MCX Jack for 75 Ohm RF Paths
The 919-422J-71P12G: It handles signals up to 12 GHz, making it a fit for video distribution, broadband telecom, and test equipment where 75 Ohm infrastructure is standard.
75 Ohm Impedance and 12 GHz Bandwidth
This connector is built for 75 Ohm systems — the standard impedance for composite video, CATV, and broadcast reference signals. The 12 GHz max frequency covers the full L-band through Ku-band, so it handles satellite IF, DOCSIS upstream, and HD-SDI without rolling off the signal. The snap-on coupling gives a quick, positive lock that holds through vibration, and the through-hole solder termination anchors the centre pin and shield to the board in one reflow pass.
As an MCX jack, it mates with any standard MCX plug (male) that has a snap-on collar — no threading, no bayonet.
