Techniques for Validating a VNA Calibration with Microwave Probes

At the IMS2011 (International Microwave Symposium) show in Baltimore last year, our own Craig Kirkpatrick spoke about different techniques for validating a VNA calibration when using microwave probes.… [View More]

What are the VNA On-Wafer Calibration Coefficients for my ISS?

A simple answer is in the table below, however, a more advanced answer follows. This question may indicate a basic misunderstanding of on-wafer calibration. So, let's try to correct it. In coaxial… [View More]

New Research Paper – Scalable RFCMOS Model for 90 nm Technology

We just got our new research paper, Scalable RFCMOS Model for 90nm Technology, published by the International Journal of Microwave Science and Technology. This paper presents the formation of the para… [View More]

Hybrid, On-Wafer Calibration for 4-Port: The Best of LRRM and SOLR

System calibration is critical to getting accurate measurement data from RF wafer devices. During calibration, a set of known standards must be presented to the tip of the probe. This requires multipl… [View More]

Application of a Two-Tier Vector Network Analyzer RF Calibration

Two-tier RF calibration of a Vector Network Analyzer (VNA) using WinCal XE™ is a technique that allows two RF calibration error sets to be combined into one resulting error set for the VNA error… [View More]
