KEYCOM's cryogenic millimeter-wave / microwave test fixtures and calibration kits are specifically optimized for testing the performance of patterns between edges of printed boards(edge type) , and circuit testing on the printed boards(probe type).
They are also designed to minimize heat capacity by miniaturizing their dimensions so they cool off efficiently, and materials with low coefficient of linear thermal expansion such as invar are used for major parts where high dimensional stability is required.
Operating frequency ranges from DC to 110GHz.
