ABSTRACT:
In a transceiver that selectively transmits a modulated wave and a non-modulated wave to the outside, and receives a response signal from the outside, an S/N ratio during reception is improved. A transceiver, which selectively transmits a modulated wave and a non-modulated wave to the outside, and receives a response signal from the outside, includes an oscillator generating a predetermined carrier wave; a modulator modulating the carrier wave generated by the oscillator with a transmitted baseband signal to generate the modulated wave; a power amplifier amplifying the modulated wave being modulated by the modulator, or the non-modulated wave being not modulated by the modulator; and a circulator for sending output of the power amplifier to an antenna. When the non-modulated wave is transmitted from the antenna, switches are switched to a bypass circuit side such that the oscillator is directly connected to the power amplifier.
