SMA panel-mount jack for .085" semi-rigid cable
It presents a 50 Ohm impedance and is rated to 18 GHz maximum frequency, with a threaded fastening type and flange mounting feature for secure panel attachment. The stainless steel body carries a gold finish, and the centre contact is gold-plated beryllium copper.
The 18 GHz frequency ceiling and 50 Ohm impedance define this as a standard SMA interface for microwave signal paths up to K-band. The 500 mating cycles are typical for a gold-plated SMA — the gold-on-gold contact interface handles repeated connect-disconnect in test or field-service scenarios without significant degradation. The shield termination is solder, matching the semi-rigid cable jacket attachment method common in.085" assemblies.
The 1051046-1 is listed as Obsolete by the manufacturer. No official direct replacement or successor order code is recorded.
