Overcoming Communication Challenges

What are Bi-Directional Amplifiers? (BDAs)

A BDA (Bi–Directional Amplifier) is an RF signal booster used to improve radio communications in situations where radio signal levels are degraded due to obstacles in the radio path.

This might be in tunnels, high rise buildings and underground car parks where their construction can prevent the signals from a source reaching the users in these areas.

They are available in a number of variants to suit the communications situation, this includes integrated and distributed configurations and band and channel select options.

DS–9300 Highlights

  • Easy to deploy: DS–9300 Is small, light–weight, with flexible mounting options
  • UHF: DS–9300 supports 400–470MHz
  • Excellent out-of-band rejection: The DS–9300 starts signal rejection from 50KHz, which provides excellent rejection of out-of-band signals, which enhances coverage and voice quality
  • Excellent intermodulation attenuation: for the DS–9300, 8 carriers deliver –45dBc which is effective in eliminating the interference of intermodulation signals. This helps to provide better coverage and voice quality
