TBCMC-1

RF Common Mode Choke

The Tekbox TBCMC-1 is a general-purpose RF common mode choke designed to attenuate ground loop currents and improve measurement accuracy in RF impedance setups, especially those based on the shunt method. Its symmetric design and wide frequency performance make it ideal for EMC and RF test environments.

Features

Key capabilities and advantages

  • General-purpose RF common mode choke for reducing unwanted ground loop noise in test setups.
  • Wide frequency range: operates from 1 Hz up to 1 GHz (recommended up to 500 MHz).
  • Excellent for measurement integrity.
  • High common mode rejection across broad frequency bands for effective noise suppression.
  • 50 Ω N-female connectors for easy integration with RF and EMC measurement equipment.
  • Compact and lightweight design suitable for lab benches and RF test setups.
