Abstract
Embodiments of a multiple-path amplifier (e.g., a Doherty amplifier) and a module housing the amplifier include a first amplifier (or first power transistor die) with a first output terminal, a second amplifier (or second power transistor die) with a second output terminal, and an impedance inverter line assembly electrically connected between the first and second output terminals. The impedance inverter line assembly includes a first transmission line and a surface mount component connected in series between the first and second output terminals. In various embodiments, the surface mount component is selected from a fixed-value capacitor, a fixed-value inductor, a tunable capacitor, a tunable inductor, and a tunable passive component network.
