Description
SMA Plug (Male) to SMA Jack (Female) DC Block | DC–12.4 GHz | Screw-Lock | Brass Body
The ROSNOL DB-A1A25A-12.4G100V/911-91 inner DC block ensures reliable signal isolation for high-frequency applications. It offers a 50 Ω impedance and operates from DC to 12.4 GHz with VSWR ≤ 1.25 (≥19.1 dB) and insertion loss ≤ 0.5 dB. Rated for 100 V DC, this component features a screw-lock coupling mechanism and weighs approximately 0.0045 kg, delivering secure connectivity and stable performance.Built for durability, the connector withstands temperatures from -55°C to +90°C and is fully RoHS compliant. Key materials include a beryllium copper center contact with gold plating over nickel, a brass body and coupling nut with gold plating, PTFE insulator, and silicone rubber gasket. These premium materials ensure excellent conductivity and corrosion resistance.
ROSNOL’s precision-engineered solutions offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All ROSNOL components are manufactured in ISO 9001-certified facilities and fully comply with RoHS and REACH regulations, ensuring environmental safety and global regulatory alignment. Customization services for materials, plating, and mechanical design are available to support specialized requirements across a wide range of RF and microwave applications.
