  • Abstract
    Single pulse doped, 0.2 μm-gate Al0.60In0.40 As/GaInAs/InP HEMTs have been fabricated and characterised. The complete process sequence for the HEMTs includes SiNx passivation and dry etched via hole fabrication. Power measurements at 44 GHz on a 10×60 μm2 device yielded 225 mW output power, 5 dB associated gain, and 39% power added efficiency. The results indicate that the single pulse doped InP-based HEMTs are suitable for high power applications at Q-band
