Cryogenic Infrared Filters
Withwave’s infrared filters are designed using a coaxial cable structure and magnetically loaded epoxy absorbers.
It reduces the noise photon flux and unwanted harmonic RF components for superconducting quantum systems.
Filters are rigorously tested and verified using Withwave’s 4 K cryogenic measurement system to ensure reliable performance at extremely low-temperatures.
