Description
N 50 Ω Jack to F 75 Ω Plug Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-N25F17A-2G/H4-H44 impedance matching pad is designed to enable accurate impedance transition between N 50 Ω jack (female) and F 75 Ω plug (male) interfaces. Operating from DC to 2 GHz, the device 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.The MP-N25F17A-2G/H4-H44 features screw-lock coupling mechanisms on both N and F sides for secure and repeatable mating. Center contacts are manufactured from phosphor bronze with gold plating over nickel underplating. The connector bodies and coupling nuts are constructed from brass with copper–tin–zinc alloy plating, while PTFE is used as the insulator material to ensure stable dielectric performance.
ROSNOL RF components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. ROSNOL impedance matching pads deliver dependable RF performance, consistent quality, and competitive pricing, making them effective alternatives to products from leading European and American RF manufacturers. Comprehensive customization services for materials, plating, and mechanical design are available upon request.
