| 1. A coaxial feed-through radio frequency (RF) connector for installation in a bore of a conductive housing made of a first
material having a first coefficient of thermal expansion (CTE), comprising:
an RF signal ground-providing conductive shell comprising a conductive sleeve made of a second material having a second CTE
less than the first CTE, and a conductive ferrule joined thereto;
said conductive ferrule being made of a third material having a third CTE less than the second CTE;
said conductive ferrule surrounding and being spaced from an RF signal pin made of said third material by dielectric material
of a spacer hermetically joined thereto,
said dielectric spacer having a fourth CTE proximate the third CTE;
said conductive ferrule being conductively coupled to the housing to provide a secure ohmic RF signal ground connection between
the housing and said RF signal ground-providing shell;
said coaxial feed-through RF connector being hermetically sealable within the bore of the housing by a solder joint between
said conductive sleeve and the bore to retain the coaxial feed-through RF connector in the bore under compression.
