Abstract
The authors report the DC and microwave performance of undoped InP/GaInAs heterostructure insulated-gate FETs employing undoped AlInAs as the gate insulator. Devices with a 1 μm gate length were fabricated and demonstrated extrinsic transconductances g m as high as 470 mS/mm at room temperature. Devices with a 2.5 μm gate length, suitable for microwave testing, were measured and demonstrated an extrapolated f max=16 GHz
