Abstract :
High-Electron-Mobility-Transistor can operate with very small gate length below 0.5 μm and it attracts applications at very high frequency - in the THz range. In particular HEMTs have shown power gain at frequencies greater than 1THz.. This device has an improved trans-conductance and carrier saturation velocity. HEMT offers high power efficiency, greater consistency and broader bandwidth in wireless communication system. The polarization and power characteristics of the AlGaN/AlN combination have been presented in this paper.
