RF AMPLIFIER HAVING A TUNABLE ANTENNA CIRCUIT

Abstract:

A circuit and computer implemented method tunes an RF switching power amplifier circuit for an antenna by receiving a measurement of reflected RF signal from the antenna, receiving a measurement of current provided to the circuit from a power source, receiving a measurement of RF power provided to the antenna, adjusting a tunable antenna circuit responsive to the measurement of reflected RF signal, and adjusting a first capacitor capacitance value and a second capacitor capacitance value of a waveform shaping circuit in response to the received measurement of current and RF power.
