Macom Professional Series

C860 : Macom Series Bi-Directional Combiner


  • Broadband 5-1000MHz
  • Broadcast quality specifications for unparalleled picture quality
  • Built in Return-Path Diplexer
  • Sub-band output port provides high isolation VHF/UHF ingress-free return path for CMTS and remote audio/video application
  • >18dB return loss provides reduced reflections for exceptional digital signal performance
  • Directional coupler design provides improved carrier-to-noise, system performance and picture quality
  • High -50dB port to port isolation provides spurious carrier rejection and minimizes undesired channel interaction, thereby reducing picture distortion
  • Passive design allows bi-directional flexibility for two-way digital and analog requirements
  • Plug-in equalizers and attenuators (included) enable uniform gain and slope system balancing for minimum distortion
  • -20dB test port provides convenient access for headend testing and system monitoring
