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 1):
A radio frequency (RF) control circuit comprising:\n power amplifier (PA) circuitry configured to amplify an RF signal based on a bias voltage and generate a PA feedback signal comprising a PA signature; and control circuitry coupled to the PA circuitry and configured to:\n receive the PA signature; \n determine a performance deviation between an actual PA performance parameter and a target PA performance parameter based on the PA signature; and \n adjust the bias voltage of the PA circuitry in one or more corrective iterations to reduce the performance deviation to a predetermined performance deviation threshold.
