| Abstract: | The design method of a dielectric resonator oscillator (DRO)and the stabilized frequency function of a high Q dielectric resonator(DR)are introduced in this paper.Then a microstrip Gunn-effectoscillator is designed , analyzed and constructed with frequency being stabilized using a high Q ceramic DR. The exporimental results and curves are given. At the end of this poper,the experimental results areanalyzed,and some improved measures are discussed. As a local oscillator,the DRO is applied to X Bandfront-end receivers.It is a satisfactory local oscillator with high performance. |
