Description
SMA 50 Ω Jack to F 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-A25F27A-2G/H4-H4 impedance matching pad is designed to provide impedance transition between SMA 50 Ω jack (female) and F 75 Ω jack (female) interfaces. Operating over a frequency range 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 up to 250 W.The MP-A25F27A-2G/H4-H4 utilizes screw-lock coupling mechanisms on both SMA and F connector sides to ensure secure and repeatable installation. 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 insulators provide stable dielectric performance.
ROSNOL RF components are produced in ISO 9001-certified facilities and are fully compliant with RoHS and REACH regulations. ROSNOL impedance matching pads deliver consistent quality, reliable RF performance, and competitive pricing, making them suitable alternatives to products from established European and American RF manufacturers. Customization services for materials, plating, and mechanical configurations are available upon request.
