Description
N 50 Ω Jack to N 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-N25N27A-2G/H4-H4 impedance matching pad is designed for impedance conversion between N 50 Ω jack (female) and N 75 Ω jack (female) interfaces. Operating from DC to 2 GHz, the device provides stable RF performance with a VSWR of ≤ 1.15 from DC to 0.5 GHz and ≤ 1.25 from 0.5 GHz to 1 GHz. Insertion loss is specified at ≤ 5.7 dB in both transmission directions. The average power handling capability is rated at 0.7 W at 40 °C, with linear derating to 0 W at 125 °C.The MP-N25N27A-2G/H4-H4 features screw-lock coupling and robust mechanical construction. Center contacts are manufactured from phosphor bronze with gold plating over nickel underplating. Connector bodies and coupling nuts are constructed from brass with copper–tin–zinc alloy plating, while PTFE insulators provide stable dielectric properties for long-term operation.
ROSNOL RF components are precision-manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations. ROSNOL impedance matching pads deliver consistent RF performance, dependable quality, and competitive pricing, making them suitable alternatives to products from leading European and American RF manufacturers. Comprehensive customization services are available upon request.
