Description
SMA 50 Ω Plug to F 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-A15F27A-2G/H44-H4 impedance matching pad is designed for impedance conversion between SMA 50 Ω plug (male) and F 75 Ω jack (female) interfaces. Operating from DC to 2 GHz, the device delivers stable RF performance with a VSWR of ≤ 1.25 and a nominal attenuation of 5.7 dB ± 0.5 dB. Average power handling is rated at 0.7 W at +40 °C, with linear derating to 0 W at +125 °C.The MP-A15F27A-2G/H44-H4 features screw-lock coupling mechanisms on both interfaces to ensure secure mating. Center contacts are manufactured from phosphor bronze with gold plating over nickel underplating. The connector bodies and coupling nut are constructed from brass copper–tin–zinc alloy, while PTFE is used as the insulator material. A silicone rubber gasket enhances mechanical compliance and assembly reliability.
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, stable RF performance, and competitive pricing, making them a cost-effective alternative to products from leading European and American brands. Complete customization services for materials, plating, and mechanical design are available.
