TS-9200 BDA

Bi-Directional Amplifier

Bi-Directional Amplifier

As a Bi-Directional Amplifier (BDA), TS-9200 BDA can selectively amplify the signals, ensuring the frequency purity of repeated signals and the stability of output power. It has excellent compatibility and is now widely used in trunking communication systems such as TETRA, iDEN, MPT-1327, LTR, APCO25 as well as conventional communication system.

 As a Bi-Directional Amplifier (BDA), TS-9200 is used to provide bidirectional communication between terminal radios and the base station in order to fit in any kind of environment. It can be used outdoors to extend the coverage range of base station, making communication services available in areas with no or weak signals. Additionally, it can be used indoors as the signal source to improve signal strength. With a multi-channel selecting unit, TS-9200 BDA can selectively amplify the signals, ensuring the frequency purity of repeated signals and the stability of output power. It has excellent compatibility and is now widely used in trunking communication systems such as TETRA, iDEN, MPT-1327, LTR, APCO25 as well as conventional communication system.

BDA Type:

·Integrated RF BDA

·Fiber Optical BDA(Coupling by air)

·Fiber Optical BDA(Coupling directly)

Product Highlights

·With modularized design, easy for maintenance;

·Software remote monitoring (GSM、Ethernet(SNMP) 、serial port), easy for maintenance and management.

·SDR (Software Defination Radio) Technology, filtering irrelative and ensuring stable output power & clean spectrum output.

·Function of Channel Switch. With this functions, the channel will automatically be shut down if there is no call in the coverage, which can strongly reduce the impact of base stations.

·Dustproof, moistureproof & waterproof, with low requirements on installation environment;

·With high-linearity power amplifier and high-rejection duplexer, capable of rejecting intermodulation and spurious signals;

Application Examples

·Coverage Solution for Tunnels Signals are strongly shielded in long and narrow tunnels due to barriers such as mountains. As a result, there is almost no signal except the entrance and exit. BDA would throw this problem away.

·Coverage Solution for Roads and Railways

Install BDAs between base stations of trunking system along highways, railways or rivers, and users will enjoy the following benefits: coverage range extension of trunking system; the reduction of base station number and frequency resource occupation; significant cut of system construction cost and winning of a cost-effective zonal coverage solution with high performance.

·Coverage Solution for Indoor Areas

Most trunking systems adopt the large coverage system. As a result, the signals are weak when getting to the indoor area due to the attenuation such as space loss and penetration loss. This is why signal blind areas or poor communication quality occur in the lower floors, basements, Mine and elevators of high-rise buildings. In these cases, BDA is the best solution thanks to its ability to improve signal strength and ensure communication quality. 

·Coverage Solution for Outskirts Areas 

In suburbs and remote town areas, BDA is the best coverage solution, not only for its affordability and easy installation, but also for its functions (equal to a small base station).

·Coverage Solution for Congested Residential Areas

In congested residential areas, buildings vary in height and the space size between two buildings is small with complex electromagnetic environment. This may cause the signal to attenuate quickly. Therefore, low coverage rate and poor communication quality result. Luckily, these problems can be eliminated by using BDAs.
