Detailed Description
The GSM Pico Repeater provides an affordable solution to solve the indoor signal coverage problems due to signal fading and attenuation caused by architecture obstacles. 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 picks up the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Indoor Signal Distribution System to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction. • High system gain • Two signal ports with full duplex design • Linear power amplification to effectively suppress inter-modulation and spurious emission • Unique color LEDs to indicate power supply and signal level of uplink and downlink • Simple installation with external AC/DC adapter SPECIFICATIONS Specification Frequency Range (Customers to Choose) Uplink 890-915 MHz Downlink 935-960MHz Frequency Bandwidth (3dB Bandwidth) 25MHz Gain ≥ 65dB Automatic gain control (Step Attenuation) 31dB @ 1dB/ Step Auto Gain Control 20dB Min. Output Power(Customers to Choose) Spurious Emission ≤ -15dBm/30kHz 9kHz~1GHz: ≤ -36dBm/30kHz 1GHz~12.75GHz: ≤ -30dBm/30kHz Inter-Modulation Attenuation ACPR ≤ -40dBc / 30kHz (measured under rated output power) In-band Ripple ≤ 4dB Voltage Standing Wave Ratio <=1.5 I/O Impedance 50 Ω Noise Figure ≤ 5dB System Delay ≤ 1μs RF Connector SMA-Type (Female) Operating Temperature Operation: - 10°C ~ + 55°C / Storage: -20°C ~ +60°C Power Supply AC 220V±20%, 50/60Hz(AC 220V/ DC5V/3A power adapter) Dimensions 115*150*30 (mm) Weight ≤ 1.5 kg Alarm Monitoring System Alarm for uplink self-oscillation & System Sleep Indication LED Power supply, Run, DW-Alarm, UP-Alarm&(System Sleep)
