摘要

We present a broadband parallel-combined compact Doherty power amplifier (PA) in a 28-nm bulk complementary metal–oxide–semiconductor (CMOS) device technology for fifth-generation (5G) millimeter-wave (mm-Wave) frequency band (n257, n258, and n261) applications. The proposed Doherty PA has a single transformer (TF)-based output matching network and an equivalent quarter-wavelength line placed betw...
