US Patent 7860473 Systems and methods for providing millimeter wave signal improvements

A radio frequency receiver includes a receiver circuit for processing RF signals, an antenna to receive millimeter wave RF signals, and an attenuator circuit, coupled between the receiver circuit and antenna. In one embodiment, the attenuator circuit may be used to determine a signal strength of the millimeter wave RF signals, compare this signal strength to a first threshold value. If the signal strength is above the first threshold value, a level of attenuation applied to the millimeter wave RF signals may then be increased.
