Description
SMA to SMA DC Block | Screw-lock | Brass Body
The ROSNOL DB-A1A25A-6G100V/911-91 is a robust DC Block connector featuring an SMA plug (male) to SMA jack (female) interface. It supports RF signals up to 6 GHz with a 50 Ω impedance and a DC voltage rating of 100V. The connector offers a VSWR of ≤ 1.2 (≥ 20.83 dB) and insertion loss ≤ 0.5 dB, ensuring reliable signal transmission. Its inner DC block design enhances isolation, and the screw-lock coupling mechanism ensures secure mating.Constructed with beryllium copper center contacts and gold plating over nickel underplating, the body and coupling nut are made of brass with gold plating. PTFE insulators and a silicone rubber gasket complete the assembly. Operating temperature ranges from -55°C to +90°C, and the product is RoHS compliant.
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.
