Abstract

A cavity stabilized Gunn oscillator at 24 GHz has been developed with WR-42 waveguide structure by HFSS simulation. The oscillator has been optimized by using a circular iris and cap resonator structure. This oscillator needs 4.5 V DC voltage / 1.2 A current and produces a maximum +21.27 dBm RF power at 24.0675 GHz.

본 논문에서는 WR-42 직각도파관을 이용하여 안정적인 출력을 제공하는 구조를 HFSS 시뮬레이션을 통해 설계하여 24 GHz에서 동작하는 공진기 안정화 Gunn 발진기를 개발하였다. 제작된 Gunn 발진기는 아이리스와 캡구조로 공진기 안정화를 이루기 위한 최적의 구조를 구현하였으며 4.5 V 전압의 1.2 A의 전류를 인가했을 때 24.0675 GHz에서 최고출력 +21.27 dBm을 얻을 수 있었다.
