Pulsed Double-Drift Silicon IMPATT Diodes and Their Application
1974
The performance and application of double-drift silicon IMPATT diodes designed for pulsed operation at frequencies between 8.5 and 18 GHz are described. Peak pulse powers greater than 18 W at 10 GHz and 13.5 W at 16.5 GHz were obtained for 800-ns pulses at a 25-percent duty cycle with the average junction-temperature, rise limited to 200/spl deg/C. Conversion efficiencies were between 11 and 13.7 percent. The microwave cavity and pulsed bias circuitry are described in detail.
