为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
在相关的技术方案中，如图1所示，图1是传统的功率放大器的电路拓扑图。图1中的功率放大器包括有功率分配模块110、主路四分之一波长传输线120、主路功率放大模块130、主路输出匹配模块140、辅路功率放大模块150、辅路输出匹配模块160、辅路四分之一波长传输线170和合路四分之一波长传输线190，具体地，功率分配模块110的输入端用于接收输入信号，功率分配模块110设置有两个输出端，其中一个输出端依次通过主路四分之一波长传输线120、主路功率放大模块130和主路输出匹配模块140连接至合路点180，另一个输出端依次通过辅路功率放大模块150、辅路输出匹配模块160和辅路四分之一波长传输线170连接至合路点180，接着合路点180再通过合路四分之一波长传输线190连接至负载。
在一些示例中，若负载的阻抗为50Ω，那么为了保证功率放大器的高输出效率，需要使得合路四分之一波长传输线190的输出端的输出阻抗也同样为50Ω，当所使用的合路四分之一波长传输线190的阻抗为35Ω时，那么根据合路四分之一波长传输线190的阻抗变换特性， 需要使得合路四分之一波长传输线190的输入端的输入阻抗约为25Ω。
当功率回退-6dB时，即功率分配模块110的输入信号为小信号时，主路功率放大模块130开启，辅路功率放大模块150关闭，主路功率放大模块130的输出阻抗为ZmodΩ，经过主路输出匹配模块140的阻抗变换处理后，主路输出匹配模块140的输出阻抗为25Ω，由于辅路功率放大模块150关闭，所以主路的负载阻抗没有受到辅路的有源负载牵引，因此，合路点180的输出阻抗仍为25Ω，即可以使得合路四分之一波长传输线190的输入端的输入阻抗约为25Ω，从而可以保证功率放大器的高效率输出。因此，当功率回退-6dB时，主路功放负载端到主路功率放大模块130的阻抗变换过程是：由50Ω经过合路四分之一波长传输线190之后变换为25Ω，再经过主路输出匹配模块140变换为ZmodΩ；另外，辅路功率放大模块150关断。
当功率回退0dB时，即功率分配模块110的输入信号为大信号时，主路功率放大模块130和辅路功率放大模块150均开启，主路功率放大模块130的输出阻抗为ZmaxΩ，经过主路输出匹配模块140的阻抗变换处理后，主路输出匹配模块140的输出阻抗为50Ω，同时，辅路功率放大模块150的输出阻抗为ZmaxΩ，经过辅路输出匹配模块160的阻抗变换处理后，辅路输出匹配模块160的输出阻抗为50Ω，由于辅路四分之一波长传输线170的阻抗为50Ω，因此，根据辅路四分之一波长传输线170的阻抗变换特性，辅路四分之一波长传输线170的输出阻抗为50Ω，由于主路和辅路的输出阻抗均为50Ω，因此，并联之后的合路点180的输出阻抗仍保持为25Ω，从而也可以保证功率放大器的高效率输出。因此，当功率回退0dB时，主路功放负载端到主路功率放大模块130的阻抗变换过程是：由50Ω经过合路四分之一波长传输线190之后变换为25Ω，由于主路的输出阻抗会受到辅路的负载牵引，那么经过合路点180之后会变换为50Ω，接着再经过主路输出匹配模块140变换为ZmaxΩ；另外，辅路功放负载端到辅路功率放大模块150的阻抗变换过程是：由50Ω经过合路四分之一波长传输线190之后变换为25Ω，由于辅路的输出阻抗会受到主路的负载牵引，那么经过合路点180之后会变换为50Ω，再经过辅路四分之一波长传输线170变换为50Ω，接着再经过辅路输出匹配模块160变换为ZmaxΩ。
基于上述图1中的功率放大器，由于其具有上述改善功放效率的作用，因此，图1中的功率放大器已经广泛应用于无线通信基站中。但是，随着通信技术演变到5G时代，采用了Massive MIMO技术，从而对功放在高效率和小型化等方面的设计提出了更高的要求，而图1中的功率放大器已经无法满足上述要求。
