Anritsu 3655E – Waveguide Calibration Kit; WR-12

The Anritsu 3655E is a WR-12 waveguide calibration kit engineered for precise VNA and VNMS calibration across the millimeter-wave spectrum. It delivers 12-term error-corrected measurements, enabling high-confidence characterization of devices and systems operating in the 60–90 GHz band. The kit includes flush shorts with 1/8 and 3/8 wavelength offsets, fixed terminations, and test port sections - all essential components for establishing traceable calibration references in demanding RF and microwave environments.
