Cryogenic Millimeter-Wave / Microwave Test Fixtures and Calibration Kits

Model No. upj10

KEYCOM's cryogenic millimeter-wave / microwave test fixtures and calibration kits are specifically
optimized for testing the performance of patterns between the 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.
Their operating frequency ranges from DC to 110GHz.
