Abstract

In this study, we have implemented a PAM(Power Amplifier Module) with 25W output power using by cooperate divider/Combiner circuit in X-band to minimize combine loss on a Al2O3 substrate. The PAM(Power Amplifier Module) is consisted of MMIC and 10way traveling wave divider/Combiner with proposed structure what have showed that 45.2dBm output power, 16dB gain, PAE 26 % and 17dBc@44dBm IMD3 characteristics. This combine/divider structure can be used when multistage passive divider and combiner needs. especially, power amplifier with very compact size.

본 논문은 X대역 고출력증폭기의 전력 결합 손실을 최소화 하기위하여 Al2O3 박막 기판으로 제작한 divider/Combiner 회로를 X-대역의 PAM(Power Amplifier Module)에 적용하여 25W 급 전력증폭기 모듈을 구현하였다. 제작은 MMIC 칩과 수정된 형태의 10way traveling wave divider/Combiner회로를 사용하였으며 제작된 Traveling wave구조의 전력증폭기는 출력전력 45.2dBm, 16dB 이득, PAE 26 % 특성을 얻었으며 IMD3 는 17dBc@44dBm의 특성을 보였다. 본 연구의 divider/Combiner 회로는 다단계 구조의수동 결합기 및 분배기에 사용될 수있으며 협소한 크기의 전력증폭기에 사용될 수 있다.
