Abstract

본 발명은 28㎓대에서도 쓸수 있는 HEMT 및 DRO에 의한 다운컨버터를 만들어 무선(28㎓대) CATV(LMDS)용 다운컨버터의 크기와 가격을 최소화하여도 그 성능은 NTSC 또는 PAL용 오디오 및 비디오를 유선 CATV보다 채널수가 많고 이동에 편리하도록 한 자기공진발진기(DRO)에 의한 28㎓대 다운컨버터를 제공하고자 한 것임.According to the present invention, the downconverter by HEMT and DRO which can be used even in the 28 GHz band is made, and the performance of NTSC or PAL audio and video is reduced even though the size and cost of the down converter for the wireless (28 GHz) CATV (LMDS) are minimized. It aims to provide 28 GHz downconverter by magnetic resonance oscillator (DRO) which has more channels and more convenient than wired CATV.
