Abstract: A practical method for designing microwave dielectric resonator is proposed. It can conveniently be used with sufficiently high accuracy for engineering applications (calculated resonate frequency error is less than ±1.5%).
A compact, low cost, highly stabilized 11.48 GⅡz Gunn oscillator using one kind of China-made dielectric resonator is described in detail. The frequency drift is less than ±0.45 MHz for a-20-+50℃ temperature range, better than that of a stabilized Gunn oseillator using conventional bulky and high cost Invar cavity. This oscillator can widely be used as a local oscillator in 12 GHz home TV receiver for satellite-relayed programs.
