本申请主张在2019年1月24日在中国提交的中国专利申请No.201910067093.2的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种信号收发装置及终端设备。
背景技术
随着经济技术发展和科学技术的不断进步，用户对移动通信技术提出了越来越多的需求，如高可靠性和低时延，以满足车联网、自动驾驶和远程医疗等应用要求；更高的通信速率，以支持超清视频的应用需求；低功耗、大连接场景和高流量密度等，以满足智能工业和农业等在物联网和热点地区覆盖的需求。为满足这些需求，第五代移动通信技术(简称5G)，应运而生，5G通过引入新的宽带频谱，如毫米波频段、6G以下频段(简称sub 6G)划分出3.5GHz(3.3GHz-4.2GHz)和4.5GHz(范围为4.4GHz-5.0GHz)的频段实现宽带的高速和低时延覆盖要求，同时还采用大规模天线技术和多址接入、波束赋形、高功率终端等技术满足上述需求。目前的5G频谱规划如下：
Figure PCTCN2020073793-appb-000001
Figure PCTCN2020073793-appb-000002
由上述列表可以看出，5G新增的sub 6G频段，即n77、n78、n79频段均为TDD(Time Division Duplexing，时分双工)，因此TDD在5G中占比会上升，其应用将会受到更多的重视。另外，n1、n2、n3、n5、n7、n8、n38、n41等频段，都是LTE(Long Term Evolution，长期演进)的refarming(频谱重整)频段，因此4G和5G在很长的一段时间内将长期共存，终端产品的发展趋势是轻量化和便携化，4G和5G的长期共存会导致终端产品的PCB(Printed Circuit Board，印制电路板)面积增大，产品重量增加，因此减小终端产品体积和重量是当前的一大挑战。而4G和5G的长期共存以及5G的大规模接入和高功率终端技术，会有1路发射4路接收(简称1T4R)和2路发射4路接收(简称2T4R)场景存在，使得射频链路的设计变得复杂，而实现射频架构多种场景兼容将使得射频链路的设计简单而便捷。
目前1T4R和2T4R的兼容方案，设计架构复杂，采用3P3T等不成熟物料(T数越多性能越差)，并且走线较长，影响总体的发射接收性能。并且3P3T或者4P4T在性能上都差于DPDT开关(double-pole-double-throw switch，双刀双掷开关)，从而导致接收通路总体损失较大。同时因为新物料价格效应，成本会远高于DPDT。此外，目前的设计方案存在不用的端口，比较浪费，同时会占用更多的PCB面积，提高了设计的复杂度和终端产品的成本。
