Cryogenic Filters
Cryogenic filters are low frequency (<1 GHz) low-pass filters that are used to filter out unwanted high frequency signals from signals that user is feeding to cryogenic device or signals that are returning from device to room temperature measuring equipment. The standard RC low pass filters contain surface-mount resistors and capacitors. We also make custom filters with inductors, feedthru capacitors and feedthru filters.
