ABSTRACT:
Saturation of an RF front end in a radio receiver is prevented when receiving a desired radio broadcast signal via an antenna in the presence of a strong, undesired radio broadcast signal within a passband of the RF front end. An antenna signal from the antenna is coupled to the RF front end, thereby generating an amplified signal. The radio receiver demodulates the desired radio broadcast signal in response to the amplified signal, thereby generating a demodulated signal. A signal-to-noise quality parameter of the demodulated signal is determined. The antenna signal is attenuated prior to coupling it to the RF front end by an attenuation determined in response to the signal-to-noise quality parameter.
