“Our new cryo attenuators have been tested to four milliKelvin,” said APITech’s Norm Hansen, Product Line Director. “Using our in-house resistor fabrication process, we are able to optimize the resistor material and substrate, as well as the mechanical design needed to deliver a thermally quiet attenuator solution that works at cryo temperatures.”

APITech’s cryo attenuators are available now. They will also be showcased at the upcoming IMS 2021 in Atlanta, Georgia.

Cryogenic refrigeration systems used in quantum computing installations require multiple stages of cooling and numerous RF cables to function, all of which introduces thermal noise. To prevent this thermal noise and ensure that a quantum computer’s quantum bits can be read, special cryo attenuators are needed. APITech’s experience delivering high reliability attenuators, terminations and related RF components for use in harsh environments and at extreme temperatures served as the foundation supporting its development of the new cryo attenuators.

Through its Inmet and Weinschel brands, APITech is a leading global provider of attenuators for communications, defense, space, radar and test & measurement.
