Description

IEC 62604-2:2017(E) 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 LTEA (4G).
This second edition cancels and replaces the first edition published in 2011. This edition constitutes a technical revision.A 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).
NOTEA In this standard, SAW and BAW duplexers are treated simultaneously because both duplexers are used in the same manner especially in mobile phone systems and have same requirements of characteristics, test method and so on.
