In this paper, a quad-band inverse class-F power amplifier using the novel composite right/left-handed (CRLH) transmission lines (TLs) is developing covering 700 MHz, 800 MHz, 1800 MHz, and 2140 MHz. The novel CRLH TL metamaterials with two left-handed (LH) (backward) and two right-handed (RH) (forward) pass bands are used for quad-band operation. The second- and third-harmonics for four bands are located on open and short impedances for high-efficiency inverse class-F power amplifier. With the inverse class-F output matching network based on the quad-band harmonic control circuits, the measured maximum power-added efficiency (PAE) of the proposed quad-band inverse class-F power amplifier is 58.2%, 50.3%, 48.6%, and 56.6% for an output power of 41.5 dBm, 39.7 dBm, 37.7 dBm, and 40.7 dBm at 700 MHz, 800 MHz, 1800 MHz, and 2140 MHz, respectively.
