초록

본 논문에서는 펄스압축 된 X-대역 마이크로파 신호를 60와트의 출력전력과 30%이상의 전력부가효율(PAE)으로 증폭시키는 반도체증폭기(SSPA)를 구현에 대하여 논의하였다. 구현된 60W의 SSPA는 케스케이드 결합 증폭기로 설계하였고 케스케이드(cascade) 결합 증폭기는 내부정합된 GaAs FET를 3단으로 구동증폭기를 설계하였으며 주 전력증폭단은 내부정합된 GaN HEMT(High Electron Mobility Transistor)로 설계하였다. 구현된 SSPA는 주파수 범위 $9.41{\pm}0.03GHz$, 펄스 주기 1ms, 펄스폭 100us, 듀티사이클 10% 조건에서 전체 이득 37dB 이상, 48dBm(60W)의 출력전력의 성능을 나타내었어 구현된 SSPA는 펄스압축기술을 이용한 디지털 선박용 레이다에 적용할 수 있다.

In this paper, An X-band solid state power amplifier(SSPA) for pulse compressed microwave signal with 60Watt power and power added efficiency(PAE) above 30% is described. Designed 60Watt high power amplifier(HPA) was implemented by cascade coupled amplifiers, and it is consisted on three stage drive amplifiers with internally matched GaAs FET and one stage main power amplifier with an internally matched GaN HEMT. The designed SSPA has performance with more than total power gain 37dB and output power 48dBm(60-W) in condition of frequency range $9.41{\pm}0.03GHz$, pulse period width under 1ms and duty cycle under 10%. The implemented SSPA can apply to high quality digital marine radar applications with pulse compression technique.
