Simple Stabilizing Method for Solid-State Microwave Oscillators (Short Papers)

In the microwave solid-state oscillators using bulk effect and avalanche diodes, high dielectric constant ceramics have been used as a temperature compensator and excellent temperature stability is obtained. An X-band avalanche diode oscillator is tested over a wide temperature range. The frequency drift is improved to be less than +30 kHz//spl deg/C. Additional advantages of this technique are compact size and low cost.
