Abstract

We report on a high performance 94 GHz MMIC resistive mixer using 70-nm metamorphic high electron mobility transistor (MHEMT) and micro-machined W-band ring coupler. A novel 3-dimensional structure of resistive mixer was proposed in this work, and the ring coupler with the surface micro-machined dielectric-supported air-gap microstrip line (DAMLs) structure was used for high LO-RF isolation. The fabricated mixer showed an excellent LO-RF isolation of -29.3 dB and a low conversion loss of 8.9 dB at 94 GHz. To our knowledge, compared to previously reported W-band mixers, the proposed MHEMT-based resistive mixer using micro-machined ring coupler has shown superior LO-RF isolation as well as similar conversion loss.

본 논문에서는 70-nm metamorphic high electron mobility transistor (MHEMT)와 W-band 마이크로 머시닝 링 커플러를 이용하여 낮은 변환손실 및 높은 격리특성의 94 GHz MMIC 믹서를 설계 및 제작하였다. 놀은 LO-RF 격리도 특성을 얻기 위하여 마이크로 머시닝 링 커플러를 사용한 새로운 3차원 구조의 resistive 믹서 구조를 제안하였다. 제작된 93 GHz MMIC 믹서는 94 GHz에서 8.9 dB의 낮은 변환 손실과 29.3 dB의 높은 LO-RF 격리돈 특성을 나타내었다. 본 논문에서 제안된 믹서는 기존의 보고된 W-band 대역 믹서와 비교하여 양호한 변환 손실 뿐 만 아니라 우수한 LO-RF 격리도 특성을 나타내었다.
