Abstract

This disclosure is directed to power gain variation compensation of Radio Frequency (RF) receivers based on temperature variations. An RF receiver may include amplification circuitry having a chain of multiple amplifiers and/or passive elements. Multiple distributed and/or lumped attenuators disposed at different points between amplifiers and/or passive elements of the chain may attenuate a received RF signal to compensate for gain variations of the multiple amplifiers and/or passive elements caused by a temperature change. Accordingly, the distributed and/or lumped attenuators may improve linear response of the amplifiers and/or passive elements and signal-to-noise and distortion ratio of RF signals received at the receiver.
