초록

본 논문에서는 X-대역 레이더 시스템의 국부 발진기용으로 사용가능한 발진기를 소형화된 헤어핀 공진기를 이용하여 설계한다. 제안하는 헤어핀 공진기는 기존의 헤어핀 구조에서 선로 끝단에 커패시턴스를 증가시켜 소형화하였다. 이 구조는 기존 구조에 비해 크기를 40% 정도로 소형화할 수 있고 위상잡음 특성도 개선하였다. 제안한 헤어핀 공진기를 이용한 발진기는 측정결과 발진주파수는 9.05 GHz, 출력전력이 2.47 dBm, 위상잡음 특성이 -101.4 dBc/Hz이었다. 본 논문에서 제작된 발진기는 소형화 설계가 가능하고 평면형 구조이므로 MMIC 설계에 유리한 장점이 있다.

In this paper, oscillator with compact hairpin resonator is used to design the local oscillator of X-band radar system. The proposed hairpin resonator is minimized by increasing capacitance of line end of conventional one. By this method, size can be minimized about 40% compared with the conventional resonator and also can improve phase noise characteristic. The result of oscillator using proposed hairpin resonator is measured in oscillating frequency of 9.05 GHz, output power of 2.47 dBm, and phase noise of -101.4 dBc/Hz. The fabricated oscillator in this paper can minimize design and it's planar structure makes it easy to design MMIC.
