US Patent 9973148 Radio frequency system with switch to receive envelope

Aspects of this disclosure relate to a radio frequency system that includes an envelope generator configured to generate an envelope signal corresponding to an envelope of a radio frequency signal and at least two radio frequency components coupled to the envelope generator. One of the radio frequency components is a radio frequency switch configured to pass the radio frequency signal. The radio frequency switch is configured to receive the envelope signal to cause intermodulation distortion associated with the radio frequency switch to be reduced.
