Abstract

PURPOSE:To make it possible to excite a mixer by a local oscillator which provides a small output, by amplifying in common a local oscillation signal from the local oscillator by means of the FF amplifier. CONSTITUTION:A signal from the local oscillator 22 is compounded with a signal from the signal input terminal 21 by the compounding device 23 and also it is amplified by the RF amplifier 24 and goes into the mixer 25. And said signal is converted to an IF signal by the mixer 25, is amplified by the amplifier 26, and is output to the terminal 27.
