Abstract

In this paper, we present a design for solid-state radar SSPA with sequential bias. We apply to variable extension pulse generator to eliminate signal distortion which is caused by bias rising/falling delay of power amplifier. There is an optimum impedance matching circuit to have high efficiency of GaN-power device by measuring microwave characteristics through load-pull method. The designed SSPA is consisted of pre-amplifier, drive-amplifier and main-amplifier as a three stages to apply for X-Band solid-state radar. Thereby we made a 200W SSPA which has output pulse maximum power shows 53.67dBm and its average power is 52.85dBm. The optimum design of transceiver module for solid-state pulse compression radar which is presented in this dissertation, it can be available to miniaturize and to improve the radar performances through additional research for digital radar from now on.

본 논문에서는 순차 바이어스를 이용한 반도체 레이더용 SSPA를 설계 하였다. 전력증폭기의 상승/하강 바이어스 지연에 의해 발생되는 신호의 왜곡을 제거하기 위하여 가변확장 펄스 생성기를 적용하였다. 최적화된 임피던스 매칭회로는 GaN-전력 소자의 높은 효율을 갖기 위하여 로드-풀 방식을 통한 마이크로파 특성 측정으로 설계되었다. 설계된 SSPA는 X밴드 반도체 레이더에 적용하기 위하여 전치 증폭기, 구동 증폭기 그리고 주 증폭기의 3개의 단으로 구성되었다. 그 결과로 200W 출력 펄스 최대 53.67dBm을 가지고 평균 52.85dBm의 SSPA를 만들 수 있었다. 본 논문에 제시된 반도체 펄스 압축 레이더 트랜시버 모듈의 최적화 설계는 추가적인 디지털 레이더에 대한 연구를 통해 소형화와 동작향상이 가능하다.
