摘要： At an amplifying time, a first switching circuit 103 is controlled so that an input signal is amplified by a power amplifier 102, thereafter the input signal is output to a circulator 106, and a second switching circuit 104 is controlled so that the circulator 106 is terminated by a fixed resistor 111 in accordance with circuit's characteristic impedance. Also, at a non-amplifying time, the first switching circuit 103 and the second switching circuit 104 are controlled so that the input signal is output to the circulator 106, and a third switching circuit 105 is controlled so that drain power 109 of the power amplifier 102 and gate power 110 thereof are switched off. This makes it possible to carry out bypass control of the power amplifier without increasing a circuit current.

摘要： A transceiver circuit with a heterodyne receiver circuit is provided. Output signals of first and second local oscillator 103, 104 are mixed by a local frequency converter 105. An output signal of the converter 105 passes a filter 106 and inputs a modulator 111 of a transmitter circuit 101 as well as a first frequency converter 122 of a receiver circuit 102. The second local oscillator 104 comprises a frequency synthesizer whose output signal varies for a transmission or a receiving mode. The output signal of the second local oscillator 104 also inputs the second frequency converter 124 of the receiving mode. A reference frequency of the second local oscillator 104 is set higher than a frequency step between communication channels so that a quick switching of the frequency is performed. Thus, the transceiver circuit of this invention is suitable for a compact size and hardly generates unwanted spurious components at transmission mode.
