Abstract
A transmit-receive switching circuit provided between a transmitter circuit configured to generate a transmission signal to be transmitted from an antenna and a receiver circuit configured to receive a reception signal received by the antenna, a transistor input control circuit configured to make the transmitter generate a transmission signal by an amplifying operation of a transistor in an output stage of the transmitter circuit when the transmission signal is transmitted from the antenna, and to short-circuit an output terminal of the transmitter circuit to a ground voltage when the reception signal is received by the antenna.
