Amplitude correction circuit
 With the circuit construction of a heterodyne receiver, a control circuit for correcting the amplitude level of a local oscillation signal according to an output signal of a detector circuit is connected to the output terminal of an amplifier for amplifying the local oscillation signal to set the amplitude level of the local oscillation signal input to the mixer to an adequate level.
