Abstract
A system for compensating impedance mismatch at an output terminal of a RF power amplifier is disclosed. In an embodiment, the system includes a plurality of samplers to measure a first set of parameters associated with an amplified signal being generated by the power amplifier. The first set of parameters is transmitted to a processing unit. The processing unit varies an impedance of an impedance element based on the first set of parameters. The impedance element is connected to the output terminal of the power amplifier.
