Technical Overview
50 Ω coaxial feedthroughs preserve controlled impedance across the vacuum boundary, so RF signals and fast pulses pass without reflections. BNC, MHV, N, SHV, SMA and SMB styles cover DC to 1 GHz and voltages up to 20 kV.
Typical Applications
- RF and microwave vacuum systems
- Plasma diagnostics and probes
- Electron guns and ion sources
- High-frequency instrumentation
