Description
N 50 Ω Plug to N 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-N15N27A-2G/144-H4 impedance matching pad is designed for reliable impedance transition between N 50 Ω plug (male) and N 75 Ω jack (female) interfaces. Supporting operation from DC to 2 GHz, the device maintains a VSWR of ≤ 1.15 from DC to 0.5 GHz and ≤ 1.25 from 0.5 GHz to 1 GHz on both impedance sides. Insertion loss is specified at ≤ 5.7 dB in both transmission directions. The average power rating is 0.7 W at 40 °C, with linear derating to 0 W at 125 °C.The MP-N15N27A-2G/144-H4 utilizes a screw-lock coupling mechanism and features robust mechanical construction. Center contacts are manufactured from phosphor bronze and brass with gold plating over nickel underplating. Connector bodies, coupling nuts, and structural components are constructed from brass with copper–tin–zinc alloy plating. PTFE insulators and a silicone rubber gasket provide stable dielectric performance and mechanical durability.
ROSNOL impedance matching pads are manufactured under ISO 9001-certified quality management systems and are fully compliant with RoHS and REACH requirements. Combining reliable RF performance, high-quality construction, and competitive pricing, ROSNOL products serve as effective alternatives to impedance matching solutions from major European and American manufacturers. Customization services are available to support specific RF interconnect requirements.
