Abstract :
Double-drift Si IMPATT (impact avalanche and transit time) diodes with hybrid Read profiles were designed, fabricated and tested for millimeter-wave frequency operation. Vapor phase epitaxy (VPE) growth was used to achieve well-controlled, abrupt n-type doping transitions. The authors achieved 1.95 W with 11.7% efficiency at Q-band (40.6 GHz). At V-band, 1.05 W with 13.6% efficiency (61 GHz) was achieved, and an injection-locked amplifier achieved 20-dB gain, 800 mW and 2-GHz bandwidth with greater than 10% efficiency. Finally, at W-band, the authors achieved 612 mW with 5.7% efficiency (93 GHz) and for long pulse operation 1.08-W peak power at 96 GHz.<>
