Claim Text:
1. An output network circuit for multi-harmonic control of a radio-frequency (RF) power amplifier, the circuit comprising: an impedance matching network having an input and an output, and configured for a fundamental frequency (f a broadband harmonic trap having an input and an output, the output of the broadband harmonic trap coupled to the input node of the impedance matching network, the broadband harmonic trap configured to substantially trap a plurality of harmonics associated with the fundamental frequency; and a dipole network having an input and an output, the output of the dipole network coupled to the input node of the broadband harmonic trap, the input of the dipole network coupled to an output of an amplifying transistor of the RF power amplifier, the dipole network configured to tune reactances resulting from the operation of the broadband harmonic trap.
