Surface acoustic wave (SAW) and bulk acoustic wave (BAW) duplexers of assessed quality - Part 2: Guidelines for the use (IEC 62604-2:2022)
IEC 62604-2:2022 is available as IEC 62604-2:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 62604-2:2022 applies to 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). These guidelines draw attention to some fundamental questions about the theory of SAW and BAW duplexers and how to use them, which will 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. This edition includes the following significant technical changes with respect to the previous edition:
- the term "cross-isolation" has been added to Clause 3;
- multiplexers are described.
NOTE In this document, SAW and BAW duplexers are treated simultaneously because both duplexers are used in the same manner, especially in mobile phone systems and have the same requirements of characteristics, test method and so on.

IEC 62604-2:2022 est disponible sous forme de IEC 62604-2:2022 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.
L’IEC 62604-2:2022 s’applique aux 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 d’accès multiple par répartition en code (AMRC) comme les systèmes N-CDMA des systèmes de télécommunication mobile de seconde génération (2G), les systèmes W-CDMA/UMTS (3G) ou les systèmes LTE (4G). Les présentes lignes directrices attirent l’attention sur certaines des questions fondamentales concernant la théorie des duplexeurs à OAS et à OAV, et leurs modalités d’utilisation, qui sont à prendre en considération par l’utilisateur avant de commander un duplexeur à OAS ou à OAV pour une nouvelle application. Ainsi, l’utilisateur évite d’être confronté à des performances non satisfaisantes. Dans la mesure où les duplexeurs à OAS et à 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. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
- ajout du terme "isolation de polarisation croisée" à l’Article 3;
- description des multiplexeurs.

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, go
