Abstract(in English) | High output power and high efficiency of FET is important for the base station of digital wireless communication systems. Then we have developed an AlGaAs hetero MESFET with a graded pulse doped channel. A graded pulse-doped channel that means active layer in which doping concentration increase exponentially toward buffer layer, improves output power at low quiescent drain current (Iq). At the condition of Iq=4%Idss, P1dB is increased by 9dB than our conventional MESFET. Breakdown voltage and gate leakage current are improved by insertion of AlGaAs-cap layer. The AlGaAs hetero MESFET shows high output power (540mW / mm) and high efficiency (η_ |
