Description
SMA 50 Ω Plug to F 75 Ω Plug Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-A15F17A-2G/H44-H44 impedance matching pad is designed to ensure accurate impedance transition between SMA 50 Ω plug (male) and F 75 Ω plug (male) connectors. Supporting operation from DC to 2 GHz, the device maintains 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 for short-duration loads.The MP-A15F17A-2G/H44-H44 features screw-lock coupling mechanisms on both connector sides to provide stable mechanical engagement. Center contacts are made from phosphor bronze with gold plating over nickel underplating. Both connector bodies and coupling nuts are constructed from brass copper–tin–zinc alloy, while PTFE insulators provide consistent dielectric characteristics. Silicone rubber gaskets enhance mechanical tolerance and long-term stability.
Manufactured under ISO 9001-certified quality systems, ROSNOL impedance matching pads are fully compliant with RoHS and REACH requirements. Offering dependable RF performance, consistent quality, and cost-effective pricing, ROSNOL products serve as a competitive alternative to major European and American brands. Flexible customization services are available to accommodate specific RF and microwave system needs.
