In this paper, we present the latest advancements of short gate length InGaAs/InAlAs/InP high electron mobility transistor (InP HEMT) devices that have achieved extremely high extrapolated Fmax above 1 THz. The high Fmax is validated through the first demonstrations of sub-MMW MMICs (s-MMICs) based on these devices including the highest fundamental transistor oscillator MMIC at 347 GHz and the highest...
We have recently developed a sub-50nm gate length InP HEMT (high electron mobility transistor) process with a peak transconductance of 2000 mS/mm at 1V. A 3-stage single-ended common source 150-220 GHz MMIC LNA demonstrates greater than 20 dB gain at 200 GHz (> 7 dB gain per stage) and is >5 dB higher LNA gain compared to the same MMIC design fabricated on our baselined 70 nm gate length InP...
rdquoWe report the first submillimeter-wave monolithic microwave integrated circuit (MMIC) amplifier with 4.4-dB measured gain at 308-GHz frequency, making it the highest frequency MMIC amplifier reported to date. In this letter, a 35-nm InP high-electron mobility transistor process has been successfully developed with a projected maximum available gain of greater than 7 dB at 300 GHz. The excellent...
