Description
BNC 50 Ω Jack to TNC 75 Ω Jack Impedance Matching Pad | DC to 2 GHz
The ROSNOL MP-B25T27-2GA/H4-H4 impedance matching pad is designed for impedance conversion between BNC 50 Ω jack (female) and TNC 75 Ω jack (female) interfaces. Supporting operation from DC to 2 GHz, the product maintains a VSWR of ≤ 1.2 and delivers stable RF performance across the operating frequency range. Average power handling capability is rated at 2 W at +25 °C, with peak power support up to 250 W.The MP-B25T27-2GA/H4-H4 employs a bayonet-lock coupling mechanism on the BNC side and a screw-lock coupling mechanism on the TNC side to ensure secure mechanical engagement. Center contacts are made from phosphor bronze with gold plating over non-magnetic nickel-phosphorus underplating. Connector bodies are constructed from brass copper–tin–zinc alloy, with PTFE used as the insulator material. A silicone rubber gasket enhances long-term mechanical reliability.
ROSNOL RF components are manufactured under ISO 9001-certified quality systems and are fully compliant with RoHS and REACH regulations. Combining dependable performance, high quality, and cost-effective pricing, ROSNOL impedance matching pads provide effective alternatives to products from established European and American RF manufacturers. Customization services are available to address specific mechanical, material, and performance requirements.
