Abstract
A transmission output detecting circuit for use in a radio transmitter-receiver of a TDD communication system having a TDD switch for connecting a transmission system to an antenna system in a transmitting period and for connecting a reception system to the antenna system in a receiving period; comprising a detection means for detecting transmission output on the basis of leakage power of the TDD switch in the transmitting period. The transmission output can be detected with low power consumption without making the transmission power branch out.
