Waveguide & mm-wave Calibration Kits up to 325 GHz

Waveguide Calibration Kits from AT Microwave (WR19 to WR3): Precision Measurement Solutions for mmWave Testing

Accurate measurement is the backbone of any microwave and millimeter-wave system. Whether you are developing high-frequency components, validating performance, or conducting research, waveguide calibration kits are essential tools for ensuring reliable and repeatable results.

In this article, we take a closer look at Waveguide Calibration Kits from AT Microwave, covering their frequency range from WR19 to WR3, typical components, and key applications.

What Are Waveguide Calibration Kits?

Waveguide calibration kits are precision-engineered sets of standards used to calibrate Vector Network Analyzers (VNAs) for waveguide-based measurements. They eliminate systematic measurement errors and ensure that the results reflect the true performance of the device under test

Unlike coaxial calibration (SOLT), waveguide calibration typically relies on offset shorts, loads, and transmission standards, enabling accurate two-port calibration even at extremely high frequencies.

AT Microwave Waveguide Calibration Kits: WR19 to WR3 Coverage

AT Microwave offers a wide range of calibration kits covering waveguide sizes from WR19 down to WR3. This includes frequency bands from approximately 40 GHz up to 330 GHz.

Typical waveguide sizes include WR19, WR15, WR12, WR10, WR8, WR6, WR5, WR4, and WR3. This broad portfolio allows engineers to perform precise calibration across millimeter wave and sub terahertz frequency bands.
