MCX coaxial connector engineering reference

Family-level coupling boundary only; exact electrical performance depends on configuration. Amphenol RF 919-NM174P51A1X is a right-angle MCX plug. Its table reports beryllium-copper body; gold/white-bronze finish, beryllium-copper contact; gold finish, pcb through-hole construction; solder contact termination, push-on coupling, 50-ohm impedance, a 6-GHz frequency ceiling and 500 minimum mating cycles. It identifies a PTFE insulator. These are exact-part manufacturer specifications, not family-wide ratings or independent test results.
