Current Stock:

For Microwave applications up to 40GHz, Allectra offers a Vacuum Feedthrough type 2.92mm (also called K-Type). This special high frequency version of an SMA connector uses no PTFE dielectric.

Frequencies up to 40 GHz with well defined VSWR and insertion loss give high performance for RF applications.

Every Feedthrough is delivered with a test certificate.

The seal to the Flange is made with a Viton O-ring (welded versions are in preparation). 

Smallest mounting flange is 1.33" CF or KF16. Up to four of these feedthroughs can be fitted to a 2.75" CF flange.
