Abstract
근거리무선통신(Dedicated Short Range Communication, DSRC)은 근거리 영역의 노변장치(Road Side Equipment, RSE)와 차량탑재장치(On-Board Equipment, OBE)와의 고속통신을 수행하는 통신시스템이며, 대부분의 지능형교통시스템 서비스는 근거리무선통신에 의해 제공될 것으로 보인다. 본 논문에서는 근거리무선통신 수신기용 하향믹서를 설계 및 제작하였다. 설계된 하향믹서는 믹서코어 회로와 더불어 RF/LO 입력 정합 회로, RF/LO 입력 발룬 회로와 IF 출력 발룬 회로가 온칩으로 구현되었다. 제작된 하향믹서는 1.9 mm X 1.3 mm의 크기를 가지며, 7.5 dB의 전력변환이득과 -2.5 dBm의 ⅡP3, 46 dB의 LO to RF isolation, 56 dB의 LO to IF isolation, 3.0 V의 공급전압 하에서 21 mA의 전류소모로 측정되었다.
