The gold-plated brass body and gold-plated centre contact keep corrosion at bay in repeated mating cycles, rated for 500 mates. Inside, the PTFE dielectric holds the impedance steady across the band. This is the kind of connector you spec when you need a reliable RF feed-through that doesn't need a wrench to engage.
The 50 Ohm impedance matches standard RF cable and trace. The 4 GHz max frequency covers ISM, GPS, and cellular bands.
Installation and Termination
Termination is solder cup — you tin the centre conductor of your coax, insert it into the cup, and solder. The snap-on mating interface means the plug pushes onto a female SMB jack and locks with an audible click — no threads to cross.
