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 .
