Description
N 75 Ohm Plug (Male) to N 50 Ohm Jack (Female) Impedance Matching Pad | DC- 2GHz | VSWR 1.25
The ROSNOL MP-N17N25A-2G/144-H4 is a precision impedance matching pad designed to connect N 75Ω plug (male) interfaces with N 50Ω jack (female) systems while maintaining stable RF performance. Operating from DC to 2 GHz, this impedance matching adapter helps minimize mismatch effects between different impedance networks and supports reliable signal transfer in communication equipment, RF test systems, broadcast applications, and measurement environments. Its compact in-line design provides a practical solution for integrating 50-ohm and 75-ohm components within the same RF system.
The matching pad delivers controlled insertion loss of up to 5.7 dB in both 50Ω-to-75Ω and 75Ω-to-50Ω configurations. Performance specifications include VSWR ≤ 1.15 from DC to 0.5 GHz and VSWR ≤ 1.25 from 0.5 GHz to 1 GHz. The design incorporates phosphor bronze and brass center contacts with gold plating, brass bodies with copper-tin-zinc alloy finish, PTFE insulators, and a silicone rubber gasket for dependable electrical and mechanical performance.
Built with a secure screw-lock interface, the ROSNOL MP-N17N25A-2G/144-H4 weighs approximately 0.0526 kg and is designed for long-term operation across temperatures from -55°C to +125°C. It is well suited for telecommunications infrastructure, broadcast systems, RF laboratories, instrumentation platforms, and applications requiring accurate impedance transition between 50-ohm and 75-ohm networks.
