The growth of the point to point and the point to multipoint radio markets has produced a demand for high power, low distortion and cost effective amplifier at quasi-millimeter-wave. This paper describes a GaAs-based monolithic microwave integrated circuit (MMIC) amplifier having watt-level power performance, excellent third order intermodulation distortion (IMD3) characteristic at 38 GHz-band for various communication system applications. We have developed GaAs-based double-doped heterojunction FETs (HJFET) for quasi-millimeter-wave MMIC amplifier, using highly-uniform 0.2 μm WSi-gate process on 5-inch GaAs wafer.
