摘要	PURPOSE:To reduce the fluctuation of a load by switching only a switch for signal route switching corresponding to transmission or reception, and always supplying power so as to share a mixer in the transmission and reception. CONSTITUTION:An RF signal received with an antenna 1 is inputted to reception signal amplifiers 21, 22 via the switch 4 to switch the transmission and reception, and it is amplified, then, is supplied to the switching side terminal 6a of the switch 6. The common terminal 6c of the switch 6 is inputted to the mixer 10 for combination transmission and reception. While, the transmission signal of an IF is supplied to the switching side terminal 6b of the switch 6, and is inputted to the mixer 10 via a common terminal 6c, and also, the output of a local oscillator 9 is inputted to the mixer 10 via a buffer amplifier 8 and a matching circuit 13, and it is converted into the RF signal, and after it passes through the common terminal 7c and the switching side terminal 7a of the switch 7, it is amplified by transmission signal amplifiers 31, 32, then, transmitted from the antenna 1 via the switch 4.
