Description
BNC 50 Ω Plug to BNC 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-B15B27A-2G/H44-H4 impedance matching pad is designed for impedance transition between BNC 50 Ω plug (male) and BNC 75 Ω jack (female) interfaces. This model supports RF signal transmission from DC to 2 GHz, delivering stable performance with a VSWR of ≤ 1.10 from DC to 1 GHz and ≤ 1.25 from 1 to 2 GHz. Insertion loss is specified at 5.7 dB in both transmission directions, with an average power rating of 1 W.The MP-B15B27A-2G/H44-H4 features bayonet-lock coupling mechanisms on both BNC interfaces to ensure secure and repeatable connections. Center contacts are fabricated from phosphor bronze with gold plating over nickel underplating. Connector bodies and coupling nuts are constructed from brass copper–tin–zinc alloy, while PTFE insulators provide consistent dielectric performance. A silicone rubber gasket enhances mechanical stability during high-frequency operation.
ROSNOL RF impedance matching pads are manufactured under ISO 9001-certified quality systems and fully comply with RoHS and REACH requirements. Offering reliable performance, consistent quality, and cost-effective pricing, ROSNOL products serve as dependable alternatives to impedance matching solutions from leading European and American brands. Customization services for materials, plating, and mechanical design are available to support specialized RF applications.
