Surface Acoustic Wave (SAW) and Bulk Acoustic Wave (BAW) duplexers of assessed quality - Part 2: Guidelines for the use

IEC 62604-2:2011 concerns the duplexers, which can separate receiving signal from transmitting signal and are key components for two-way radio communications. They are generally used in mobile phones using CDMA systems such as N-CDMA, W-CDMA / Universal Mobile Telecommunication System (UMTS). So far, dielectric duplexers have been mainly used. However, recently SAW duplexers, which are utilized surface acoustic wave (SAW), are becoming popular and replacing the dielectric duplexers year by year in recent mobile phones, because of their advantage of small size, light weight and good electrical performances. In addition to SAW duplexers, BAW duplexers, which are utilized bulk acoustic wave (BAW), are also becoming in the spotlight and popular because of their higher Q property and better performances especially in PCS band. 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.

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

La CEI 62604-2:2011 concerne les duplexeurs qui peuvent séparer les signaux en réception des signaux en émission et qui sont des composants essentiels pour les radiocommunications bilatérales. Ils sont généralement utilisés dans les téléphones mobiles qui utilisent les systèmes CDMA comme les systèmes N-CDMA, W-CDMA / Universal Mobile Telecommunication System (UMTS). Jusqu'à présent, les duplexeurs diélectriques étaient majoritairement utilisés. Toutefois, au cours de la période récente, les duplexeurs OAS qui utilisent des ondes acoustiques de surface (OAS) se répandent et au fil des années ils remplacent les duplexeurs diélectriques dans les téléphones mobiles récents car ils présentent les avantages suivants: petites dimensions, faible poids et bonnes performances électriques. A côté des duplexeurs OAS, les duplexeurs OAV qui utilisent les ondes acoustiques de volume (OAV) sont de plus en plus connus et appréciés en raison de leur propriété Q plus élevée et de leurs meilleures performances en particulier dans la bande PCS. Les présentes lignes directrices ne sont pas destinées à expliquer la théorie de ces duplexeurs ni à couvrir toutes les situations qui peuvent apparaître dans la pratique. Elles attirent l'attention sur certains des aspects les plus importants qu'il convient qu'un utilisateur prenne en compte avant de passer commande pour des duplexeurs OAS et OAV pour une nouvelle application. Ainsi, l'utilisateur évitera d'être confronté à des performances non satisfaisantes. Dans la mesure où les duplexeurs OAS et les duplexeurs OAV présentent des performances très similaires dans leur utilisation, il est utile et pratique pour les utilisateurs que les deux types soient décrits dans une seule norme.

Radiofrekvenčni dupleksorji (SAW) in visokofrekvenčni dupleksorji (BAW) - 2. del: Navodilo za uporabo

Ta del standarda IEC 62604 zadeva dupleksorje, ki lahko ločijo sprejeti signal od oddanega signala in so ključni sestavni deli za dvosmerno radijsko komunikacijo. Na splošno se uporabljajo v mobilnih telefonih s sistemi CDMA, kot so N-CDMA, W-CDMA/univerzalni telekomunikacijski mobilni sistem (UMTS). Do sedaj so se v glavnem uporabljali dielektrični dupleksorji. Vendar v zadnjem času vse popularnejši postajajo radiofrekvenčni dupleksorji (SAW), ki zaradi svoje majhnosti, lahkosti in dobrih električnih zmogljivosti zamenjujejo dielektrične dupleksorje v novejših mobilnih telefonih. Poleg radiofrekvenčnih dupleksorjev so vse bolj priljubljeni visokofrekvenčni dupleksorji (BAW) zaradi svojih višjih lastnosti Q in boljših zmogljivosti, zlasti v pasu PCS. 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 zlasti velja za izbiro običajne 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.

NOTE In this standard, SAW and BAW duplexers are treated simultaneously because both duplexers are used in

the same manner especially in mobile phones and have same requirements of characteristics, test method and so

on.

SURFACE ACOUSTIC WAVE (SAW) AND
BULK ACOUSTIC WAVE (BAW) DUPLEXERS
OF ASSESSED QUALITY –
Part 2: Guidelines for the use
1 Scope

This part of IEC 62604 concerns the duplexers, which can separate receiving signal from

transmitting signal and are key components for two-way radio communications. They are

generally used in mobile phones using CDMA systems such as N-CDMA, W-CDMA /

Universal Mobile Telecommunication System (UMTS). So far, dielectric duplexers have been

mainly used. However, recently SAW duplexers, which are utilized surface acoustic wave

(SAW), are becoming popular and replacing the dielectric duplexers year by year in recent

mobile phones, because of their advantage of small size, light weight and good electrical

performances. In addition to SAW duplexers, BAW duplexers, which are utilized bulk acoustic

wave (BAW), are also becoming in the spotlight and popular because of their higher Q

property and better performances especially in PCS band.

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

of transmitting and receiving filters and isolation level between transmitting and receiving

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 normal frequency.

3 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 mobile phones 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 transmitting and receiving ports. Since the SAW and BAW duplexer is

used in RF front-end of the mobile phones, lower insertion attenuation, higher

isolation/rejection level, stronger power durability and smaller/thinner package dimension are

strictly required.
4 Fundamentals of SAW and BAW duplexers
4.1 Basic function

Duplexers are necessary for mobile phones to simultaneously receive and transmit signal.

Duplexers are 3-port devices which consist of Antenna port, Transmitter port (TX port) and

Receiver port (RX port) shown in Figure 1. It has three basic functions. First one is to transmit

transmitting signal from TX port to Antenna port. Second one is to transmit receiving signal

from Antenna port to RX port. Last one is to prevent from leaking transmitting signal from TX

port to RX port. The transmitting frequency and the receiving frequency are determined

corresponding to each mobile phone system. For example, Table 1 shows typical allocated

frequency bands for UMTS.
