1. A method, comprising:
- receiving a magnitude input and a phase input for transmission of a radio frequency (RF) signal by a RF power amplifier;
generating a digital pulse having a center position relative to an edge of a reference clock based on the phase input and having a width based on the magnitude input, wherein the digital pulse is generated during a first half of a cycle of the reference clock;
generating, during a second half of a cycle of the reference clock, a second digital pulse having a phase displaced 0.5 UI (unit interval) from a phase of the first pulse and having a width equal to the first pulse;
filtering the digital pulse with a resonant matching network to produce the RF signal corresponding to the magnitude input and the phase input; and
filtering the second digital pulse with a second resonant matching network.

Abstract
A system and method are provided for controlling a radio frequency (RF) power amplifier. A magnitude input and a phase input are received for transmission of a RF signal by the RF power amplifier. A digital pulse, having a center position relative to an edge of a reference clock based on the phase input and having a width based on the magnitude input, is generated. The digital pulse is filtered with a resonant matching network to produce the RF signal corresponding to the magnitude input and the phase input.
