Abstract

An enhancement-mode pseudomorphic inverted HEMT with short gate length shows superior saturation properties at low drain voltage. Such saturation properties are suitable for low-supplied-voltage applications. High-frequency properties of FETs were also studied, using two types of frequency-dependent measurement systems which represent active load and common-source circuits. It was confirmed that low knee voltage in the static I-V curve is preserved above 100 kHz. The estimated output power for the device is 50% higher than that of conventional pseudomorphic HEMT at supplied voltage of 1 V.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
