SMA Feedthroughs - CF Flange, Double-Ended

These instrumentation feedthroughs have SMA coaxial connectors (50 Ohm matched impedance) on the air-side and vacuum-side. An air-side SMA cable plug is included with the feedthrough but a vacuum-side plug is not. With CF flanges, a suitable high temperature vacuum-side plug/cable combination, and the air-side cable disconnected, these feedthroughs are bakeable to 450°C and are UHV-compatible.
