CDS8E-694/3800
8dB Directional Coupler

Rev : A | Rev date : 15 Nov 2025
RFS CDS**E series Directional Coupler has been designed for intdoor applications covering 694 to 3800MHz. Units couple off a defined fraction of signal from 6 to 30 dB with minimal reflections or loss. The frequency range allows use with antennas and leaky cable systems and in wireless base stations. With minimal solder joints, the dissipative loss has been minimized and reliability enhanced.

Features / Benefits

  • 8 dB coupling value
  • Low insertion loss
  • High power handling
  • Small size, Low weight
  • N-female connectors
  • Low PIM
