技术领域
本申请属于通信技术领域，具体涉及一种发射链路的处理方法、装置及终端。
背景技术
终端的发射链路通常包含收发机(transceiver)，功率放大器(Power Amplifier，PA)，开关(switch)，滤波器(Filter)，天线等。收发机输出的信号经过PA放大后经天线发出。PA是需要进行供电的，因为实现的限制，PA不能将输入功率完全转换为输出功率。PA效率大致可以定义为PAE＝(Pout–Pin)/P DC，其中Pout为PA输出信号功率，Pin为PA输入信号功率，P DC为PA的直流供电功率。
在实现本申请过程中，发明人发现相关技术中至少存在如下问题：
基于终端PAE测试结果，可以看到在PA输出信号功率较低(例如15dBm以下)时，PAE<10％，也就意味着给PA供电的90％功率被消耗了。换言之，相关技术存在终端PA效率低的问题，导致过多的功率消耗，对终端节能不利。
