.: how to
Working with data file in Mystic is similar to work with a spreadsheet
but the design is guided and supervised by Mystic itself:
no mess with row deletion or insertion as always happens when editing a spreadsheet file.
Components/stages are described row by row by the declaration of their electrical performance.
In particular, each row of the data input panel describes a stage of your line-up and
the following parameters are to be defined in order to characterize your component:
- Component name: put here the name of the component/subsystem
Please don't use the same name twice.
- Component type: double click to have access to a menu from which you can choose the component type among the following:
- Amplifier
- Attenuator
- Filter
- Loss
- Mixer
You can use any type of devices by using one of the previous main types
(for example a whole PCB could be defined as an “amplifier” or a “mixer” and the free space loss as a generic “loss”).
- Gain: put here the gain value of the related component keeping attention to use the value at the interested frequency
- Noise Figure: put here the NF value of the related component keeping attention to use the value at the interested frequency
- IIP3: put here the IIP3 value of the related component keeping attention to use the value at the interested frequency
- P1dB: put here the P1dB value of the related component
- Psat: put here the Psat value of the related component
Of course Mystic editor allows you to define your components or subsystems in a very driven way
asking you only those parameters required for the component type you're just inserting.
In the installation path, and opened by default by Mystic, there is the file “data.txt”.
It is a good example to start from and provides you with a generic but complete transmitter design.

Shortly, you have just to build your line up by using the characteristics of your components.

How can I know Microwave System Calculator's results are reliable?
Actually, as we are designers too, this has been the first question coming in our mind.
So we understand your point and want to answer what we did, and still doing, to make this tool as good as possible.
The easiest way is to look at an old project you did and compare the results of your old simulation and the measure made on the
prototype with the result got using Mystic.
For simple project, well documented, this shouldn't take more than 15 minutes.
We have to say that if the input you gave are reliable you'll be surprised how good will be the output ...
and how it was easy to get it!
Moreover it could be useful here explain the idea behind Microwave System Calculator.
It doesn't substitute your microwave/electronic design tool.
It is a system level tool; this means you can project your system using Microwave System Calculator but not design devices or
characterize electromagnetic structures.
If you start your design and make big efforts to get a reliable simulation than you find out that there is something limiting
your project, how do you proceed?
You start up it again from the beginning!
This can't happen if you use Microwave System Calculator because it gives
you the way to know if something at system level is wrong at a very early stage.
Where have I to take into account frequency?
Frequency is taken into account directly into the parameters you use to feed Mystic; so when you fill in the data file the gain
of an amplifier that you have to consider is the gain at the frequency you want to analyze.
Although this is not a big limitation cause this is a system simulator, it has been planned the implementation of the capability
to read directly s2p files, so you will need just to specify the frequency and the software will use the right value described
into the file.
What about the three different releases of Mystic?
Every Mystic release is addressed to meet the needs of different kind of users.
In particolar the following descriptions should clarify:
Mystic CL (Command Line) release: the last release without graphical interface.
It doesn't need the installation of the .NET framework.
Mystic Lite release: same as the PRO one, but with some limitation described
in the version comparison table.
Donations are suggested to support the development
of new Mystic versions.
Mystic PRO release: You get the link to download this version as soon as you donate:
please support the development of new Mystic versions.
How much should I donate to receive the link to download the PRO version of Mystic?
Well, it's up to you ...
Any donation is welcome and gives you access to the PRO version of Mystic.
You will receive the download link by e-mail immediately after donating.
Do you grant Mystic PRO licenses to universities and students without receiving any donation?
Yes, sure!
We only ask you to write us an e-mail explaining your needs and to which application
you would like to apply Mystic.
Please see the contact us page.
