What’s a QuarterBack Connector?

SV Microwave’s QuarterBack connectors use a quarter-turn bayonet style nut with a locking feature for standard SMP interfaces.

There's lots of applications for cable assemblies in which you want some extra assurance of mechanical retention. SV Microwave's latest offering, which it calls a QuarterBack connector, goes beyond a simple blind-mate SMP (or SMPM) interface to a bayonet-style connection. Giving the connector a quarter-turn upon mating engages a spring-loaded mechanism that locks the cable assembly in place. Unmating requires just a quarter-turn in the opposite direction and pulling out the blind-mate pin.

SV Microwave also launched a combination offering. The company's mini-D RF connector, a D-submini style in an RF version, comes in an 8-port option that mates to a male PCB connector with a matching cutout to prevent mismating. Here again, additional mechanical retention comes in the form of thumbscrews.

At the back end of the connector are 0.047-in. pigtails that use SV Micro's Converge RF product to transition from the 0.047-in. diameter cable to a larger diameter. This sidesteps situations in which you might have physical restrictions near the PCB connector, or applications that call for longer cable runs where you can't afford the higher losses of the small-diameter cabling.
