Abstract:
A radio frequency (RF) control circuit is provided. The RF control circuit includes power amplifier (PA) circuitry for amplifying an RF signal and control circuitry configured to improve linearity of the PA circuitry based on a PA signature(s) already available and utilized to perform digital pre-distortion (DPD) in the RF control circuit. In examples discussed herein, the control circuitry determines a performance deviation of the PA circuitry based on the PA signature and continuously adjusts a bias voltage(s) supplied to the PA circuitry until the performance deviation is reduced to a predetermined performance deviation threshold. By continuously monitoring the performance deviation based on the PA signature(s) and adjusting the bias voltage(s), the control circuitry can detect and correct an operation abnormality of the PA circuitry in a timely manner. As a result, it is possible to maintain linearity in the PA circuitry for enhanced PA performance.

Claim (Index 5):
The RF control circuit of  claim 1  wherein the control circuitry is further configured to:\n determine an adjacent channel power ratio (ACPR) deviation between an actual ACPR and a target ACPR based on the received PA signature; and \n adjust the bias voltage of the PA circuitry in the one or more corrective iterations to reduce the ACPR deviation to a predetermined ACPR deviation threshold.
