SSMA Female Straight RF Connector Through Hole for PCB
The SSMA connector utilizes a 10-36 threaded coupling and is essentially a scaled-down version of the SMA;This interface is characterized by compactness, high frequency bandwidth, and highly reliable mechanical performance. The male contact was designed to be the same size as the cable conductor so that it could be used as the mating pin for optimized VSWR.
