초록

밀리미터파 대역의 부품 수요가 많아질 것으로 예상되어지는 57~63 GHz 대역의 하향 변환 혼합기를 IHP SiGe 0.25 um 공정을 이용하여 설계 및 제작하였다. 혼합기 RF 단에 크기를 줄인 3D 발룬(balun)을 위치하였으며, 혼합기는 두 개의 평형 혼합기로 구성하고 LO 신호의 억압과 출력단의 이득을 위하여 버퍼(buffer) 증폭기를 위치하였다. 측정 결과, 변환 이득 13.8 dB, $P1dB_{in}$ -17 dBm, 전류 소모는 88 mA의 특성을 나타내었다.

A lot of demand for parts of millimeter wave band, as would be expected 57~63 GHz band down conversion mixer was designed and fabricated using IHP 0.25 um SiGe process. Designed and fabricated mixer was double balanced type and located reduced 3D balun at RF port and buffer amplifier at outport for suppression LO signal and conversion gain. Fabricated mixer measured conversion gain of 13.8 dB, $P1dB_{in}$ -17 dBm and 88 mA of current consumption characteristics, respectively.
