We present the design and development of a Ka-band Doherty power amplifier (DPA) that
achieves high efficiency at power backoff (PBO) using a new load modulation scheme and a …

A two-stage Ka-band Doherty power amplifier (DPA) using a stacked field-effect transistor
(FET) cell is presented. We demonstrate, for the first time, the two critical parameters in a …

In this paper, a Ka/Q dual-band Doherty power amplifier (DPA) with simplified offset lines is
implemented in a 0.1-μm gallium arsenide (GaAs) process. It is found that the dual-band …

In this paper, we present the design of an ultracompact monolithic millimeter-wave
integrated circuit Doherty power amplifier (DPA) using a novel reconfigurable input network …

A Ka-band CMOS two-stage Doherty power amplifier (DPA) is presented, whose back-off
