OPTIMATCH MODULE
Introduction
The best way to learn how to use a program is by
using
it, so we've created several examples for you. Optimize all types of
impedance match networks for minimum VSWR, including a narrow band
L-Match and a complex broadband interstage match. We've also included
an example of device modelling.
We must assume a basic knowledge of the Smith Chart and impedance
matching techniques. If you are new to this topic, follow along, you'll
likely get the drift of it! If, after working thru the first example,
you are baffled, we suggest you obtain copies of the references listed
in
Appendix D for
study.
Another
good way to quickly "get
up to speed" on Smith Charts and impedance matching is to use our
SmithMatch
program. It gives you a detailed Smith Chart on your high resolution
graphics screen, a library of elements to work with, and introduces
you, by
example, to the fundamentals of impedance
matching using a Smith Chart.
All the impedance files, (we call them .IMP files), needed for the
examples to follow were transferred to the \mwsoft\optimatc\mwdata4 data
directory when you installed
OptiMatch.
System Z0
The system Z0 is the reference
impedance
used for VSWR calculations. Usually, but not always, it is 50 ohms; it
can be set to whatever real value you desire. In an interstage match
situation, you would want to set
the reference impedance equal to the real
part of the complex source impedance.
