37dbm GSM and 3G Dual Band Booster/Repeater(DE37-GW)

37dbm GSM and 3G Dual Band Booster/Repeater (DE37-GW)


     The DE20-GW dual system repeater is to support
any two mobile systems GSM and 3G to help end users to improve mobile
signals for better signal coverage. It is designed to support coverage
area up to 4000 square meters with proper engineering. Below are the
main features:
1. Intermediate SAW filter technology for very sharp out of band
rejection to amplify only specific operators’ signals and reject al l
the others.
2. Manual gain control (MGC) available for both uplink and down link to
adjust the gain value for proper coverage during installation or
3. To maintain safe and specific output signal levels and give alarms
on self-oscillation, the repeater has built-in AGC and ALC circuits,
which can automatically control the gain of the repeater depending upon
the strength of input signals.
4. Auto shut off design available for both uplink and downlink to avoid
serious interference to network effectively when the repeater is in
deep self-oscillation or very strong input power.
 5. Support one to four sub bands for each system.