基于上述情况，本申请实施例提供了一种功率放大器、信号处理方法、发射机和基站设备，其中，功率放大器包括但不限于有主路功率放大模块、主路输出匹配模块、辅路功率放大模块、辅路输出匹配模块和合路输出匹配模块，具体地，主路输出匹配模块的输入端与主路功率放大模块连接，辅路输出匹配模块的输入端与辅路功率放大模块连接，合路输出匹配模块的输入端与主路输出匹配模块和辅路输出匹配模块的合路输出端连接；其中，主路功率放大模块被设置成对主路输入信号进行功率放大以得到主路功率放大信号，主路输出匹配模块被设置成对主路功率放大信号进行调整以得到主路输出信号；辅路功率放大模块被设置成对辅路输入信号进行功率放大以得到辅路功率放大信号；辅路输出匹配模块被设置成对辅路功率放大信号进行调整以得到辅路输出信号；合路输出匹配模块被设置成对合路输出端的输出信号进行调整以得到目标输出信号，其中，合路输出端的输出信号包括主路输出信号或者 包括主路输出信号和辅路输出信号的合路信号。根据本申请实施例的技术方案，本申请实施例的功率放大器相对于图1中现有的功率放大器，去掉了辅路四分之一波长传输线以及合路四分之一波长传输线，不但能够实现功率放大器的小型化，而且还能够降低线损从而提升功率放大器的效率；其次，主路的主路功率放大模块和辅路的辅路功率放大模块能够共用合路的合路输出匹配模块，从而有助于功率放大器的小型化。
下面结合附图，对本申请实施例作进一步阐述。
如图2所示，图2是本申请一个实施例提供的功率放大器的电路拓扑图。本申请实施例的功率放大器包括但不限于有主路功率放大模块230、主路输出匹配模块240、辅路功率放大模块250、辅路输出匹配模块260和合路输出匹配模块280。
具体地，主路功率放大模块230被设置成对主路输入信号进行功率放大，得到主路功率放大信号；主路输出匹配模块240与主路功率放大模块230连接，主路输出匹配模块240被设置成对主路功率放大信号进行调整，得到主路输出信号；辅路功率放大模块250被设置成对辅路输入信号进行功率放大，得到辅路功率放大信号；辅路输出匹配模块260与辅路功率放大模块250连接，辅路输出匹配模块260被设置成对辅路功率放大信号进行调整，得到辅路输出信号；合路输出匹配模块280与主路输出匹配模块240和辅路输出匹配模块260的合路输出端270连接，合路输出匹配模块280被设置成对合路输出端270的输出信号进行调整，得到目标输出信号；其中，合路输出端270的输出信号包括主路输出信号或者包括主路输出信号和辅路输出信号的合路信号。
在一些示例中，若负载的阻抗为50Ω，那么为了保证功率放大器能够输出高功率给负载，需要控制合路输出匹配模块280的输出端的输出阻抗也同样为50Ω，由于合路输出匹配模块280自身带有一定的阻抗，因此，根据合路输出匹配模块280所需要的输出阻抗和合路输出匹配模块280的自身阻抗，可以得到合路输出匹配模块280的输入端所需要的输入阻抗，在一些示例中，将合路输出匹配模块280的输入端所需要的的输入阻抗记为Re(Zmod)Ω，具体地，关于图2中的功率放大器的工作阶段，可以包括但不限于如下几个工作阶段：
小信号阶段：在一些示例中，当功率回退-6dB时，即主路输入信号和辅路输入信号均为小信号时，由于主路输入信号的功率大于主路功率放大模块230的主路开启功率阈值，主路功率放大模块230开启；同时，由于辅路输入信号的功率小于辅路功率放大模块250的辅路开启功率阈值，辅路功率放大模块250关断。若主路功率放大模块230的输出阻抗为ZmodΩ，那么经过主路输出匹配模块240的阻抗变换处理后，主路输出匹配模块240的输出阻抗为Re(Zmod)Ω，同时，由于辅路功率放大模块250关闭，所以主路的输出阻抗没有受到辅路的有源负载牵引，因此，合路输出端270的输出阻抗即为Re(Zmod)Ω，即可以使得合路输出匹配模块280的输入端的输入阻抗为所需要的Re(Zmod)Ω，从而可以保证功率放大器的高效率输出。另外，基于上述小信号阶段的工作过程，可以知道当功率回退-6dB时，主路功放负载端到主路功率放大模块230的阻抗变换过程是：由50Ω经过合路输出匹配模块280之后变换为Re(Zmod)Ω，再经过主路输出匹配模块240变换为ZmodΩ；另外，辅路功率放大模块250关断。
大信号阶段：在一些示例中，当功率回退0dB时，即主路输入信号和辅路输入信号均为大信号时，由于主路输入信号的功率大于主路功率放大模块230的主路开启功率阈值，主路功率放大模块230开启；同时，由于辅路输入信号的功率大于辅路功率放大模块250的辅路 开启功率阈值，辅路功率放大模块250也开启。若主路功率放大模块230的输出阻抗为ZmaxΩ，经过主路输出匹配模块240的阻抗变换处理后，主路输出匹配模块240的输出阻抗为2Re(Zmod)Ω，同时，辅路功率放大模块250的输出阻抗为ZmaxΩ，经过辅路输出匹配模块260的阻抗变换处理后，辅路输出匹配模块260的输出阻抗为2Re(Zmod)Ω，由于主路和辅路的输出阻抗均为2Re(Zmod)Ω，因此，并联之后的合路输出端270的输出阻抗会变为Re(Zmod)Ω，即可以使得合路输出匹配模块280的输入端的输入阻抗为所需要的Re(Zmod)Ω，从而也可以保证功率放大器的高效率输出。