Electronic Smith Chart
PowerSmith ©™ simulation tool
(VA3DIW)

Software without installation, without java, without java script, without Windows drivers, incompatible VBasic dll, outdated *.net libraries, #.net libraries, buggy C++ bs, suddenly expired forever licences, "Blue screen of Microsoft death", and endless administrative (/IT) tasks. Screw the ever changing java, incompatible versions of JS script, or mutually incompatible OS versions. Embedded is the way to go.
- A step to technology independence that succeeded -

With java, we can dream about long Fortran mantissa. Some compilers are not compliant with the C standard.
Do people deserve at least one working Win OS, based on gov. tax payer's subsidies? Going through PURGATORY from DOS1.12, DOS2.1, Win3.11, Win_NT4.0, Win95, Win98, Win2000, Vista, Win_XP, Win7 Home/Pro, Win8.1, Win10, Win11, 16bit, 32bit, 64bit, 128bit, Win25? he he. If you receive admin message "Access not granted", "File in use", it is not the right system. Ask what OS system runs fiscal financial account of your country!

There are many Smith Chart programs delivering HIGH PRECISION numbers, coming from very VOLATILE INPUT data. Software became religion.
Fake programs mimic PowerSmith: java works on every computer in different way. :-) The .net library don't show visible Radio_Buttons on Win11. :-) pity. Transmission Line rotates the wrong way. :-) Lossy Transmission Line 0.56 lambda rotates 0.75 lambda? :-) Chateau in the sky. Hot air. The best joke is obligatory back door in software.



               


Electronic Smith Chart PowerSmith©™ /simulator/s-parameters/noise figure/..

PowerSmith is RF simulation program. Use of the program is for analysis and matching of discrete circuits, lumped and distributed elements, transmission lines, stubs, baluns, antennas, amplifiers, receivers, transmitters, or FPGAs.

  • Complex impedance matching networks
  • Distributed component models
  • Lumped element models
  • Stubs
  • Lossy Transmission Line (0.667, 0.81)
  • Frequency sweep
  • Component tuner
  • SWR band chart
  • AutoMatch ™
  • Import data from VNA
  • Import reflection coefficients Γ,Rho
  • Import and Save your design files
  • S-parameters, analysis
  • LNA input and output gain circles
  • LNA stability analysis
  • LNA Noise circles and noise resistance
  • lab verified for 1.2GHz, 2.4GHz, 5GHz, 12GHz, and HF bands
  • Useful for design and analysis
  • SI units for math and properties

    Control question
    You have 1kW and the SWR=1.44; How much power do you burn?
    The load is ZL= 34.8 ohms or 72 ohms real.
    32.5 Watts is the heat. That's not the whole story.

    Any load impedance mismatch change the shape of output signal, harmonics, intermodulations, spectrum. You are not able to pull out full power. Where the power goes? The power bounces back from the load. Overloading power amplifier by voltage and extreme current in nodes. All Resulting in excessive heat and transistor thermal current run-away. Pssst! Keep low SWR. Decreasing temperature of active device by 10C degrees increases life span of the active device by about 102.5= 316x. (Arrhenius *1859-1927, activation energy).

    For the PowerSmith users
    We have tried to do something for small companies and radio-amateurs for development purposes and design. The treasure throve is in math. The NTFS file system is not supported. DOSBox.com can be downloaded in seconds. With DOSBox the program runs on Win10, Win11.


    How it works
    The program is result of long time hard work and debugging.
    Released version has security features against misuse and hacking to make a Win/MAC/Android/Linux clones. Some functions and functionality is blocked and modified. Extended s-parameter menu is functional for specific customers.
    I don't answer questions - "How to use Smith Chart?", "Where is the Help file with examples?".
