Description
SMA 50 Ω Plug to BNC 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-A15B27A-2G/H44-H4 impedance matching pad is designed for impedance conversion between SMA 50 Ω plug (male) and BNC 75 Ω jack (female) interfaces. Operating from DC to 2 GHz, this model provides stable RF performance with a VSWR of ≤ 1.25. Typical insertion loss is specified at 5.7 dB ± 0.5 dB. The average input power rating is 2 W at +25 °C, with peak power handling capability up to 250 W, making it suitable for RF signal conditioning and measurement applications.The MP-A15B27A-2G/H44-H4 employs SMA screw-lock and BNC bayonet-lock coupling mechanisms to ensure secure and repeatable connections. Center contacts on both sides are manufactured from phosphor bronze with gold plating over nickel underplating. The connector bodies are constructed from brass copper–tin–zinc alloy, while PTFE is used as the insulator material for stable dielectric performance. A silicone rubber gasket enhances mechanical compliance, and the coupling nut is made from brass copper–tin–zinc alloy to provide reliable torque control.
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 performance, high quality, and competitive pricing, making them an effective alternative to products from leading European and American RF brands. Comprehensive customization services, including materials, plating, and mechanical design, are available to support specialized RF and microwave requirements.
