SMB Cable Assemblies
Compact snap-on RF cable assemblies designed for reliable performance in mid-frequency applications
Overview
Amphenol RF’s SMB cable assemblies provide secure, quick-connect RF solutions with excellent electrical performance—ideal for high-density applications that require ease of use and consistent connectivity.
SMB cable assemblies from Amphenol RF are engineered to deliver efficient signal transmission in a wide range of RF systems requiring compact size and quick mating. Featuring a snap-on coupling mechanism, these assemblies enable rapid installation and disconnection without compromising on mechanical stability. The 50 ohm SMB interface is designed to support applications operating up to 4 GHz, depending on the cable type, making it suitable for both commercial and industrial environments.
Available in a broad range of standard configurations, SMB cable assemblies utilize flexible coaxial cables like RG-174, RG-316, and RG-58, and are offered with straight or right-angle plug options. These assemblies are hi-pot and continuity tested to ensure reliable performance in the field. For applications in rugged or outdoor environments, IP67-sealed options are also available. The SMB interface provides a balance of size, performance, and user-friendly functionality, making it a dependable choice for system designers and engineers.
