摘要： Embodiments of a radio frequency (RF) amplification device having an RF amplification circuit and an amplifier control circuit operably associated with the RF amplification circuit are disclosed. The RF amplification circuit is configured to amplify an RF signal in accordance with a transfer function. The amplifier control circuit includes a closed-loop linearization circuit and a calibration circuit. The closed-loop linearization circuit is configured to be activated so that the transfer function defines a closed-loop response and inactive so that the transfer function defines an open-loop response. For example, the closed-loop linearization circuit may become inactive at small-signal power levels. Accordingly, the amplifier control circuit also includes a calibration circuit configured to reduce a difference between the open-loop response and the closed-loop response of the transfer function. In this manner, the performance of the RF amplification device is maintained while the closed-loop linearization circuit is inactive.

摘要： 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.
