A 2 W, high efficiency, 2-8 GHz, cascode HBT MMIC power distributed amplifier

Abstract

In this paper a new topology for wideband power distributed amplifiers is proposed. This topology is based on a nonlinearly optimized HBT cascode cell. More than 2 W have been measured in the 2-8 GHz frequency range with an associated gain of 9 dB and a PAE higher than 20%. Those results have been found in good agreement with the simulated ones.
