Abstract

An RF receiver (100) including an RF amplifier (105) for amplifying a received input RF signal, a mixer (107) for converting an RF signal produced as an output by the RF amplifier to a baseband signal, a baseband receiver channel (115) for processing the baseband signal, the baseband receiver channel including a baseband amplifier (127), an AGC (automatic gain control) loop (130) coupled from the baseband receiver channel to the RF amplifier to provide automatic gain control of the RF amplifier, an off-channel detector (163) operable to detect activation of the AGC loop by an unwanted received off-channel signal and a control loop (145) coupled from the detector to the baseband amplifier (127) to apply a control signal to the baseband amplifier to reduce a gain of the baseband amplifier when the off-channel detector detects an unwanted received off-channel signal. Also described is a wireless communication terminal and a method of operation in the receiver.
