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 is designed for 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.
