UM-0849 4 2. Product Description. The DH4 Signal Booster Series are FPGA based Digital Channel Selective signal boosters that operates in the downlink frequency of 450 - 512MHz and in the uplink frequency of 450 - 512MHz for United States and 450 - 470MHz and in the uplink frequency of 450 - 470MHz for Canada. This Signal boosters extends the radio coverage into areas inside the Base Station range where propagation losses prevent reliable communication. The system receives the DL signal though a Donor antenna to be amplified, filtered and re-radiated through the Service antennas. The UL signal is received by the Service antennas to be amplified, filtered and re-radiated through the Donor antenna back to the Base Station. This way, the system works as a Bidirectional Amplifier. This signal booster is capable of handling 12 carriers in uplink and 12 carrier in downlink. The center frequency of each one of the 12 filters can be tuned via a software interface. The intermediate filtering of this equipment is performed by using FPGA based Digital Signal Processing that, among many, has the following features: • High Selectivity vs Low Delay performance selection. • AGC per channel and per time slot. • Squelch per channel and per time slot. • Integrated Spectrum Analyzer. This Digital Signal Booster has a heavy duty IP67/NEMA4X cabinet for outdoor usage, it is designed to be wall or pole mounted. This Digital Signal Booster is intended to be used in P25Ph1, P25Ph2, TETRA, DMR, Mototrbo and Conventional radio systems.

After that time, the Signal Booster is ready to be connected via USB cable to a computer running Fiplex Control Software (FCS) to be properly configured. Figure 15; USB port location
UM-0849 18 5. Starting Operation BE SURE THAT “TO MOBILE” AND “TO BASE” PORTS ARE PROPERLY LOADED EITHER WITH 50 OHMS DUMMY LOADS, OR RADIATING SYSTEM. 1. Turn on the Digital Signal Booster, connect computer to Signal Booster through USB cable, and run Fiplex Control Software. It is recommend to turn off the power amplifiers. 2. Setup desired channel frequencies. Since Fiplex Signal Booster is channel selective, user has to know what frequencies are used in base station. 3. Turn on UL and DL power amplifiers, and check that any alarm indicator is active.
UM-0849 19 4. Setup desired operating gain using FCS. UL and DL chain are independent, so both values must be set. To set DL band gain is recommended that AGC works around 3 - 6dB in each channel, in this way, maximum output power is achieved. 5. Set up squelch settings. Controls are independent in UL and DL bands. Typical values for UL are -110dBm for squelch threshold. For DL, recommended value for squelch threshold is minimum level received in any active channel minus 10dB. 6. Setup desired filter bandwidth, depending on presence of adjacent channels. In principle, recommended bandwidth filter is 45KHz due to its low delay, but if adjacent signal is detected, narrow filters can be used. Spectrum analyzer of FCS can be used to know rejection to undesired signals. It is recommend that adjacent channels output power be, at least, 10dBc lower than useful carrier. Next figures, shows how integrated spectrum analyzer can help to select bandwidth filters:
