PowerSmith (c)

PowerSmith by David Tomanek VA3DIW and Martin Kratoska OK1RR is program designed for impedance matching. Program may be used for broad range of applications, from discrete circuits to antennas. Generally, it is modeling tool.

The Smith chart employs series impedance values. e.g. values measured with an impedance bridge. PowerSmith handles conversion between parallel impedance of Zp and series impedance of Zs. Model of lumped elements and lossy transmission line is included. You may load data file with complex reflection coefficients. ELNEC, EZNEC, PowerSmith as well as microwave network analyzers generate these files. You may stop your design at any time and save your project using the proprietary data format. Features include s-parameters and scattering matrices. The program has a passive frequency sweeper and an active component tuner. Special cursor works as a magnifying glass, providing the means of exact impedance reading. The cursor is adjustable and there is no need for mouse. Of course, the PowerSmith has detailed SWR chart. The graphical interface reveals behavior of a complex load with a complex matching network. You may manually design your matching network, or use the features of AutoMatch. Choose frequency and impedance of your interest. The AutoMatch will search for matching combinations. The final draft is a schematic diagram of suggested matching networks. Added features are advanced LNA and amplifier analysis from the s-parameters, stability, gain circles and noise figure circles. The package is shareware. Please register at the authors.


System:
Try the Caldera OS, Open DOS, IBM DOS, DrDOS, PharLap, or Linux with emulation. Windoze is not designed for time-sensitive fast mathematical routines. Stable system is OPEN SYSTEM with free source code, where everybody can contribute.
We have tried to do something for small companies and hobbyist.

  Version for pda.   The Pi and T matching network was added.   Performance comparison: Reasonable agreement with RFSim99.  Microwave Office, MWO, has insufficient resolution to fake the computational speed.   MWO's method of moments doesn't work.  HP's ADS, Advanced Design System is a 3.5GB virus. Just the file allocation slows down the whole windoze machine. (windblows registers) Few portions are written by kids. It is another attempt to verify the concept, and disgust the user.   Eagleware reboots the machine. Change the OS system date and watch.. "Eagleware" has memory handling difficulties.   Fun.   Just hot air. Hot air. Most of the download websites are shut down.:)). Mirror at high seas.
