Abstract

This paper presents a 30-to-40 GHz 2-stage power amplifier (PA) for 5G applications. Transformers are used to achieve a broad input, output and interstage matching while occupying a compact size. The neutralization technique is used to boost the power gain and improve stabilities of PA. According to the simulation results, the power amplifier achieves an output 1dB compression point (OP1dB) of 14.9 dBm and a saturated output power of 17.4 dBm with a peak PAE of 39% at 35 GHz. The gain is larger than 30 dB from 30-40 GHz. Implemented in 0.13 µm SiGe BiCMOS process, the overall chip size is 0.46 mm2 including all RF and DC pads.
