SMA to SMA DC Block | Screw-Lock | Gold-Plated Brass Body
Discover the high-performance DB-A1A25A-18G50V/911-91 DC block from ROSNOL, engineered to deliver exceptional RF/microwave interconnectivity. This robust SMA plug (male) to SMA jack (female) connector is designed for applications up to 18 GHz, offering a stable impedance of 50 Ω. With a superior Voltage Standing Wave Ratio (VSWR) of and a low insertion loss of dB, this DC block ensures minimal signal degradation, making it ideal for precision RF applications. It has a DC voltage rating of 50V.
Crafted with premium materials, the DB-A1A25A-18G50V/911-91 features a brass body and coupling nut, both with a gold plating over a nickel underplate, providing durability and a long service life. The center contact is made of beryllium copper with a gold plating over a nickel underplate, optimizing signal integrity and performance. The PTFE insulator and silicone rubber gasket further contribute to its reliable operation.
This DC block operates reliably across a wide temperature range of −55∘C to +100∘C and is fully RoHS compliant. The screw-lock coupling mechanism ensures a secure and stable connection. All dimensions are provided in both millimeters and inches, with precision tolerances for accurate fitting.
