Description
BNC 50 Ω Jack to BNC 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-B25B27A-2G/H4-H4 impedance matching pad is designed to provide accurate impedance conversion between BNC 50 Ω jack (female) and BNC 75 Ω jack (female) interfaces. Operating from DC to 2 GHz, the device delivers stable RF performance with a VSWR of ≤ 1.1 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-B25B27A-2G/H4-H4 features bayonet-lock coupling mechanisms on both BNC interfaces to ensure secure and repeatable mating. Center contacts are manufactured from phosphor bronze with gold plating over nickel underplating. Connector bodies are constructed from brass copper–tin–zinc alloy, while PTFE is used as the insulator material to maintain stable dielectric properties.
ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. ROSNOL impedance matching pads offer reliable quality, consistent RF performance, and competitive pricing, making them suitable alternatives to products from leading European and American RF brands. Comprehensive customization services for materials, plating, and mechanical configurations are available upon request.
