Add on satellite receiver unit two way interchange having transmission block receiving coaxial band input/offsetting frequency /amplifying/transmitter with second input/output connected first connection via rejection filter

摘要

The radio wave transmission block (102) has an input/output (150) connector for a coaxial cable input (300) carrying the intermediate frequency. There is a frequency offset producing the transmission frequency, then amplifying the signal and transmitting it. There is a second input/output (152) connected to the first connection by a band rejection filter (153) rejecting the transmitter intermediate band.
