Coaxial Calibration Kits
Coaxial Calibration Kits provide precision standards for accurate vector network analyzer calibration. Designed for RF laboratories, microwave component testing, mmWave measurements and antenna testing environments.
Precision Coaxial Calibration Kits for Accurate VNA Measurements
AO Microwave’s high-precision coaxial calibration kits are engineered to establish an accurate and repeatable electrical reference plane for Vector Network Analyzers (VNAs) up to 50 GHz. Fabricated with rugged, passivated stainless steel outer bodies and gold-plated beryllium copper contacts, our kits feature hand-polished calibration standards—including precision shorts, opens, loads, and thru adapters—ensuring minimal surface resistivity and preventing oxidation. Supporting standard calibration algorithms such as SOLT, SOLR, and TRM across standard connector interfaces (SMA, 3.5mm, 2.92mm, and 2.4mm), our kits deliver a return loss of typically > 40 dB for matching loads and precise phase alignment.
By correcting for systematic measurement errors, our calibration kits ensure high accuracy during device verification. They are essential for laboratory R&D, space-qualification component testing, and high-frequency production quality control.

Understanding Systematic Error Correction & VNA Calibration
An uncalibrated Vector Network Analyzer (VNA) suffers from systematic errors caused by cable reflections, adapter mismatches, and instrument drift. To establish an accurate, repeatable reference plane, these errors must be mathematically modeled and removed.
To resolve these measurement errors, AO Microwave provides high-precision coaxial calibration standards engineered to meet tight physical tolerances. By loading the calibration coefficient definitions (VNA state files) and measuring our known standards, the VNA computes error terms and removes them from subsequent measurements. This precision ensures high accuracy when evaluating active and passive coaxial components.
