Description
2.92mm to 2.92mm DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-K1K25A-40G50V/9XX-9X is a high-frequency DC Block connector featuring a 2.92mm plug (male) to 2.92mm jack (female) interface. Designed for precision RF applications, it operates from 70 MHz to 40 GHz with a nominal impedance of 50 Ω and supports a DC voltage rating of 50V. The connector ensures excellent signal integrity with a VSWR of ≤ 1.15 (≥ 23.13 dB) and insertion loss of ≤ 0.8 dB. Its inner DC block configuration enhances isolation performance, while the screw-lock coupling mechanism ensures secure and stable mating.This connector is constructed using premium materials: beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating; passivated stainless steel body and coupling nut; PEI insulators. It operates reliably across a temperature range of -40°C to +85°C and is fully 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.
