Hermetic Thread-in RF/Microwave Connectors

hermetic sma

Our 50-Ohm hermetic SMA and SSMA feedthru RF/Microwave connectors are designed for use in military and commercial applications where environmental conditions require an extremely rugged and reliable hermetic seal. PA&E manufactures these connectors from a variety of compatible shell and contact materials, in both laser weld and solder-in styles, which provide excellent electrical and environmental performance characteristics.
