75 Ohm MCX Jack for 12 GHz RF Paths
The 919-415J-71P12G: The 75 Ohm impedance targets video distribution, broadcast, CATV headends, and high-speed data links where the standard 50 Ohm RF path would create a mismatch. The snap-on coupling gives a quick, positive mate for panel or board-edge connections that see periodic disconnect — test points, patch panels, or field-service access points. Rated to 12 GHz, this jack covers the full L-band through Ku-band for satellite IF distribution and DOCSIS upstream bands. The gold-plated brass body and beryllium copper center contact with gold plating deliver the 500-cycle mating life. That cycle count is typical for the MCX class, but the gold-on-gold interface means the contact resistance stays stable through those cycles — important for a 75 Ohm line where a degraded return loss from a worn contact would show up as a reflection in the passband.
