Multiport Vector Network Analyzer: From the beginning to modern signal integrity applications
With the recent digital systems and circuits outstanding increase in speed and complexity, multiport characterization at microwaves and millimeter waves is experiencing an impressive growth in demand and importance. Today the application of multiport techniques is shifting from typical microwave applications to signal integrity in computer technologies.
The importance of the VNA design as well as the calibration techniques which guarantees the accuracy is a must when low level crosstalk needs to be measured or when differential S-parameters are used.
The talk will present the most modern solutions for multiport measurements at microwave frequencies as well as their advance calibration techniques.
In particular the following topics will be given with the focus on multiport application:
Single-Ended and Differential S-Parameters Review
Error Models and Calibration Techniques
Accuracy of Multiport Measurements
Interconnection and Fixture Design for Multiport Measurement
