Abstract :
The authors have successfully developed a 0.1 μm T-gate planar doped pseudomorphic InGaAs high-electron-mobility transistor (HEMT) process for the fabrication of low noise and power devices with record W-band performance. The low noise device has a noise figure of 2.3 dB with an associated gain of 7.5 dB at 92 GHz. When optimized for power using a planar doped channel, the device exhibited an output power of 62.7 mW with 4.0 dB gain and 13.2% power added efficiency at 94 GHz. When tuned for minimum noise, the power device achieved a noise figure of 3.0 dB with 7.4 dB associated gain at 94 GHz
