Abstract

In this paper, a microstrip filtering Class-F power amplifier (PA) is proposed by using an output impedance transformer (IT) with a dual-mode bandpass response the lengths of the drain bias stub and coupled feed line are elaborately selected to meet the requirements of a Class-F operation the fabricated circuit is centered at 3.5 GHz for 5G applications the maximum gain at saturation is 11.4 dB with Pout>38.5 dBm the maximum power added efficiency (PAE) is around 63% while the effective bandwidth under PAEs > 50% is 250 MHz.
