Abstract
A transmitter-receiver is simple in arrangement and can prevent a receiving circuit side from being disturbed; in which one channel is divided to provide a transmission slot and a reception slot. Transmission and reception are effected in the transmission slot and reception slot of one channel in a time division manner and a channel selection frequency synthesizer is commonly used both in the transmitting circuit and the receiving circuit. This transmitter-receiver includes a modulator circuit (40) of the transmitting circuit which has an oscillator (41) for modulating a signal into a predetermined frequency and a multiplier circuit (44) for converting an output signal of the oscillator (41) into a desired intermediate frequency. During the period of the transmission slot, the supply of a voltage to the multiplier circuit 44 is stopped.
