Abstract :
The design principles and technology of growth of pseudomorphic AIGaAs/lnGaAs heterostructure with silicon-doped canal for high frequency high power transistors as well as fabrication technology of the transistors were developed. Special attention has been paid to growth of the Al-GaAs/lnGaAs heterojunction. PHEMTs´ with the specific output power of 1.1 W/mm, PAE of 45.6 % and power gain of 6.8 dB at 17.7 GHz have been fabricated.
