Product Description

20dBm 70dB GSM 900MHz Band Selective Cellular Amplifier
Certification CE0700 and RoHS

Profile

ET-BSG20S-F model can support GSM  Band selective system. The bandwidth can be customized in the frequency range.

Features

1.Elegant and Compact design,good isolation and heat dissipation for long time operation.

2.Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals.

3.31dB MGC(Manual gain control) 1dB one step available for both uplink and downlink to adjust the gain value for proper coverage during installation or maintenance.

4.Limit output power for both uplink and downlink to avoid deep self-oscillations from interference BTS.

5.Wide input power range,low power consumption.

6.With good IMD3,it can have more antennas for covering without affect towers.

7.High linear design,the intermodulation and and spuriousness are suppressed effectively.
