标准范围

IEC？62604-2:20 17(E)涉及双工器，其可以将接收信号与发送信号分离并且是双向无线电通信的关键部件，并且其通常用于与CDMA系统兼容的移动电话系统中，例如第二代移动电信系统(2G)中的N-CDMA、W-CDMA/UMTS(3G)或LTE？（4G）。第二版取消并取代了2011年出版的第一版。此版本构成技术修订。？与上一版相比，此版本包括以下重大技术变更:-描述了双工器；-在测量方法子条款（7.3）中考虑了具有平衡RX端口的双工器。笔记？在本标准中，SAW和BAW双工器被同时处理，因为这两种双工器以相同的方式使用，特别是在移动电话系统中，并且具有相同的特性、测试方法等要求。

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 LTE？(4G).
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).
NOTE？ 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.
