Product Name: 23dBm GSM900MHz 1800MHz 2g 3G 4G Dual Band Cell Phone Signal Booster (GW-23GD-asm) Model NO.: GW-23GD-asm Condition: New Certification: ISO, RoHS, CE Transmission Medium: Wireless Type: Signal Repeater Max Gain: 75dB: Max Output: 23dBm Trademark: Greetwin Transport Package: Neutral Packing Specification: CE, RoHS Origin: Shenzhen HS Code: 8543709200 Product Description 23dBm GSM900MHz LTE 1800MHz 2G 3G 4G Dual Band Cell Phone Signal Booster (GW-23GD-asm)Model: GW-23GD-asmIndoor Pico Repeater (Signal Booster) series is an ideal solution for small/medium businesses and home users looking to enhance indoor wireless connectivity. It is connected via coaxial cable to Donor Antenna and Service Antenna, Donor Antenna is placed outside the building where it has easy access to a BTS signal, and the Service Antenna is placed in the building where it can extend radio coverage to the blind area.Standard Package:1) AC90-264V, DC9V/5A power supply adapter 1PCS2) AC power cord (EU/US/UK/SA/China standard, etc) 1PCS3) Installation kit 1PCS4) User manual 1PCSRecommended Accessories:1)Donor antenna: Log Periodic Antenna (9dBi@806-960/1710-2700MHz)2)Service antenna: Omni Ceiling Antenna (3dBi@806-960/1710-2700MHz)3)5D-FB coaxial cable with connecter (Cable length optional)Application:To expand signal coverage of fill signal blind area where signal is weak or unavailable.Indoor: Hotels, Home, basements, Shopping Malls, Offices, Parking Lots, etc.Frequency RangeUplinkDownlinkGSM900+DCS1800890-915/1710-1785MHz935-960/1805-1880MHzGain70dB±2dB75dB±2dBOutput Power20dBm±2dBm23dBm±2dBmBand widthWide BandManual Gain Control31dB / 1dB StepAutomatic Gain Control>20dBRipple in-band≤8dBReturn loss≤ -10dBNoise Figure≤ 6dBSpurious Emission&Intermodulation9KHz~1GHz≤ -36dBm1~12.75GHz≤ -30dBmTime Delay≤ 1.5 μsFrequency stability≤ 0.01ppmMTBF> 50000 hoursPower SupplyAC100-240V,DC9V/5APower LEDPower indicatorAlarm LEDRedAutoexcitation or High PowerGreenStandardMechanical SpecificationRF ConnectorN-FemaleSwitchPower SwitchManual Gain Control SwitchCoolingHeatsink Convection coolingImpedance50 ohmHumidity< 90%Operating Temperature-10°C~55°CEnvironment ConditionsIP40Size250mm*170mm*53mmWeight< 3.5KgApplication Diagram:Features:Smart Function,Intelligent mode settingCompare to the worldwide repeater brand, has a smart function called which can be activated via the front panel. This smart function can prevent UL interference and self-oscillation caused by insufficient isolation between donor and service antennas, and also setup parameters and keep optimal condition automatically; the only thing for users is just activating this function by front panel.Notify that the users can't adjust by manual setting when smart function is initiated.For example,(To set attenuation for the uplink)Step 1:PressSELECTtill the indicator stops at uplink.Step 2:PressSTOREand LED monitor starts blinking.Step 3:Press"+", "-"to an intended gain value.Step 4:PressSTOREto set the value and the LED stop blinking andshowing the gain value at the moment, the process is done.Company Information
