Working principle:
Digital Channel Selective UHF Amplifier UHF Repeater


The BS downlink signal enters the BS side duplexer after space transmission. After the amplification through low noise amplifier, the downlink signal will into the digital band selective module which will only chose the bandwidth have set ,the downlink signal will be amplified to some certain power by PA and transferred to MS side service antenna through MS side duplexer. Up till now, the coverage of downlink signal has finished. The theory of uplink cable line is similar with the downlink cable line.
