SMA Jack, 50 Ohm, 3 GHz — Right-Angle Through-Hole
Rated to 3 GHz, it handles common cellular, ISM, and instrumentation bands up to that ceiling. The gold-plated zinc alloy body and beryllium copper centre contact with gold plating give it corrosion resistance and repeatable electrical performance across 500 mating cycles.
No direct replacement is listed in the evidence. If you need a current-production SMA jack with similar specs (50 Ohm, right-angle, threaded), we can help identify alternatives; just note the 3 GHz ceiling and the right-angle through-hole footprint when cross-shopping.
50 Ohm impedance, 3 GHz max frequency, 500 V voltage rating. The PTFE dielectric keeps losses low through the band.
