다중 빔 위성중계기 부품중의 하나인 MSM(Microwave Switch Matrix)에 필요한 SPST 스위치 MMIC를 설계 및 제작하였다. 설계된 스위치 MMIC는 3㎓ 대역에서 동작하며, 새로운 구조를 채택하여 기존의 FET 스위치보다 전력 특성과 격리도를 개선하였으며, 스위치의 On/Off 상태에서의 입출력 반사손실 특성이 우수하다. MMIC는 0.15um GaAs pHEMT 공정으로 제작되었으며, 3~4㎓ 대역에서 2.0㏈ 이하의 삽입손실과, 63㏈ 이상의 격리도 성능을 가지는 것으로 측정되었다. 또한 사용된 단위 pHEMT 소자가 0.2㎜ Gate Width 임에도 불구하고 32㏈m 이상의 OIP3 특성을 가지고 있는 것으로 측정되었으며, 이 결과는 기존의 발표된 FET 스위치에 비해 높은 전력 특성이다.
