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. ## Technical Specifications • **Frequency Range:** 60 GHz to 90 GHz
• **Waveguide Standard:** WR-12
• **Calibration Type:** Opens, shorts, and broadband loads
• **Error Correction:** 12-term
• **Standard Components:** Two flush shorts (1/8 and 3/8 wavelength offsets), two fixed terminations, two test port sections
• **Optional Configuration (3655E-1):** Includes sliding terminations and pin depth gauge
