摘要： The behavioral model and predistorter for modeling and reducing nonlinear effects in power amplifiers addresses the model size estimation problem. The GMP model is replaced by the hybrid memory polynomial/envelope memory polynomial (HMEM) model within a twin nonlinear two-box structure to reduce the number of variables involved in the model size estimation problem, without compromising model accuracy and digital predistorter performance. A sequential approach is presented to efficiently estimate the model size. Experimental validation is carried out to evaluate the performance of the size estimation and the accuracy of the HMEM-based twin-nonlinear two-box model with respect to that of the GMP-based twin-nonlinear two-box model.

摘要： A radio frequency (RF) system includes an RF power amplifier (PA), which uses an envelope tracking power supply voltage to provide an RF transmit signal, which has an RF envelope; and further includes an envelope tracking power supply, which provides the envelope tracking power supply voltage based on a setpoint.

The envelope control circuitry provides the setpoint, such that the envelope tracking power supply voltage is clipped to form clipped regions and substantially tracks the RF envelope between the clipped regions, wherein a dynamic range of the envelope tracking power supply voltage is limited. The RF modulator provides an RF input signal to the RF PA, which receives and amplifies the RF input signal to provide the RF transmit signal.

摘要： An RF PA system that generates its own local characterization information. The RF PA system includes a PA to generate a RF output signal from a RF input signal, the PA powered by a supply voltage. A characterization block generates characterization information corresponding to a relationship between the supply voltage and performance (e.g., gain, power efficiency, distortion, receive band noise) of the RF PA system for a plurality of levels of one or more operating conditions (e.g., temperature, operating frequency, modulation format, antennae mismatch, etc.) of the RF PA system. An amplitude estimator block estimates an amplitude of the RF input signal. A supply control block generates a supply voltage control signal for controlling the supply voltage based on the characterization information and the amplitude of the RF input signal.
