Abstract
Circuitry, which includes a package interface, an RF amplification circuit, and a closed-loop phase linearization circuit, is disclosed. The package interface receives an RF signal and provides an amplified RF signal. The RF amplification circuit amplifies the RF signal to generate the amplified RF signal, such that an intermediate RF signal is generated during amplification of the RF signal. The closed-loop phase linearization circuit endogenously establishes a target phase of the amplified RF signal using the RF signal. Further, the closed-loop phase linearization circuit applies a phase-shift to the intermediate RF signal based on a difference between the target phase and a measured phase, which is representative of a phase of the amplified RF signal, wherein the phase-shift reduces phase distortion in the amplified RF signal.
