LOW BAND HIGH BAND AND MODEM FREQUENCY DIPLEXER ON THE COAXIAL CABLE
摘要
A low-band/high-band modem frequency separator on a coaxial cable is provided to guarantee high-quality signal transmission and maximize productivity. A low-band/high-band modem frequency separator on a coaxial cable comprises a high-band terminal(10) for transmitting high-band signals, a low-band terminal(20) for transmitting low-band signals and a mixing terminal(30) for transmitting a mixed signal in which the high-band signal and low-band signal are mixed. A low pass filter(40) is installed between the mixing terminal and the low-band terminal to pass only the low-band signal as blocking the high-band signal. Between the mixing terminal and the high-band terminal, a high pass filter(50) and a duplexer(60) for dividing the high-band signal inputted through the high pass filter into a PCS/WCDMA frequency band and an FSK modem frequency band to transmit the divided signals are installed.
