Cilj teh smernic ni pojasniti teorijo, niti poskusiti zajeti vse morebitne primere, do katerih lahko pride v praktičnih okoliščinah. Te smernice pozornost usmerjajo v nekatera bolj temeljna vprašanja, o katerih bi moral razmisliti uporabnik, preden se odloči za radiofrekvenčne ali visokofrekvenčne dupleksorje za novo aplikacijo. S tem se bo zavaroval pred nezadovoljivimi zmogljivostmi. Ker imajo radiofrekvenčni in visokofrekvenčni dupleksorji zelo podobne zmogljivosti za uporabo, je koristno in priročno za uporabnike, da sta oba dupleksorja opisana v enem standardu.
Standardne specifikacije, kot so specifikacije IEC, katerih del so tudi te smernice, in nacionalne specifikacije ali podrobne specifikacije, ki so jih izdali proizvajalci, opredeljujejo razpoložljive kombinacije srednje frekvence, pasovne širine za prepuščanje in vklopne izgube za vsak oddajni in sprejemni filter ter raven izolacije med oddajnimi in sprejemnimi vrati itd. Te specifikacije so sestavljene tako, da vključujejo širok obseg radiofrekvenčnih in visokofrekvenčnih dupleksorjev s standardiziranimi zmogljivostmi. Zelo pomembno je, da uporabnik, kadar je le mogoče, svoje dupleksorje izbere med temi specifikacijami, če so na voljo, čeprav bo zato moral nekoliko spremeniti tokokrog, da bo omogočil uporabo standardnih dupleksorjev. To velja zlasti za izbiro nazivne frekvence.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 62604-2 has been prepared by IEC technical committee 49:
Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
control, selection and detection.
This second edition cancels and replaces the first edition published in 2011. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• diplexers are described;
• duplexers with a balanced RX port are considered in the measurement method subclause
(7.3).

4 Technical considerations
It is of prime interest to a user that the duplexer characteristics should satisfy particular
specifications. The selection of the front-end circuits in user equipments and SAW and BAW
duplexers to meet such specifications should be a matter of agreement between the user and
the manufacturer.
Duplexer characteristics are usually expressed in terms of centre frequency, pass bandwidth
and insertion attenuation for each of transmitting and receiving filter parts in the duplexer and
isolation level between the transmitter and receiver ports. Since the SAW and BAW duplexer
is used in RF front-end of the user equipments, lower insertion attenuation, higher
isolation/rejection level, stronger power durability and smaller/thinner package dimensions are
strictly required.
5 Fundamentals of SAW and BAW duplexers
5.1 Basic function
5.1.1 General
Duplexers are necessary for frequency division duplex (FDD) equipments to receive and
transmit signals simultaneously. Duplexers are 3-port devices which consist of an antenna
port, a transmitter port (TX port) and a receiver port (RX port), as shown in Figure 1. The
duplexer has three basic functions;
– to transfer the transmitting signal from the TX port to the antenna port;
– to transfer the receiving signal from the antenna port to the RX port;
– to prevent transfer of the transmitting signal and noise from the TX port to the RX port.
The transmitting and the receiving frequencies are determined corresponding to each mobile
communication system. For example, Table 1 shows typical allocated frequency bands for
UMTS.

5.2 Basic structure
Duplexers are 3-port devices/modules, which enable to transmit and receive signals
simultaneously through a common antenna. A basic structure of duplexers is shown in
Figure 5. SAW and BAW duplexers consist of a transmitter (TX) part and a receiver (RX) part.
These two parts, which may add a phase shifter, are connected to an antenna port. The
phase shifter is utilized to prevent the interaction between the filters. In Figure 5, Z and Z
t r
correspond to the impedance of the TX and RX part at the antenna port side, whereas Z is
o
the impedance of the antenna port. The following conditions shall be fulfilled to achieve the
duplexer functions.

5.3 Principle of operation
In the TX pass band, the impedance of the TX part in the antenna port side (Z ) is almost the
t
same as that of antenna(Z ), while that of the RX part (Z ) is much higher, which means that
o r
at the antenna port, the RX part has large reflection coefficient in this band.

On the other hand, in the RX pass band, the impedance of the RX part at the antenna port
side (Z ) is almost the same as that of antenna (Z ), while that of the TX part (Z ) is much

Figure 5 – The block diagram of a duplexer
The transmitting signal applied to the TX port passes through the TX filter and then flows to
the antenna port, not the RX filter. The received signal from the antenna port does not flow to
the TX filter, but to the RX filter. As a result, the TX part and the RX part can share the
common antenna port. In the following explanation, the impedance of the antenna (Z ) is
o
assumed to be 50 Ω. The S curve of the TX part at the antenna port side shall satisfy the
11
demanded condition indicated in Figure 6. The impedance of its pass band shall be around
50 Ω. In the rejection band, the impedance shall be sufficiently larger than 50 Ω. In the actual
duplexer, the S trace in the Smith chart of the TX filter is rotated to its optimum state by a
11
phase shifter, as shown in Figure 7. On the other hand, the frequency characteristics of the
amplitude of S remains the same as that without phase shifter. Figure 8 shows the S
21 21
frequency characteristics and S demanded condition of the RX part.

