Description
SMA 50 Ω Plug to F 75 Ω Jack Waterproof Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-A15F27A-2G-IPX7/H44-H4 impedance matching pad is engineered for reliable impedance conversion between SMA 50 Ω plug (male) and F 75 Ω jack (female) interfaces in applications requiring enhanced ingress protection. Supporting operation from DC to 2 GHz, the unit maintains a VSWR of ≤ 1.25 with an attenuation of 5.7 dB ± 0.5 dB. Average power handling is specified at 0.7 W at +40 °C, with linear derating to 0 W at +125 °C.The MP-A15F27A-2G-IPX7/H44-H4 employs screw-lock coupling mechanisms on both interfaces to ensure secure and consistent connection. Center contacts are made 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 insulators and a silicone rubber gasket provide sealing support for ingress protection. The IPX7-rated design supports use in demanding RF environments.
ROSNOL impedance matching pads are manufactured under ISO 9001-certified quality systems and comply with RoHS and REACH requirements. Designed for high performance, dependable quality, and cost-efficient pricing, ROSNOL products serve as practical alternatives to leading European and American RF brands. Comprehensive customization services are available to meet specific mechanical and performance requirements.
