摘要: We report the results of a high-performance all-solid-state broad-band frequency multiplier chain at 1500 GHz, which uses four cascaded planar Schottky-barrier varactor doublers. The multipliers are driven by monolithic-microwave integrated-circuit-based high electron-mobility transistor power amplifiers around 95 GHz with 100-150 mW pump power. design incorporates balanced doublers utilizing novel substrateless and membrane device fabrication technologies, achieving low-loss working in terahertz range. For drive approximately 100 88-99-GHz range, achieved room-temperature peak efficiencies 30% 190-GHz stage, 20% 375 9% 750 4% 1500-GHz stage. When was cooled to 120 K, 40 /spl mu/W output measured for input
