Abstract

In this paper, the Gunn diode mount is experimentally designed for use in a W-band waveguide voltage controlled oscillator(VCO). The role of the Gunn diode mount is to match the low impedance of the Gunn diode to the high impedance of waveguide. Computer simulations of VCO characteristics such as center frequency, frequency tuning range, and output power are carried out for various values of disc diameter, disc height, post diameter, and utilized in the experimental optimization of the Gunn diode mount. The designed VCO shows excellent characteristics; 93.9 GHz center fiequency, 600 MHz frequency tuning range with $2{\%}$ linearity, 16 dBm output power.

본 논문에서는 W-대역 도파관 전압조정발진기에 적용할 수 있는 건 다이오드 마운트를 실험적으로 설계하였다. 건 다이오드 마운트에 의해서 건 다이오드의 낮은 임피던스는 도파관의 높은 임피던스에 정합된다. 건 다이오드 마운트에서 디스크 직경, 디스크 높이, 금속봉 직경에 따른 전압조정 발진기의 중심 주파수, 주파수 조정범위, 출력전력 등 특성 변화 경향을 시뮬레이션에 의해 확인한 후 실험적인 방법으로 최적의 건 다이오드 마운트를 설계하였다. 설계된 전압조정 발진기는 중심 주파수 93.9 GHz, $2{\%}$ 주파수 선형성 범위 600 MHz, 출력전력 16 dBm 등의 우수한 특성을 보였다.
