Abstract:
1. A radio communication apparatus employing a time division duplex (TDD) scheme and in which data is transmitted and received simultaneously by switching between a transmission signal and a reception signal, comprising: a detector that detects a signal branched from said transmission signal transmitted during a transmission period of the TDD scheme; a generator that generates a test signal which is used for testing the detector; and a switch that supplies said test signal to the detector during a reception period of the TDD scheme, wherein: the detector comprises a diode that is tested by the test signal; and the test signal is a preset direct current for testing the diode, wherein a decision is made whether the diode is faulty or not by outputting of the preset direct current to the diode and monitoring whether an output of the diode is within a specified range or not.
