Coaxial & Waveguide VNA Calibration Kits

General Information

When properly calibrated against known standards, Vector Network Analyzers (VNAs), provide the most accurate means of determining the one- and two-port network characterisitics of RF and microwave devices. Calibration effectiveness (a VNA's ability to reduce error terms to negligible values) critically and ultimately depends on the quality and integrity of the calibration standards used.

To help maximize calibration effectiveness, Maury produces a comprehensive line of coaxial and waveguide VNA calibration kits which consist of accurate, stable, and precise calibration standards for a broad range of VNA models. When properly used, these kits ensure a true evaluation of VNA performance.

Maury kits offer a range of performance and cost options which provide users with choices that are both techanically and economically suitable for a variety of intended application.


Most coaxial kits are designed for the short-open-load-thru (SOLT) calibration technique using sliding loads, although some low frequency and economy kits utilize fixed loads. Maury waveguide kits are primarily designed for the short-short-load-thru (SSLT) calibration method using 1/8 and 3/8 wavelength offset shorts and sliding loads. Some economy kits are available with fixed shorts and 1/4 wavelength shims. A series of thru-reflect-line (TRL) calibration kits are also available. Since each TRL cal kit contains a fixed load, they can also be used for an offset load calibration when this method is supported by the VNA.

Coaxial VNA Calibration Kits (cal kits)

Available for testing VNAs fitted with any of the modern, popular connectors including:

3.5mm (SMA)
Type N (50 ohm and 75 ohm)
TNC (including AFTNC)
BNC (50 ohm and 75 ohm)
14mm (formerly GR900)

Waveguide VNA Calibration Kits (cal kits)

Available in all common, standard rectangular sizes from WR650 (1.12 to 1.17 GHz) through WR22 (33 to 50 GHz), and in Millimeter Waveguide sizes from WR28 (26.5 to 40 GHz) through WR10 (75 to 110 GHz). These kits are available in the following configuration:

7005E Standard Waveguide Cal Kits
7006A Economy Waveguide Cal Kits
7007H TRL Waveguide Cal Kits
7005G Millimeter Waveguide Cal Kits
7005M Economy Millimeter Waveguide Cal Kits

Maury has also produced kits in less common rectangular size such as WR102 (7 to 11 GHz) and in half-height waveguide. See data sheets for more information.
