Description
BNC 50 Ω Plug to F 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-B15F27A-2G/H44-H4 impedance matching pad is designed to provide reliable impedance conversion between BNC 50 Ω plug (male) and F 75 Ω jack (female) interfaces. Operating from DC to 2 GHz, this model delivers stable RF performance with a VSWR of ≤ 1.25 and an insertion loss of 5.7 dB ± 0.5 dB. The average input power rating is 2 W at +25 °C, with peak power handling capability up to 250 W for short-duration RF loads.The MP-B15F27A-2G/H44-H4 employs a bayonet-lock coupling mechanism on the BNC side and a screw-lock coupling mechanism on the F side to ensure secure mating. Center contacts are manufactured from phosphor bronze with gold plating over nickel underplating to maintain low contact resistance. Connector bodies are constructed from brass copper–tin–zinc alloy, while PTFE is used as the insulator material. A silicone rubber gasket and a brass alloy coupling nut provide mechanical stability and long-term durability.
ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. ROSNOL impedance matching pads combine dependable quality, consistent RF performance, and competitive pricing, making them effective alternatives to products from leading European and American RF manufacturers. Comprehensive customization services for materials, plating, and mechanical configurations are available upon request.
