Abstract

In this paper, we proposed the wireless communication system using millimeter-wave envelope detector. The sub-harmonic mixer based on schottky barrier diode was used in the transmitter. The receiver was used millimeter-wave envelope detector. The transmitter was composed of schottky diode sub-harmonic mixer, frequency tripler, and horn antenna. The receiver was composed of horn antenna, millimeter-wave envelope detector, low pass filter, base band amplifier, and limiting amplifier. At 1.485 Gbps and 300 GHz, the eye-diagram showed a very good performance as measured by the error free. Communication distance is reduced compared to the heterodyne receiver, but compact and lightweight is possible.

본 논문에서는 밀리미터파 포락선 검파기를 이용한 무선통신시스템을 제안하였다. 송신기는 쇼트키 다이오드 기반의 서브 하모닉 믹서를 이용하였으며, 수신기는 밀리미터파 포락선 검파기를 이용하였다. 송신기는 쇼트키 다이오드 서브 하모닉 믹서, 주파수 3배기, 혼안테나로 구성되며, 수신기는 혼안테나, 밀리미터파 포락선 검파기, 저역통과필터, 베이스 밴드 증폭기, 리미팅 증폭기로 구성된다. 1.485 Gbps, 300 GHz에서 아이 다이어그램 (eye-diagram) 측정 결과 에러 프리 (error-free)로 아주 좋은 성능을 보였다. 헤테로다인 수신기에 비해 통신 거리는 줄었으나, 소형 경량화 제작이 가능하다.
