Broadband Monolithic GaN Balanced Amplifier Composed of Mixed Cascade-Tandem Directional Couplers and Cascode Stages

In this paper we present a broadband monolithic balanced amplifier reaching 30 dBm output power over a range from 5.7 GHz up to 35.1 GHz. To the best of our knowledge, such broad operational bandwidth has never been reported in literature for balanced topology. The amplifier is composed of broadband...
