April 2019: Allectra now offers a double-sided SMA feedthrough for UHV with an extended frequency range up to 27GHz. This is in addition to the 18GHz SMA Feedthrough.
These “Super-SMA” versions are a cost effective alternative to the SMA-K or 2.92mm types, if frequencies above 27GHz are not required. Housing is Stainless Steel with gold plated centre contact. The smallest mounting flange is 16CF. Up to 4 of these feedthroughs can be fitted to a DN40CF flange.
