ABSTRACT:
A power amplifier (517) for amplifying an operating signal includes an amplifier (538), an amplifier (540), and a power combiner (518) with harmonic selectivity. The power combiner (518) includes a transmission line section (541), a transmission line section (545), and a resistor (554). The transmission line section (541) is coupled to an amplifier output of the amplifier (538), and the transmission line section (545) is coupled to an amplifier output of the amplifier (540) and to the transmission line section (541). A capacitor (546) is coupled in parallel to a transmission line section (542) of the transmission line section (541), and a capacitor (548) is coupled in parallel to a transmission line section (544) of the transmission line section (545).
