Abstract
An RF power amplifier circuit includes a power divider, multiple power amplification circuits and a power combiner that cooperatively perform power amplification on an RF input signal so as to output an RF output signal, and an impedance conversion circuit that has a circuit terminal coupled to one of the power divider and the power combiner which has a microstrip structure, and that is configured such that a conversion impedance, which is an impedance seen into the impedance conversion circuit from the circuit terminal, matches an impedance seen into the power divider or the power combiner from the circuit terminal. The microstrip structure has a physical length associated with the conversion impedance.
