Introduction Filter and Coupling Matrix Synthesis SW version 5.0.0 

Guided
Wave Technology's Coupling Matrix Synthesis software facilitates synthesis
of coupling matrices for Chebyshev filtering functions, with prescribed
finiteposition transmission zeroes. It also gives a fast and accurate overview of insertion loss, isolation, group delay and coupling coefficients versus filter order, return loss and transmission zero positions. The software allows placement of complex transmission zeroes, which opens up for group delay shaping. The software is intended for engineers, students and others who are engaged in design and analysis of microwave filters from both component and system point of views. To operate the software only basic knowledge about filters and filter terms are required. 
The 'engine' in
the software is similar to the tool which is available on Guided Wave Technology's
web site and which has been used by thousands of engineers and students
since 2002, which means that the software is based on
very well proven and tested principles. 
The main features
of the software are:

Even though lots of efforts have been put in making this software self explanatory and easy to use, some issues, terms and concepts may need some extra clarification, which is the intention of this small manual to give.
