Description
SMA to SMA DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-A1A25A-6G100V/9XX-9X is a precision-engineered DC Block connector designed for SMA plug (male) to SMA jack (female) configurations. Operating up to 6 GHz, it maintains a 50 Ω impedance and supports a DC voltage rating of 100V. With a VSWR of ≤ 1.2 (≥ 20.83 dB) and insertion loss ≤ 0.5 dB, it ensures excellent RF performance. The inner DC block structure enhances signal isolation, while the screw-lock mechanism provides secure and stable connections.Materials include beryllium copper center contacts with gold plating over nickel underplating, a passivated stainless steel body and coupling nut, PTFE insulators, and a silicone rubber gasket. The connector is RoHS compliant and functions reliably within a temperature range of -55°C to +90°C.
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.
