QuarterBack SMP/SMPM/SMPS Connectors

Amphenol / SV Microwave QuarterBack (QB) SMP/SMPM/SMPS Connectors provide a quarter-turn bayonet-locking feature on SMP/SMPM/SMPS interfaces. The connectors offer low insertion and extraction forces of 2lb/0.5lb (maximum) for SMP and 2.5lb/1.5lb (typical) for SMPM. The devices also exert less torque on board-mount connector solder joints during mating / unmating and permit more mating cycles without failure compared to full-detent SMP and SMPM. The QB connectors have a low VSWR through 40GHz (SMP) and 65GHz (SMPM and SMPS). Amphenol / SV Microwave QuarterBack (QB) SMP/SMPM/SMPS Connectors are ideal for high-vibration and test applications that require a large number of mating cycles.
