Abstract

2-port stable bipolar transistor oscillator is realized in S band. Oscillator is fabricated by using a highly frequency stabilized 3 identical dielectric resonators and negative resistance is found by means of 3 ports scattering parameters. In this paper, using dielectric resonators as a feedback element. We obtained maximum output 14dBm. 10dBm from collector and base respectively.

無條件 安定인 超高周波用 바이폴라 트랜지스터를 使用하여 S 밴드에서의 發振器를 具現하여 보았다. 發振器는 周波數安定한 3個의 同一한 誘電體 共振器를 利用하여 製作되었으며 負性 抵抗은 3포트 散亂係數(3-Ports Scattering Parameters) 方法으로 求하였다. 本 論文에서는 誘電體 共振器를 궤환素子로 使用하여 콜렉터, 베이스에서 各各 41dBm, 10dmB의 最大出力을 얻을 수 있었다.
