Secure Locking SMPM RF Cable Assemblies

SV Microwave has released seven new secure locking QuarterBack® RF cable assemblies in the SMPM series. This product line utilizes a quarter turn bayonet style coupling nut with a locking feature for standard female and male bulkhead SMPM interfaces. All SV QuarterBack® products are ideal for high vibration and test applications that require a large number of mating cycles.

Features / Benefits:

Quarter turn bayonet locking feature on standard SMPM interface
Low VSWR through 65 GHz (SMPM)
Low insertion/extraction forces, compared to standard full detent SMPM, means less torque on board mount connector solder joints during mating and demating
Spring loaded positive mating feature allows excellent electrical performance even in extreme vibration environments
Low mating forces allow for more mating cycles without failure compared to full detent SMPM

Applications

Bench-top testing (PCB mount, cable connectors and adapters)
High vibration environments
Applications requiring a high number of mating cycles
