The Hughes/GE team is developing and validating several processes: continuation of the signal and power MESFET process work begun during Phase 1; 0.25-[micro-m] pseudomorphic high electron mobility transistor processes for several frequency ranges to improve the performance of amplifiers, VCOs and mixers; and an HBT process for high-power amplifiers at X-band.
