摘要： An average level detection circuit 10 outputs a level of an input signal of a baseband output signal or a mixer circuit. A smoothing circuit 11 removes an AC component from an output signal of the average level detection circuit 10. A reference comparison circuit 12 outputs a level suppression signal when an output signal of the smoothing circuit 11 exceeds a predetermined reference voltage. When the reference comparison circuit 12 outputs the level suppression signal, the limiter circuit 13 controls the bias circuit 14 to suppress a bias current of the mixer circuit. As a result, it is possible to obtain a low-current-consumption signal reception front-end circuit in which an IF output level is not significantly lowered under an unexpectedly strong input condition, and a signal reception circuit in which an error does not occur in signal reception level detection.
