Description
SMA to SMA DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-A1A25A-6G50V/9XX-9X is a high-performance DC Block connector featuring an SMA plug (male) to SMA jack (female) interface. Designed for RF applications up to 6 GHz, it offers a characteristic impedance of 50 Ω and supports a voltage rating of 50V. The connector ensures stable signal transmission with a maximum VSWR of ≤ 1.2 (≥ 20.83 dB) and insertion loss ≤ 0.5 dB. It provides excellent insulation resistance and reliable DC blocking via its inner configuration. The screw-lock coupling mechanism guarantees secure mating and long-term durability.This connector is built with premium materials: center contacts are made of beryllium copper with 3 µinch gold plating over 100 µinch non-magnetic nickel-phosphorus underplating; the body and coupling nut are made of passivated stainless steel; insulators are PTFE; gasket is silicone rubber. It operates reliably across a wide temperature range from -65°C to +155°C and meets RoHS compliance standards.
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.