另外，基于上述大信号阶段的工作过程，可以知道当功率回退0dB时，主路功放负载端到主路功率放大模块230的阻抗变换过程是：由50Ω经过合路输出匹配模块280之后变换为Re(Zmod)Ω，由于主路的输出阻抗会受到辅路的负载牵引，那么经过合路输出端270之后会变换为2Re(Zmod)Ω，接着再经过主路输出匹配模块240变换为ZmaxΩ；另外，辅路功放负载端到辅路功率放大模块250的阻抗变换过程是：由50Ω经过合路输出匹配模块280之后变换为Re(Zmod)Ω，由于辅路的输出阻抗会受到主路的负载牵引，那么经过合路输出端270之后会变换为2Re(Zmod)Ω，接着再经过辅路输出匹配模块260变换为ZmaxΩ。
由小信号阶段向大信号阶段的过渡阶段，基于上述小信号阶段的工作过程和大信号阶段的工作过程的分析，当由小信号阶段向大信号阶段过渡时，主路功率放大模块230的输出阻抗会由ZmodΩ逐渐过渡为ZmaxΩ，主路输出匹配模块240的输出阻抗会由Re(Zmod)Ω逐渐过渡为2Re(Zmod)Ω；另外，辅路输出匹配模块260的输出阻抗会由无穷大逐渐过渡为2Re(Zmod)Ω。
由大信号阶段向小信号阶段的过渡阶段，基于上述小信号阶段的工作过程和大信号阶段的工作过程的分析，当由大信号阶段向小信号阶段过渡时，主路功率放大模块230的输出阻抗会由ZmaxΩ逐渐过渡为ZmodΩ，主路输出匹配模块240的输出阻抗会由2Re(Zmod)Ω逐渐过渡为Re(Zmod)Ω；另外，辅路输出匹配模块260的输出阻抗会由2Re(Zmod)Ω逐渐过渡为无穷大。
因此，基于上述图2中的功率放大器的多个工作阶段的分析，本申请实施例的功率放大器具有改善功放效率的作用，可以适合应用于无线通信基站中。
根据本申请实施例的技术方案，本申请实施例的功率放大器相对于图1中现有的功率放大器，去掉了辅路四分之一波长传输线以及合路四分之一波长传输线，并且在合路添加了合路输出匹配模块280兼顾主路的匹配和阻抗变换，以及在辅路使用辅路输出匹配模块260替换传统的辅路输出匹配模块和辅路四分之一波长传输线，不但能够实现功率放大器的小型化，而且还能够降低线损从而提升功率放大器的效率；其次，主路的主路功率放大模块230和辅路的辅路功率放大模块250能够共用合路的合路输出匹配模块280，从而有助于功率放大器的小型化。
另外，如图2所示，本申请实施例的功率放大器中的主路输出匹配模块240包括但不限于有短路枝节241和微带线242，具体地，短路枝节241和微带线242的一端连接至主路功率放大模块230的输出端，短路枝节241的另一端连接至地，微带线242的另一端连接至合路输出端270。另外，本申请实施例的功率放大器中的主路输出匹配模块240还可以包括有电容243，具体地，电容243的一端连接至合路输出端270，电容243的另一端连接至地。
由于本申请实施例的主路输出匹配模块240采用了短路枝节241和微带线242，或者采 用了短路枝节241、微带线242和电容243，可以使得合路输出端270能够放置到更靠近主路功率放大模块230输出的位置，从而使得主路的输出阻抗更低，更能降低辅路接入带来的牵引影响，有助于提升功放的宽带性能。其次，主路功率放大模块230输出根部的短路枝节241、电容243、以及两者之间的微带线242共同提供了电流Im(Zmod)，同时还对基波的二次谐波进行抑制从而提升功放效率。
另外，如图2所示，本申请实施例的功率放大器还包括但不限于有功率分配模块210，具体地，功率分配模块210设置有主路功率输出端和辅路功率输出端，主路功率输出端连接至主路功率放大模块230的输入端，辅路功率输出端连接至辅路功率放大模块250的输入端，功率分配模块210被设置成对输入信号进行功率分配，得到主路输入信号和辅路输入信号。
本申请实施例采用功率分配模块210将主路功率放大模块230和辅路功率放大模块250组合起来，能够对输入信号进行功率分配，得到主路输入信号和辅路输入信号，并将主路输入信号通过主路功率输出端发送至主路功率放大模块230，以及将辅路输入信号通过辅路功率输出端发送至辅路功率放大模块250。
另外，如图2所示，本申请实施例的功率放大器还包括但不限于有主路相位补偿模块220或者辅路相位补偿模块，具体地，主路相位补偿模块220连接至主路功率放大模块230的输入端，主路相位补偿模块220被设置成对主路输入信号进行相位补偿处理。或者，辅路相位补偿模块连接至辅路功率放大模块250的输入端，辅路相位补偿模块被设置成对辅路输入信号进行相位补偿处理。
