Coupling Decoupling Network for 50 ohm Cable

Designed for conducted immunity testing on 50 Ω coaxial signal and data communication ports, fully compliant with IEC/EN 61000-4-6 and CISPR 16-1-2 requirements.
Operates over a frequency range of 150 kHz to 230 MHz when used as a Coupling/Decoupling Network (CDN), covering the complete conducted RF immunity test band specified by IEC/EN 61000-4-6.
Specifically intended for coaxial cables with a nominal 50 Ω transmission line impedance, commonly used for RF, data, and telecommunications interfaces.
Provides the required 150 Ω common-mode impedance across the specified frequency range, meeting the impedance and phase characteristics defined by IEC/EN 61000-4-6 and CISPR 16-1-2.
Supports up to 40 V RF input voltage with a maximum current rating of 1 A, allowing stable and controlled injection of RF disturbance levels during immunity testing.
Equipped with 50 Ω BNC connectors for the EUT port, auxiliary equipment port, and RF input port, enabling direct connection of coaxial interfaces without additional adapters.
Incorporates a robust metal enclosure bonded to a conductive stainless steel base plate, providing effective grounding and stable performance during conducted immunity testing.
Individually calibrated with NIST-traceable calibration data and a specified voltage division factor, supporting accurate, repeatable, and traceable setup of immunity test levels.
Used to inject RF common-mode disturbances onto 50 Ω coaxial communication lines while maintaining isolation and uninterrupted signal paths between auxiliary equipment and the EUT.
Ideal for real-world immunity evaluation of products that rely on coaxial data or RF interfaces, such as cable modems, RF transceivers, GPS receivers, satellite communication equipment, test instrumentation, and broadcast or measurement devices.
Enables manufacturers to verify conducted immunity performance of coaxial ports while the product remains operational, ensuring realistic assessment of susceptibility under RF disturbance conditions.
Integrates into complete conducted immunity test systems when used with Com-Power 150 Ω to 50 Ω adapters, 50 Ω terminators, appropriate attenuators or directional couplers, and Com-Power ACS series power amplifiers, providing a comprehensive solution for coaxial-port immunity testing.
