28GHZ Band Down Converter by Self Resonant Oscillator

摘要

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.
