Product Description.
The DH7 Signal Booster Series are FPGA based Digital Channel Selective signal boosters that
operates in the downlink frequency of 763-775MHz and in the uplink frequency of 793-805MHz for
United States. For Canada it operates in the downlink frequency of 768-776MHz and in the uplink
frequency of 798-806MHz.
For operations in the Upper 700 MHz PS-BB spectrum(758-768 MHz and the 788-798 MHz bands)
the TX filter shall be set to:
-Downlink Start Frequency shall be greater than 763 MHz
-Downlink End Frequency shall be less than 768 MHz
-Uplink Start Frequency shall be greater than 793 MHz
-Uplink End Frequency shall be less than 798 MHz
This Signal boosters extends the radio coverage into areas inside the Base Station range where
propagation losses prevent reliable communication.
The system receives the UL signal though a Donor antenna to be amplified, filtered and re-radiated
through the Service antennas. The DL 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 and BW 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.
