Aspects of the present disclosure relate to an apparatus for wireless communication. The apparatus may include a set of power detectors configured to generate a set of analog signals respectively related to a set of output signal power levels of a set of transmit chains of a transmitter; an analog adder; a set of switching devices configured to transmit one or more selected signals in the set of analog signals to the analog adder and substantially isolate one or more unselected power detectors in the set of power detectors from the analog adder, wherein the analog adder is configured to generate a cumulative analog signal based on a sum of one or more selected signals of the set of analog signals; an analog-to-digital converter (ADC) configured to generate a digital signal based on the accumulated analog signal; and a controller configured to control the set of switching devices. 本公开的各方面涉及一种用于无线通信的装置。该装置可以包括：一组功率检测器，被配置为生成分别与发射器的一组发射链的一组输出信号功率水平相关的一组模拟信号；模拟加法器；一组开关器件，被配置为将该组模拟信号中被选择的一个或多个信号传输到该模拟加法器，并且将该组功率检测
