RFSim99 Download


RFSim99 is a freeware software that can help you in RF simulation, in your projects, especially if you are trying to design radio filters.

RFSim99 works with S-parameters. This means that not only will it simulate and analyse circuits built out of its internal library of components, but that it can accommodate any circuit block or stage for which these are known.

Here is how to make RFSim99 work on Windows 7 64-bit OS. You must be running Windows 7 Professional OR Windows 7 Ultimate. Upgrade if you are running anything less.

The video below shows a Touchstone S-parameter s2p file that was generated on a homebrew N2PK VNA being simulated in RFSim 99. The s-parameter s2p file is for a ITT 10.7MHz roofing filter.
