In-Stock Cryogenic Isolators and Cryogenic Circulators
All of DiTom’s cryogenic RF isolator and circulators models below are designed to operate at cryogenic temperatures, primarily for quantum computing applications. Cryogenic devices are designed to operate below 77K and they will continue to operate into the mK range.
All DiTom cryogenic isolators and cryogenic circulators are measured at 77K prior to delivery and this data can be requested at any time.
Cryogenic isolators and cryogenic circulators are popular for use in certain markets including laboratories, quantum computing, radio astronomy, and space flight. Quantum computing RF isolators and quantum computing RF circulators are used by designers and manufacturers of quantum computers in the RF signal chain used to control the qubits within their quantum computers.
DiTom can customize quantum computing RF isolators and quantum computing RF circulators for customers who have specific requirements for size, performance, and magnetic interference. With our in house rapid prototyping capabilities, we can design a functional prototype of an cryogenic isolator or cryogenic circulator and provide measured data within a few days.
Contact DiTom and we’ll be happy to provide you with a cryogenic solution for your exact specifications.
Unshielded
Cryogenic Isolators and Cryogenic Circulators
- Thinner magnetic shunt, smaller overall package
- Ideal for applications where magnetic interference is low
- Part numbers ending in "Y"
Magnetically Shielded
Cryogenic Isolators and Cryogenic Circulators
- Thicker magnetic shunt to minimize magnetic interference
- Very low magnetic field levels at surface of unit, < 0.5G
- Part numbers ending in "YMG"
All DiTom cryogenic isolator part numbers in the table below start with “D3I” for single junction devices or “D4I” for dual junction devices.
All DiTom cryogenic circulator part numbers in the table below start with “D3C” for single junction devices or “D4C” for dual junction devices.
