Description

通信电路及通信设备
本申请要求在2019年09月19日提交中国专利局、申请号为201910888490.6的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，例如，涉及一种通信电路及通信设备。
背景技术
第五代移动通信系统新无线(the 5th Generation mobile communication system New Radio，5G NR)有两种工作模式，一种是不需要4G辅助的独立组网(StandAlone，SA)模式，另一种是需要4G做信令辅助的非独立组网(non-SA)模式。无论哪种模式，在移动终端上，3G、4G都是标准配置，因此，5G终端必然涉及与3G、4G乃至尚未完全淘汰的2G共存的问题。根据第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)提出的频段规划，5G包含sub 6G和毫米波两种频谱资源。其中，sub 6G分布6GHz以下，出于节省资金、频谱复用的考虑，一些运营商打算将长期演进(Long Term Evolution，LTE)和5G合用频谱资源。譬如LTE频带(Band)41和5G N41就是合用2496～2690MHz的频谱。而芯片方案厂家推出的5G模块，和4G是相对独立的，需要增加较多的电路和天线以同时支持4G、5G两种制式。
4G、5G电路相互独立，对于寸土寸金的移动终端来说会占用较多的额外电路面积，而且当4G、5G天线分别支持4x4多入多出(Multiple-Input Multiple-Output，MIMO)时，手机上天线数量众多。相关技术中，通过共用部分天线，减少了终端上的天线数量，从而简化了终端上的天线布局布线。但是，单靠滤波器进行天线合路，对于路径的损耗是很大的。
