SMA to SMA DC Block | Screw-Lock | Brass Body
Discover the high-performance DB-A1A25A-3G100V / H44-H4 DC block from ROSNOL, engineered to deliver exceptional RF/microwave interconnectivity. This robust SMA plug (male) to SMA jack (female) connector is designed for applications up to 3 GHz, offering a stable impedance of 50 Ω. With a Voltage Standing Wave Ratio (VSWR) of and a low insertion loss of dB, this DC block ensures minimal signal degradation, making it ideal for precision RF applications. It has a voltage rating of 100 Volts and operates across a wide temperature range of −60∘C to +165∘C.
Crafted with premium materials, the DB-A1A25A-3G100V/H44-H4 features a brass body and a brass coupling nut. The body is plated with a Copper-Tin-Zinc Alloy, while the coupling nut and center contact are gold plated with a nickel-phosphorus underplating, optimizing signal integrity and performance. The PEI insulator and silicone rubber gasket further contribute to its reliable operation.
This DC block is fully RoHS compliant. The screw-lock coupling mechanism ensures a secure and stable connection. All dimensions are provided in both millimeters and inches, with precision tolerances for accurate fitting.
ROSNOL’s precision-engineered RF connectors offer a competitive alternative to products from leading manufacturers in Europe, the USA, and other global markets. All Rosnol RF components are precision-manufactured in ISO 9001-certified facilities, and are fully RoHS and REACH compliant, ensuring environmental safety and global regulatory alignment. Customization services for plating, materials, and mechanical design are available upon request.
