    Abstract:
    In this paper we report on the stage-of-the-art power performance of InP-based HEMTs at 59 GHz. Using a 448 μm wide HEMT with a gate-length of 0.15 μm, an output power of 155 mW with 4.9 dB gain, and power-added efficiency of 30.1% were obtained. By power combining two of these HEMTs we were able to achieve an output power of 288 mW with 3.6 dB gain and power-added efficiency of 20.4%. This is the highest output power reported with such a high-efficiency for InP-based HEMTs, and is comparable to the best results reported for AlGaAs/InGaAs on GaAs pseudomorphic HEMTs at this frequency.
