Description

This is a common-mode current choke (CMCC) KIT for your project. You can select between 50 or 75 Ohm version and coax with open ends or with connector at one side. These CMCC is designed for RX but could be used also for TRX with the power up to 250W. KIT comes also with the holder.


Applications:

  • CMCC for RX antennas
  • Coax cable balun 1:1
  • TRX CMCC up to 250 W
  • Active antenna coax cable isolator

Parameters

  • Frequency range: DC ~ 100 MHz
  • Isolation: typ. 34 dB @ 0.5 MHz, 40 dB @ 2 MHz, 30 dB @ 7 MHz, 23 dB @ 28 MHz
  • Insertion loss: typ. 0.11 dB @ 14 MHz, 0.16 dB @ 28 MHz
  • Impedance 50 or 75 Ohm
  • Coax cable: PTFE RG316 or RG179
  • Cores: 3 pcs QRO-T25
  • Holder with one hole for screw
