Abstract
A radio receiver such as a frequency modulation (FM) receiver, for example, includes a radio frequency (RF) amplifier having an adjustable gain output. The RF amplifier may be configured to receive and amplify an incoming RF signal. The receiver also includes an intermediate frequency (IF) amplifier having an adjustable gain output. The IF amplifier may be configured to receive and amplify an IF signal that corresponds to the RF signal. The receiver also includes a gain control unit that is coupled to the RF amplifier and the IF amplifier. The gain control unit may be configured to independently adjust the gain of each of the RF amplifier and the IF amplifier, dependent upon a peak output level of both the RF amplifier and the IF amplifier.
