In active quasi-optics, we demonstrated the first successful monolithic HBT and pHEMT millimeter-wave grid amplifiers. In addition, we demonstrated a diode doubler grid with a record output of 24 mW at 1 THz. We also developed a series of Class-E amplifiers for communications and radar that are based on power MOSFETs with output powers in the frequency range from 7 to 14 MHz of 300 to 500 W, and efficiencies of 90. We recently extended this work to demonstrate VHF and UHF Class-E amplifiers.
