Abstract
An impedance-matching circuit includes a resonant circuit, first and second capacitors, and first through third inductive circuits. The resonant circuit includes a fourth inductive circuit connected in parallel with a capacitive circuit. The impedance-matching circuit receives a radio frequency power amplifier (RFPA) output signal, which includes first and second signals at first and second frequencies, respectively. A resonant frequency of the resonant circuit is between the first and second frequencies. The resonant circuit offers inductive and capacitive impedances to the first and second signals, respectively. The impedance-matching circuit generates a matched RFPA output signal including the first signal and the second signal, where the second signal is at a reduced voltage level.
