Anritsu 36804B-15M Microstrip Calibration Kit, DC to 40 GHz

The Anritsu 36804B-15M is a microstrip calibration kit engineered for Vector Network Analyzer (VNA) calibration in microwave printed circuit board testing. It delivers the essential calibration standards - open, short, load, and transmission - required for accurate, repeatable on-substrate measurements of microstrip and coplanar waveguide devices from DC to 40 GHz.

Technical Specifications

• Frequency Range: DC to 40 GHz


• Substrate Thickness: Optimized for 15 mil (0.38 mm) substrates; compatible test fixtures accommodate 0.13 mm to 1.9 mm (5 mil to 75 mil)


• Line Offset Accommodation: Up to 12.7 mm (0.5 inches)


• Maximum Substrate Length: 50.08 mm (2 inches)


• Repeatability: 0.1 dB (via spring-loaded fixture jaws)


• Dispersion Compensation: Enables direct microstrip dispersion compensation for phase-shift linearization across frequency


• Calibration Coefficients: Provided on label inside top cover under foam padding

Key Features

• Spring-loaded jaw mechanism ensures consistent 0.1 dB repeatability across repeated measurements


• Flexible line offset range eliminates the need for custom fixtures in most applications


• Direct dispersion compensation capability addresses non-linear phase shift behavior in microstrip transmission media


• Individual calibration coefficients supplied for traceability and measurement confidence

Typical Applications

• On-substrate characterization of microstrip transmission lines and devices


• Coplanar waveguide (CPW) component measurement and validation


• PCB-integrated circuit and filter testing


• High-frequency device S-parameter acquisition

Compatibility & Integration This calibration kit works with use with the Anritsu 3680 Series Universal Test Fixtures, including models 3680-20, 3680K, and 3680V. The fixture architecture accommodates both microstrip and CPW measurement configurations through interchangeable jaw sets, enabling multi-technology on-board testing without dedicated hardware changes.
