Abstract

PURPOSE:To cancel the disturbance signal of the adjacent channels, by securing a phase difference of 180 deg. between the adjacent channel disturbance intermediate frequency signals and then adding those signals together after giving the level control. CONSTITUTION:The output of high frequency amplifier 2 is distributed to mixers 4 and 5 through distributor 3 to be mixed with the oscillation output of local oscillator 6 at mixer 4 and to be amplified selectively at intermediate frequency amplifier 7, and also to be mixed with the oscillation output of local oscillator 8 at mixer 5 and to be amplified selectively at intermediate frequency amplifier 9. the output of amplifier 7 is mixed up with the output of amplifier 9 obtained via level adjuster 10 through phase adder 11 to be delivered to terminal 13.
