Abstract

We report on novel, high voltage InGaAs-InAlAs pHEMTs, which have been processed on an optimized epilayer and incorporate field-plate structures of different dimensions. Fabricated devices demonstrate great improvements in break-down voltage and gate leakage, while keeping the same DC and RF behaviour with respect to baseline devices, i.e. with no field-plate implemented. In addition, the field plate strongly attenuates DC-to-pulse dispersion, making these devices suitable for high-power-density RF power amplifiers.
