Description

Common-mode choke coils work as a simple wire against differential mode current (signal), while they work as an inductor against common-mode current (noise).


Using

  • Common-mode filter for coax cable
  • RX antennas, active antennas etc.

Main functions

  • Common-mode current insulator
    • High current insulation
    • Impedance 50 or 75 Ohm
  • High quality PTFE coax cable
  • High quality connectors
  • Low insertion loss
  • IP56 box - recommended to protect it against water
  • Feeder size 100x100 mm
  • ASSEMBLED AND TESTED VERSION

Parameters

  • Insertion loss lower than 0.2 dB (at 50 MHz)
  • Common-mode isolation better than 30 dB (7 MHz and lower)
  • RF power up to 100 W
