C23A-4B Series 4 Bands Signal Repeater

Product Features


* All aluminum alloy shell case, better heat dissipation and signal shielding

* Self-oscillation cancellation, auto degrade the gain, when there is insufficient isolation, to cancel the self-oscillation

* Uplink auto stand-by, when there is no mobile users in the coverage area, to minimize the interference to BTS tower

* ALC, auto level control to limit the output power for stable and safe performance

* Linkage between uplink and downlink gain, keeping uplink and downlink balanced.

* Independent LED indicators to show the working status of 4 bands

* MTBF up to 100,000 hours.

     C23A-4B series 4 bands signal repeater is a multi bands signal repeater dedicated to specific places with weak outdoor macro cell signal and small indoor spaces. In many cases, the mobile phones display 1-2 signal bars, but cannot be used normally. This is because the signal from mobile phone cannot be transmitted back to BTS. In response to this situation, Amplitec R&D team increased the uplink output power of C23A-4B repeater to 23dBm, plus the power of outdoor antenna, the total radiation power can reach 2W, which greatly increases the transmission distance of the mobile phone's to 10 KM. Amplitec R&D team adopted EDA digital simulation technique & unique 50Ω impedance matching wiring process in circuit design. The core components are all originated from famous international brands, ensuring the stable and excellent performance of the repeater.

     This series of signal repeaters supports the combination options of commonly used frequency bands such as B1, B2, B3, B4, B5, B7, B8, B20, B28 to be 4 bands including 1 low frequency plus 3 high frequency. There are multiple model options to work to enhance 2G, 3G, 4G, 5G signal coverage in various regions.
