1 Scope
This part of IEC 62604 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.
