Abstract :
This paper presents some recently developed MMICs based on a 0.1-μm gate-length InAlAs/InGaAs/InP HEMT process with an fmax above 600 GHz. InP-based HEMTs provide more power gain and lower noise at higher frequencies than any other transistor, including GaAs-based pHEMTs. A number of state-of-the-art InP HEMT MMICs will be presented. This includes a 150-205 GHz amplifier with 15 dB of gain, a broadband 60-140 GHz amplifier with 25 mW output power at 140 GHz, a high gain Ka-band LNA and static frequency-divider circuits operating at clock rates above 45 GHz. The high frequency performance of a next-generation 0.08-μm-gate InAlAsSb/InAlAs/InGaAs/InP HEMT technology will also be presented
