Abstract
A heterodyne receiver comprising a gain controllable RF mixer () which has a first input connected to a first local oscillator () and a second input connected to an RF input. The receiver comprises a peak detector () which detects a peak value of an input signal at the second input of the HF mixer and generates a digital control signal if it is determined that the peak value of the input signal is above a predetermined level. A digital automatic gain control circuit () decreases upon reception of the digital control signal the gain of the RF mixer.
