Rf Simulation Software3/17/2021
However, when I open the Component Designer Coupler dialog, there is no Balun tab.I should make it clear that it performs basic RF simulation only, and is nothing like GenesysADS, Microwave Office, Ansoft Designer, HFSS, or of that ilk, so if you want a full-on EM solver, this is not your program.There are decent lists of other freeware RF simulation utilities here and here if youre interested.
I grabbed the files required for RFSim99 to run and created a standalone version which you can download below. Just extract this utility into a folder and run RFSim99.exe. You will need to manually create a windows file association if you want RFSim99 to automatically open the.cct files when double-clicked. You can get them to appear by hovering your mouse pointer over them, clicking and holding the left button, and dragging the pointer around and over the buttons. Generally, theyre set to -40dB, so I generally just highlight the field, delete everything in the field, then type in -40dB (or whatever I want my lower limit to be) and hit enter. ![]() Theyre a couple of my go-to utilities for quick transmission line simulationdimensions. Solution; save often and take care never to set the Smith Chart scale to 0. Solution; alter one of the impedance of one of the ports by a very small (insignificant) amount. Solution; place a high value resistor between the open end and ground. To then restrict small fonts to RFSim99, I created a secondary user with small font being selected. But the underlying mathematics that these programs use is not secret, it is in the public domain and there are low cost or shareware packages that will do the same computations. Often they lack the features and the extensive user interfaces, but the internal engines are running the same equations. For RF simulations the field is smaller, but one free program that repeatedly crops up in the listings is RFSim99. 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. S-parameters are easily measured with a network analyser, so RFSim99 avoids the problems of many packages by not being bound to third party models. ![]() The embedded link to his web site is no longer valid, but at pRF we were so impressed by the program that we tracked him down. We design point to multipoint broadband wireless access and backhaul systems. I was working as a contractor for some time and developing tools was a sort of ongoing hobby. Eventually, I decided to draw a line under it and make it available on the web.

In the help file is shown that there is such a coupler design capability.
