Abstract

In this work, a wide bandwidth Sequential Power Amplifier (SPA) is demonstrated for the first time. Using wideband and high efficiency 10W and 45W amplifiers, an SPA is described, capable of delivering high efficiency at back-off without the bandwidth limitations of the traditional Doherty PA. Measurement results of the implemented amplifier are presented, with an average back-off drain efficiency of 59% achieved between 1.45 GHz and 2.4 GHz, and a peak back-off drain efficiency of 65% at 1.7 GHz.
