1. An apparatus for wireless communication, comprising:
a plurality of antennas including a first antenna and a second antenna;
a first amplifier;
a plurality of loads;
an antenna switch module;
an antenna switch array having a first configuration in which an output signal path from the first amplifier is coupled to the first antenna and in which an input terminal of the antenna switch module is coupled to the second antenna;
wherein the antenna switch module is configured to couple to a selected load from the plurality of loads during a calibration mode; and
a signal detector configured to detect a forward signal from the output signal path to provide a detected forward signal and to detect a reflected signal from the output signal path to provide a detected reflected signal.
