Abstract
A system for use with a transmitter and an antenna includes a radio frequency power detection portion, a tunable matching network, and a phase lock loop. The tunable matching network has a modifiable impedance to account for impedance mismatch between the transmitter and the antenna. The phase lock loop tunes the tunable matching network to modify the modifiable impedance.
