DS-9300 Bi-Directional Amplifier


Repeaters Systems | DMR

BDA (Bi-Directional Amplifier) is used to provide bidirectional communication between radio terminals and the base station in order to fit in any kind of environments. 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 multichannel selecting unit, BDA can selectively amplify the signals, ensuring the frequency purity of repeated signals and the stability of output power.
