ABSTRACT:
A method and apparatus for signal gain adjustment within an RF integrated circuit (IC) include processing that begins by determining the signal strength of a received RF input signal with respect to a first signal strength scale to produce a signal strength indication. The processing continues by determining whether the signal strength indication exceeds a first high power threshold. If not, the receiver continues to process received RF signals without additional attenuation. If, however, the signal strength indication exceeds the first high power threshold, the received RF input signal is attenuated to produce an attenuated RF input signal. In addition, the first signal strength scale is shifted to produce a shifted signal strength scale. The processing continues by determining whether the signal strength of the attenuated RF input signal exceeds a high power threshold of the shifted signal strength scale or is below a low power threshold of the shifted signal strength scale.
