Product Description
27dbm 85db GSM DCS WCDMA digital tri band signal repeater
1.Profile
ET-DRDWL27TI-F model can support 2G GSM,UMTS,3G WCDMA and 4G LTE system at same time on 1800MHz 2100MHz and 2600MHz, use digital IF SAW filter to support up to 4 sub band with 0.2-25MHz adjustable sub band width on each band.
1.1Features
1.Use the digital IF SAW filters, the out of band rejection is very good and comply with ETSI,3GPP and 3GPP2 standards.
2.support up to 4 sub band with 0.2-25MHz adjustable or 1 sub band with 0.2-40MHz and 3 sub band with 0.2-25MHz.
3.Built-in AGC and ALC circuits, which can automatically control the gain of the repeater depending upon the strength of input signals and digital display current Gain.
4.31dB MGC (Manual gain control) for whole band:1dB/one step available for both uplink and downlink and 25dB MGC for each sub band separately.
5.Monitor by PC monitor software or Cloud monitor system.
It can be local and remote monitored and controlled by our own software which is based on SQL data and server. local monitored and controlled by USB port
Remote monitored and controlled via 2G,3G,4G data or Ethernet
More parameters can be monitor by software, such as DL PA temperature, Input power, DL output power, DL actual Gain, AGC Value, etc
It also has many alarms, such as input power over or low alarm, output power over or low alarm, DL PA over temperature alarm, self-oscillation alarm etc.
It also support to set DL ATT, UL ATT, PA power on/off and change the alarm threshold by Monitor software.
6.Limit the output power available for both uplink and downlink to avoid deep self-oscillations from jamming the towers, saving your trouble from operators.
