The RF design tool you didn't know you deserved it
Mystic is a RF design tool able to calculate a bunch of RF performance parameters including gain, noise figure, IP3 and IM3 products.
Mystic can be used to simulate both transmitters and receivers as well as link-budgets, signal conditioning circuits and LO generation ones.
Output is divided in 2 sections: results at stage level and at system level.
Chain stage results:
- Pin: Input power at the considered stage level
- Gain: Gain at the considered stage level
- NF: Noise Figure at the considered stage level
- IIP3: Input IP3 at the considered stage level
- Pout: Output Power at the considered stage level modelling the output power compression effect
- Linearity warning: in case one or more of the stages in your chain is working in a non-linear zone then a visual warning is displayed: in particular you get a "non linear" warning in case the output power reaches the 1dB compression point and you get a "saturated" warning in case the output power reaches the saturated one
System level results:
- Pin, gain, Pout and Noise Figure: please see above for description, results here are related to the complete chain
- IM3: The third order intermodulation products are referenced both to system input and output; IM3 is also expressed in dBc (input/input or output/output)
- IP3: The third order intercept point is referenced both to system input and output
.: how to
Working with data file in Mystic is just like working with a spreadsheet
but the design is guided and supervised by Mystic itself which means:
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, the following parameters are to be defined in order to characterize your component:
Component name: put here the name of the component/subsystem
Component type: double click to have access to a menu from which you can choose the component type among the following:
You can define any type of device by using one of the previous main types (for example a whole PCB could be defined as an “amplifier” or a “mixer”, 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 required frequency
Noise Figure: put here the NF value of the related component keeping attention to use the value at the required frequency
IIP3: put here the Input IP3 value of the related component keeping attention to use the value at the required frequency
P1dB: put here the Output P1dB value of the related component
Psat: put here the Psat value of the related component
In the installation path, and opened by default by Mystic, there is the example file “data.txt”.
It is a good example to start from and provides you with a generic transmitter design.
#Name Gain [dB] NF [dB] IIP3 [dBm] P1dB [dBm] PCB 5 17.52 10.06 18.5 Mixer -10 10 14.95 -4.05 Pre Amplifier 19.22 9.73 7 13.2 Filter -3 Driver Amplifier 15 9 19.74 23.3 Power Amplifier 12.5 9 29 26.87 Loss -2.5
Shortly, you have just to build your line up by using the characteristics of your components.
Please, have a look at the Mystic User Manual for further details.
- Where have I to take into account frequency?
Frequency is taken into account directly into the parameters you use to feed Mystic; so, for example, when you fill in the data file the gain of an amplifier 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 two 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 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 download link of 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?
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.
