Product Name: Mobile Signal Booster Repeater Working Frequency: Customizable Noise Floor: IM3: ≤-45dBc Dimensions: 240*164*52mm Weight: 1kg 15dBm WCDMA 2100MHz Built in Antenna Pico Repeater , Mobile Signal Booster   Model: VR-4390-GW   Product Instructions:               The WCDMA Built-in Antenna Pico Repeater/Signal Booster 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 WCDMA system.       The repeater is working as a relay between the BTS and mobile phones. It receives the low-power signal from BTS via the Built-in Donor Antenna, linearly amplifies the signal and then retransmits it via the Built-in Service Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.   Product Features:   Automatic system gain Control (AGC) available. Linear power amplification to effectively suppress inter-modulation and spurious emission. Smart Automatic Level Control (ALC) ensures output level stable and adjustable continuously. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink. Easy Installation and Automatic Operation, ready for use. Applications:   To expand signal coverage or fill signal blind area where GSM and WCDMA signal is weak or unavailable. Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, etc. Technical Specifications:   Items Specifications Working Frequency Uplink 1920-1980MHz Downlink 2110-2170MHz Output power Uplink 10dBm Downlink 15dBm Maximum Gain ( UL and DL ) 45dB ALC ( Automatic Level Control ) >45dB AGC (Automatic Gain Control) 30dB in step of 1dB (Auto) System noise figure 5dB @ max. gain Spurious Emission Mask Comply With 3GPP TS 25.106 Spurious Emission Comply With 3GPP TS 25.106 (Category B) Noise Floor IM3 ≤-45dBc Power supply(customized) 100V-240VAC 50Hz Gain Flatness ≤4dB/3.84MHz Modulation Accuracy ≤12.5% I/O Inter-modulation Comply with 3GPP TS 25.106 Frequency stability ≤0.01ppm Group Delay UL≤1μs Peak Code Domain Error ≤-35dB@Spreadimg Factor 256 Weight 1Kg Size 240*164*52mm   Product Image:
