ABSTRACT:
An amplifier system for a radio receiver, comprising: an amplifier chain having a first amplifier for receiving a signal derived from a received radio signal and amplifying it to generate a first amplifier signal, and a second amplifier for receiving a signal derived from the first amplifier signal and amplifying it to generate a second amplifier signal; a sensor means for sensing the level of a signal at a point in the amplifier chain; and amplifier control means responsive to the sensor means for, when a relatively high level of signal is sensed, controlling the first and second amplifiers to improve their response.
