5watts Outdoor 1800MHz Signal Repeater Waterproof
Outdoor Repeater DCS1800mhz Network Output 5wattsThe DCS1800mhz RF Repeater is designed to provide a more cost –effective solution than adding a new base transceiver Station(BTS) to improve signal coverage and communication quality in GSM system .And its easy installation and maintenance can help carrier get fast return.The Repeater is working as a relay between the BTS and Mobiles ,it receivers the low-power signal from BTS via the Donor Antenna, Linearly amplifies the signal and then retransmits it via the coverage Antenna to the weak/blind coverage area , And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.Features 1.Aluminum-alloy casing with PI65 protection has high resistance to dust, water and corroding;2.No interference to BTS by adopting linear amplifier with high gain and low noise;3.Adoption filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink;4.USB port provides a link a notebook for local supervision or to the build-in wireless modem to communicate with the NMS )network Management System)that can remotely supervise repeater’s working status and download operational parameters to the repeater Applications To expand signal coverage or fill signal blink area where signal is weak or unavailable Outdoor :Airports ,tourism regions, folf courses, tunnels, factories ,mining districts ,villages ;Indoor :Hotels ,exhibition centers ,basements ,shipping malls , offices ,parking lots ;SpecificationFrequencyTX: 880 ~ 915 MHzRX: 925 ~ 960 MHzOutput powerTX: 35dBm±2dBmRX: 37dBm±2dBmALC controlWhen in max output power, if increased less10dB input Level, the variation of the output power can be controlled within 2dB , When in max output power, if increased over10dB input Level, the variation of the output power can be controlled within 2dB or shut down repeaterGain85±2dBGain control range≥30dBGain control step and errorGain control step：1dBError range：0～10dB, error ≤±1dB；10～20dB ,error≤±1dB；≥20dB, error≤±1.5dBRipple in band≤2.0dB/3.84MHz（peak value）,Ripple in band≤4.0dBFrequency error≤±0.01ppmSpectral emissionMeet 3GPP TS 25.106 demandACRRMeet 3GPP TS 25.106 demandSpurious emissionMeet 3GPP TS 25.106 demandOutput intermodulationMeet 3GPP TS 25.106 demandVector range errorEVM≤12.5%PCDE≤-35dBNoise figure≤6.0dBInsulation test and prevent self-excitationSupportTime delay≤5.0usVSWR≤2.2Ripple out of band2.7MHz≤f_offset≤3.5MHz≤70dB3.5MHz≤f_offset≤7.5MHz≤70dB7.5MHz≤f_offset≤12.5MHz≤45dB12.5MHz≤f_offset≤35dB
