Abstract

In this paper, we have designed and fabricated an BWLL MMIC amplifier using GaAs PHEMT devices. We have optimized power divider/combiner size for small size of MMIC amplifier Using 0.2 ${\mu}$m AIGaAs/lnGaAs/GaAs PHEMT devices, the two stave MMIC amplifier has demonstrated a S$_{21}$ gain of 8.7 ㏈ with input/output return losses of lower than -10 ㏈ at 26.7 GHz. The size of this chip is 4.11 ${\times}$ 2.66 $\textrm{mm}^2$.

본 논문에서는 전자선 묘화 장비를 이용하여 게이트 길이가 0.2 $\mu$m인 PHEMT를 제작하여 특성을 분석하고, 임피던스정합 및 바이어스 회로를 위한 수동소자 라이브러리를 작성하여 BWLL용 MMIC 증폭기를 설계 및 제작하였다. 제작된 2단 MMIC 증폭기는 26.7 GHz에서 8.7 ㏈의 소신호 이득 및 -10 ㏈ 이하의 입 .출력 반사 계수를 얻었다. 제작된 2단 MMIC 증폭기의 팁 크기는 4.11$\times$2.66 $\textrm{mm}^2$ 이다.
