Cafe Links |
Here's a huge list of
links to RF engineering payware, shareware and freeware, compiled by RF
Cafe. Includes software for circuit simulators, system simulators,
antennas, EM and transmission line simulators, schematic capture
software, and all sorts of useful RF-microwave links. This is the
mother lode.

| Ansoft Designer SV |
Here you can download
Ansoft Designer Student Version for free! This powerful software takes
microwave, RF, high-speed, and communications design to a new level.
This includes a complete RF linear circuit simulator, schematic and
layout view, powerful design utilities, and post-processing. It also
includes a complete set of linear distributed transmission line models,
discontinuities, vendor component parts, and ideal circuit elements.
The Student Version disables MOM analysis and models that are included
in the full for-fee version.

| Engineers
Calculator |
You just won't believe
how handy this tiny little calculator can be! Conversions, formulas,
and references for all sorts of electrical engineering problems (e.g.
formulas for microstrip, or frequency bands), mechanical engineering
(want to know how to convert horsepower to watts?), and general (all
kinds of math relations). It's just amazing. Download it and use it.
(You have to sign up for the RF GlobalNet online publication, which is
free.)

| HP AppCAD |
Here is a free(!)and
powerful microwave-RF CAD program from HP, which includes passive
circuits (including microstrip, stripline, ...), active circuits,
circuit design, and some very useful engineering tools (check out the
Complex Math Calculator for RF circuits.) You'll like this one. It runs
on Win2000, possibly XP.
|
| Transmission
line calculator TXline |
Here is a very useful
transmission line calculator for microstrip, stripline, coplanar
waveguide, grounded CPW, and slot line, from Applied Wave Research. You
can download this, and run the file under Windows.
|
| Transmission
line simulation |
Here's a program that
displays waves on transmission lines. Pretty basic stuff, but
interesting. Written by Greg Schussman at Univ. of California at Davis.
This works only on Windows machines.
|
| Two-port
network calculator |
Here's an
easy-to-use calculator that converts among S-parameters, Z-parameters,
Y-parameters, hybrid parameters, etc. Runs on Win machines.
|
| RF
Simulator |
This is a linear circuit
simulator with schematic capture, S parameter files, stability circles,
auto match, filter designer, attenuator designer and RF calculator.
From HyDesign Ltd. Runs under Win95/98/NT. Free download. |
