MCX Receptacle, 50 Ohm — 6 GHz RF Interface
Gold-plated brass body and a gold-plated beryllium copper centre contact, with PTFE dielectric, keep the impedance stable through the interface.
Rated insertion loss of 0.1 dB at 6 GHz means the connector contributes minimal signal attenuation across the full bandwidth — the limiting factor in the RF chain will be the cable or the PCB launch, not this interface.
The voltage rating is the peak working voltage for the interface, not a continuous DC bus rating; in RF applications the signal voltage is well below this ceiling.
No official replacement part number is recorded in the lifecycle entry. No form-fit-function substitute is named in the official record; any cross-reference would require a pin-to-pin and interface check against the MCX standard.
