Abstract: This paper presents an advanced Doherty-type power amplifier architecture, which uses two driver amplifiers embedded in the Main and Peaking paths of the Doherty stage. Due to the biasing ...
Abstract: Ka-band three-stage MMIC driver amplifier with a Y-junction combiner is presented based on 0.15 μm GaAs pseudomorphic high electron mobility transistor (pHEMT) process. The compensated ...
