SMA panel receptacle, 50 Ohm, 18 GHz — what this connector is
The 1052533-1: The stainless steel body with gold finish provides corrosion resistance and consistent shielding over the connector's 500 mating-cycle life. PTFE dielectric keeps insertion loss low across the full band.
Obsolete — sourced through surplus and broker channels
No official replacement part number is on record. If your design can accommodate a parametric equivalent, review the SMA connector family from the same manufacturer for a current-production alternative with similar electrical ratings.
Mates with standard SMA plug — flange mount for panel feed-through
This is a standard SMA receptacle — mates with any male SMA plug (male pin, female outer thread). The threaded fastening gives a vibration-.
The 50 Ohm impedance sets the characteristic impedance for the RF path — match this to your transmission line and system impedance. The 18 GHz max frequency covers S through Ku bands; above that, the SMA interface starts to show mode conversion. 500 mating cycles is high for an SMA connector, suited for test equipment or field-swappable modules where the connector sees repeated connects and disconnects. Gold center contact plating on beryllium copper gives low and stable contact resistance over those cycles.
