Description
2.4mm to 2.4mm DC Block | Screw-lock | Stainless Steel Body
The ROSNOL DB-Q1Q25A-50G50V/9XX-9X is a precision-engineered inner DC Block designed for ultra-high-frequency RF applications. Featuring a 2.4mm plug (male) to jack (female) interface, this component supports frequencies from 70 MHz to 50 GHz with a characteristic impedance of 50 Ω. It offers excellent electrical performance with VSWR ≤ 1.30 (≥ 17.69 dB return loss), insertion loss ≤ 0.6 dB, insulation resistance ≥ 5 GΩ, and a voltage rating of 50 V rms. The screw-lock coupling mechanism ensures secure mating and long-term reliability, with a minimum of 500 mating cycles.Built for durability and precision, the DB-Q1Q25A-50G50V/9XX-9X features a passivated stainless steel body and coupling nut, beryllium copper center contacts with 3 µinch gold plating over 80 µinch non-magnetic nickel-phosphorus underplating, and PEI insulators. A silicone rubber gasket enhances environmental sealing. The connector is lightweight at just 0.0038 kg and operates reliably across a wide temperature range from −60°C to +165°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.
