技术领域
本公开实施例涉及电子技术领域，尤其涉及一种射频装置及终端设备。
背景技术
相关技术中的射频架构中，为确保发射功率的稳定性，需要对发射功率做监测，以实现发射功率实时可控，从而需要引入了一个定向耦合器串接于发射(Transmit，TX)和主集接收(Primary Receive，PRX)通路中，由此对发射和主集接收通路都引入了一个***损耗，这个***损耗也就是定向耦合器带来的损耗，其一般在0.3dB左右。定向耦合器的耦合系数一般在25dB左右，也即在发射功率为23dBm时，定向耦合器耦合并发送到射频收发器用以功率检测的信号幅度大约在-2dBm左右。
因此，为了使得天线口能得到固定的功率，比如是23dBm，那么就需要送到定向耦合器的功率是23+0.3＝23.3dBm，需要射频功率放大器多输出0.3dBm的功率，由此功率放大器消耗的电流大约会增加15mA(通常情况下，功率放大器的输出功率增加1dB，功率放大器的消耗电流增加50mA)，从而将影响到终端设备的电池的续航时间，进而在一定程度上影响用户体验，并且，由于定向耦合器的***损耗的引入，对主集接收的接收灵敏度也会有0.3dB左右的恶化，影响射频接收性能。
由上述内容可知，相关技术中的射频架构为确保发射功率的稳定性，将引入较大插损，增加发射和主集接收通路中的器件功率损耗，并且会对射频接收性能造成影响。

第三方面，本公开实施例提供一种终端设备，包括上述第一方面的实施例提供的射频装置。
第四方面，本公开实施例提供一种终端设备，包括上述第二方面的实施 例提供的射频装置。

需要说明的是，在本文中的一个或多个实施例中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
在本公开中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”、“设置”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本公开中的具体含义。
另外，本公开可以在不同实施例或示例中重复参考数字和/或字母。这种 重复是为了简化和清楚的目的，其本身不指示所讨论各种实施例和/或设置之间的关系。
此外，在发明实施例中，诸如第一和第二等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。
上面结合附图对本公开的实施例进行了描述，但是本公开并不局限于上述的具体实施方式，上述的具体实施方式仅仅是示意性的，而不是限制性的，本领域的普通技术人员在本公开的启示下，在不脱离本公开宗旨和权利要求所保护的范围情况下，还可做出很多形式，均属于本公开的保护之内。
