5GNR TDD-3.8GHz Band Selective RF Repeater
Model: AT50A37B1
Frequency Range: 3700 ~ 3800MHz
Technology: 5GNR
Output Power: 37±2dBm
Maximum Gain: 85±3dB
Product Description
The 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 Radio 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 receives 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.
Feature
1. Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrosion.
2. Low interference to BTS by adopting linear amplifier with high gain and low noise.
3. Built-in 5G Dynamic TDD Sync Detection Module, automatic completion of 5G wireless network cell search and wireless signaling processing.
4. RJ45 port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise Repeater’s working status and download operational parameters to the Repeater Via Ethernet or LAN.
Application
 | To expand signal coverage or fill signal blind area where signal is weak or unavailable. 1. Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, … 2. Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, … |
