Working in a cryogenic environment is one of the most challenging requirements for electronic equipment. SHF’s more than 20 years expertise in developing and manufacturing broadband amplifiers enabled the successful development of a small range of products for this application. A broadband amplifier is available as well as a bias tee. Coaxial connectors, hermetical sealed bulkhead adaptors and semi-rigid cables for cryogenic environment from our Japanese partner KMCO complete the portfolio.

The SHF 105C broadband amplifier is capable to operate in a cryogenic environment. A wideband operation up to more than 30 GHz is approved down to 23K. Apart from this amplifier the operation in cryogenic environment has also been verified for our SHF BT-45 bias tee.

To feed RF signals into a cryogenic chamber, the hermetical sealed bulkhead adaptors KPC292FFHA and KPC 185FFHA from our Japanese partner KMCO are a perfect solution. Internal connections inside cryogenic chambers can be made with special semi-rigid cable assemblies which are approved for a temperature range down to 300 mK. The materials such as Stainless Steel, Phosphor Bronze or pure Niobium are perfectly suited for use in cryogenic environment.
