Broadband Bi-Directional RF Amplifier

9501-BDA3I3J159
380 - 420 MHz / 15dBm

bidirectional Amplifier

The BDA3I3J159 (SKU # 9501) is suitable for long coax cable loss elimination and providing amplification in both directions. This unit offers fully symmetrical bandwidth without any frequency sensitivity.  Performance is achieved by using proprietary cancellation techniques and without diplexers.  Each direction has a dedicated amplifier and wideband band pass filter that can be set to customer needs.  The gain can be setup to 20dB for each direction for a total of 40dB in both directions when operating into low return loss 50 loads. For cables loss greater than 20dB or different frequency bands consult us for the most effective solution.

  • Fully symmetrical bandwidth, No diplexers design.
  • Solid-state MMIC Amp linear design
  • Instantaneous broadband
  • Small and lightweight
  • Suitable for all types of Analog and Digital Signals
  • 50 Ohm Input/Output impedance
  • High reliability and ruggedness
