Description
50Ω Hermetic Feedthroughs are ideal for applications where hermeticity is crucial to the transmission of RF signals. In these applications, TR Multicoax connectors are mated to the hermetic feedthrough on either end ensuring an impedance matched 50Ω channel between any two chambers.
Applications
- Dilution Refrigerators/Cryogenic Devices
- Quantum Computing
- Communications
- Scanning Electron Microscopy
Performance Attributes
| Feature | Benefit |
|---|---|
| Leak-proof Design | Max leak rate 4 x 10^-9 mbar*L/s |
| Extremely dense form factor | See individual flanges below for details |
| TR Multicoax assembly mates with just a few captive screws | Quick connection of multiple high-speed lanes |
| Robust Interface | Ensures no signal degradation up to 1000 mates/de-mates |
In-House Leak Testing Capability for Quality Assurance
- Helium Leak Detector
- Minimum detectable leak rate: 1·10-12 mbar·L/s
- Used for pass/fail testing
Functional Description
- Seamless TR Multicoax integration through feedthroughs in dilution refrigerators and vacuum chambers.
- Simplified hardware design and quick connect enabled by ganged multi-channel connector block.
- Torqued socket head cap screws ensure consistent, reliable, and repeatable electrical connection.
- Patented hermetic design ensures durability, reusability, and TR Multicoax compatibility.
Density Comparison
Configurations
Direct-to-Flange UD-HFT
- Direct-to-flange design provides extremely dense form factor and can fit 300+ channels in standard ISO 100 flange
oHFT
- Utilizes field replaceable O-ring design to independently add or remove feedthroughs within systems
- Extremely dense form factor replaces bulky surface mount hermetic coaxial connectors
