Metamorphic HEMT Technology for Microwave, Millimeter-Wave, and Submillimeter-Wave Applications
This paper reviews recent progress in the development of GaAs Metamorphic HEMT (MHEMT) technology for microwave, millimeter-wave, and submillimeter-wave applications. Short gate-length (50-100 nm) Metamorphic High Electron Mobility Transistors have been optimized for high gain and low noise performance. Efforts to further improve performance, manufacturability, and verify reliability will be reported. We also describe the design and performance of low noise MMIC amplifiers based on this technology.
