What the 12 GHz and 75 Ohm Ratings Mean for Your Signal Path
The 031-70559-12G: The 12 GHz max frequency is the upper bandwidth limit — the connector will pass signals cleanly up to that point, with the impedance held at 75 Ohm throughout the mated pair. For typical video, broadcast, or data-acquisition links running below 3 GHz, this connector has headroom to spare. Pairing it with 50 Ohm cable or a 50 Ohm bulkhead creates a reflection at the junction that degrades return loss. The 500 mating cycles rating means the gold-plated center contact and nickel-plated brass body will survive repeated connect-disconnect cycles in test or field-service applications without significant wear on the mating surfaces.
Cable and Crimp Termination Details
The cable groups specified are Belden 4731R and 4731P, both 75 Ohm coaxial cables commonly used in CCTV, broadcast video, and serial digital interface runs. The kit includes the ferrule that compresses over the cable jacket to anchor the braid; it is not sold separately in this package.
