Product Description

The TDD-LTE RF BDA(Bi-Directional Amplifier) is designed to provide a more cost-effective solution than adding a new Base Station (BTS) to improve signal coverage and communication quality in TDD-TLE system. And its easy installation and maintenance can help carrier get fast return.

The BDA is working as a relay between the BTS and mobile terminals. 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 radio network signal is also amplified and retransmitted to the BTS via the opposite direction.

Feature

1. Aluminum-alloy casing with IP65 protection for high resistance to dust, water and corrosion.

2. Supporting TDD-LTE230/TDD-LTE1800 system.

3. Low interference to BTS by adopting linear amplifier with high gain and low noise.

4. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink.

5. RJ45 port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise BDA’s working status and download operational parameters to the BDA Via Ethernet or LAN.

Application

To expand signal coverage or enhance signal blind area where radio network signal is weak or unavailable.

Wireless broadband access technology used in power system
