The gold-plated brass body and center contact resist corrosion through repeated connects in field-service gear. Polytetrafluoroethylene (PTFE) dielectric keeps signal loss low across the band.
RF Specs That Define the Signal Path
Rated at 50 Ohm impedance and usable from DC to 6 GHz, this plug matches standard 50 Ohm system impedance — no impedance bump at the interface if the board trace and cable are designed for 50 Ohm. The 6 GHz ceiling covers L-band, S-band, and most C-band down to the lower edge; beyond 6 GHz the interface geometry starts to limit return loss. Gold-on-brass center contact and body finish keep contact resistance stable through the 500-cycle rated life.
Mating and Termination in One Pass
Snap-on fastening — push the plug onto the mating MMCX jack until the retaining ring clicks; no threads to torque. The single-port design handles one coaxial line per connector. Mates with standard MMCX jacks of the same impedance — no cross-compatibility with SMB, which uses a different snap profile and larger shell diameter.