56 FOREWORD
57 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
58 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
59 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
60 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
61 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
62 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
63 in the subject dealt with may participate in this preparatory work. International, governmental and non-
64 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
65 with the International Organization for Standardization (ISO) in accordance with conditions determined by
66 agreement between the two organizations.
67 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
68 consensus of opinion on the relevant subjects since each technical committee has representation from all
69 interested IEC National Committees.
70 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
71 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
72 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
73 misinterpretation by any end user.
74 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
75 transparently to the maximum extent possible in their national and regional publications. Any divergence
76 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
77 the latter.
78 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
79 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
80 services carried out by independent certification bodies.
81 6) All users should ensure that they have the latest edition of this publication.
82 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
83 members of its technical committees and IEC National Committees for any personal injury, property damage or
84 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
85 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
86 Publications.
87 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
88 indispensable for the correct application of this publication.
89 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
90 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
91 International Standard IEC 62604-2 has been prepared by IEC technical committee 49:
92 Piezoelectric, dielectric and electrostatic devices and associated materials for frequency
93 control, selection and detection.
94 NOTE:In this standard, SAW and BAW duplexers are treated simultaneously because both duplexers are used in
95 the same manner especially in mobile phone systems and have same requirements of characteristics, test method
96 and so on.
97 This second edition cancels and replaces the first edition published in 2011. This edition
98 constitutes a technical revision.
99 This edition includes the following significant technical changes with respect to the previous
100 edition:
101 • Diplexer is described;
102 • Duplexer with balanced RX port is considered at the measurement method subclause.

126 1 Scope
127 This part of IEC 62604 concerns the duplexers, which can separate receiving signal from
128 transmitting signal and are key components for two-way radio communications, are generally
129 used in mobile phone sysytems compliant with CDMA systems such as N-CDMA in 2nd
130 generation mobile telecommunication systems (2G), W-CDMA / UMTS (3G) or LTE (4G).
131 While in 2G systems mainly dielectric duplexers have been used, the ongoing miniaturization
132 in 3G and 4G mobile communication systems promoted the development and application of
133 acoustic wave duplexers due to their small size, light weight and good electrical performance.
134 While for applications with moderate requirements regarding the individual filters’ steepness,
135 standard surface acoustic wave (SAW) duplexers have been employed, applications with
136 narrow duplex gap (e.g. Bands 2, 3, 8, 25), i.e. the frequency gap between receiving and
137 transmitting bands, require the application of temperature-compensated (TC) SAW or bulk
138 acoustic wave (BAW) technology because of their better temperature characteristics and
139 resonator Q-factors.
140 It is neither the aim of these guidelines to explain theory, nor to attempt to cover all the
141 eventualities which may arise in practical circumstances. These guidelines draw attention to
142 some of the more fundamental questions, which should be considered by the user before he
143 places an order for SAW and BAW duplexers for a new application. Such a procedure will be
144 the user’s insurance against unsatisfactory performance. Because SAW and BAW duplexers
145 have very similar performance for the usage, it is useful and convenient for users that both
146 duplexers are described in one standard.
147 Standard specifications, such as those of IEC of which these guidelines form a part, and
148 national specifications or detail specifications issued by manufacturers, will define the
149 available combinations of centre frequency, pass bandwidth and insertion attenuation for each
150 of transmitting and receiving filters and isolation level between transmitter and receiver ports,
151 etc. These specifications are compiled to include a wide range of SAW and BAW duplexers
152 with standardized performances. It cannot be over-emphasized that the user should, wherever
153 possible, select his duplexers from these specifications, when available, even if it may lead to
154 making small modifications to his circuit to enable the use of standard duplexers. This applies
155 particularly to the selection of the nominal frequency band.

165 3 Technical considerations
166 It is of prime interest to a user that the duplexer characteristics should satisfy particular
167 specifications. The selection of the front-end circuits in user equipments and SAW and BAW
168 duplexers to meet such specifications should be a matter of agreement between the user and
169 the manufacturer.
170 Duplexer characteristics are usually expressed in terms of centre frequency, pass bandwidth
171 and insertion attenuation for each of transmitting and receiving filter parts in the duplexer and
172 isolation level between transmitter and receiver ports. Since the SAW and BAW duplexer is
173 used in RF front-end of the user equipments, lower insertion attenuation, higher
174 isolation/rejection level, stronger power durability and smaller/thinner package dimensions are
175 strictly required.
176 4 Fundamentals of SAW and BAW duplexers
177 4.1 Basic function
178 Duplexers are necessary for user equipments to receive and transmit signals simultaneously.
179 Duplexers are 3-port devices which consist of Antenna port, Transmitter port (TX port) and
180 Receiver port (RX port) shown in Figure 1. It has three basic functions. First one is to transfer
181 transmitting signal from the TX port to the Antenna port. Second one is to transfer receiving
182 signal from the Antenna port to the RX port. Last one is to prevent the transmitting signal and
183 noise from the TX port to the RX port. The transmitting and the receiving frequencies are
184 determined corresponding to each mobile communication system. For example, Table 1
185 shows typical allocated frequency bands for UMTS.
