Description
N 50 Ω Plug to BNC 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-N15B27A-2G/H44-H4 impedance matching pad is designed to enable accurate impedance transition between N 50 Ω plug (male) and BNC 75 Ω jack (female) interfaces. Supporting operation from DC to 2 GHz, the device delivers stable RF performance with a VSWR of ≤ 1.15 on the 50 Ω side and ≤ 1.25 on the 75 Ω side. Insertion loss is specified at 5.7 dB in both transmission directions, with an average power rating of 1 W.The MP-N15B27A-2G/H44-H4 employs a screw-lock coupling mechanism on the N side and a bayonet-lock coupling mechanism on the BNC side to ensure secure and repeatable connections. Center contacts are fabricated from phosphor bronze with gold plating over nickel underplating. Connector bodies, coupling nuts, and hardware are constructed from brass copper–tin–zinc alloy, while PTFE insulators and a silicone rubber gasket support stable mechanical and electrical performance.
ROSNOL impedance matching pads are manufactured under ISO 9001-certified quality systems and fully comply with RoHS and REACH requirements. Combining reliable performance, high quality, and cost-effective pricing, ROSNOL products serve as dependable alternatives to impedance matching solutions from major European and American RF brands. Customization services are available to support specific mechanical, material, and application requirements.
