Product Description
outdoor tri band digital repeater for extend cellular signal coverage
1.Profile
ET-DREDW37TI-F model can support GSM,UMTS,WCDMA and LTE system at same time on 900MHz,1800MHz and 2100MHz, 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.Limit the output power available for both uplink and downlink to avoid deep self-oscillations from jamming the towers, saving your trouble from operators.
6.Easily adjust the sub band and the channels by software to adapt to the operators' requirement without any change on the hardware, just need input the start frequency and stop frequency for each sub band.
7.LCD display Gain and actual output power for whole band and support to set the Gain by key.
