Abstract
A compact E-band Doherty-like load-modulated
balanced power amplifier (LMBA) with coupled transmission-
line (CTL) output network is proposed and implemented in
65-nm CMOS process. The proposed CTL simplifies the design
of output matching networks and improves the quality factor of
matching networks. A single transmission line (TL) is inserted
between the main power amplifier (PA) path and the auxiliary
PA path to tune the phase difference, eliminating the need
of an additional extra phase shift
