Abstract: A temperature compensation circuit (26) is used to provide a reference signal in a feed forward gain control loop (28). With such an arrangement, gain control is provided wherein variations of an output signal of the amplifier circuit (10) due to changing characteristics of amplifier elements (12,18) of the amplifier circuit (10) caused by ambient temperature variation or a varying input signal level are minimized. Part of the amplified (12) input signal is supplied by a coupler (14) to a detector (20) followed by a low pass filter (22) that supplies one input of a differential amplifier (24) that receives the reference signal and supplies a control signal to a controllable attenuator (16).
