2. Product Description.
The DHS40-HG-SCH-2 Signal Amplifier are single channel amplifiers that operates in the downlink frequency
of 851-869MHz for United States.
This Signal Amplifiers amplifies the RF signal of a Base Station or Transmitter equipment without the need of
a previous amplification (driver, power amplifier).
The system receives the BTS or Transmitter signal to be amplified, filters, amplifies and re-radiates through
the connected antenna/s.
This signal amplifier is capable of handling one single channel, narrow band. It is not intended to be used as a
multiple carrier signal amplification. The channel BW and frequency position can be tuned via a software
interface.
The intermediate filtering of this equipment is performed using FPGA filtering technology and, among many, it
has the following features:
- High Selectivity.
- Channel filter BW selection.
This Signal Amplifier has a compact heavy duty 2 RU cabinet for indoor usage.
