Abstract
A Multi-Mode Multi-Band (MMMB) radio frequency (RF) power amplifier circuit operating at multiple frequency bands. The power amplifier circuit comprises a single wideband power amplifier having high output impedance which is configured to be equal to a load impedance of the load connected to the power amplifier circuit. A bias voltage applied to the wideband power amplifier is changed from a first value to a second value to provide a predetermined output power of the wideband power amplifier to the load with the output impedance of wideband power amplifier being equal to the load impedance. The power amplifier circuit also includes an individual harmonic filter for filtering each frequency band independently.
