IF SIGNAL LINE PROCESSING METHOD IN DGS-200 SYSTEM BACKPLANE |
摘要 |
An apparatus for processing an intermediate frequency in a DGS-200 system(Demand Assignment Multiple Access/Single Channel Per Carrier Ground System) backplane is disclosed. The apparatus comprises a number of channel unit(401, 401') for inputting and outputting the intermediate frequency; a radio frequency generating unit for transmitting and receiving the signal and connected to a transmitter and receiver; a transmitting and a receiving intermediate filtering units(407 and 415) for filtering the frequency of the signal which is transmitted and received between the channel unit and the radio frequency generating unit; and a backplane PCB for connecting the channel unit to the intermediate frequency filter unit.
