creation of Nathan Iyer, has been around for a long time. It is without a doubt one of the
most feature-filled examples of RF design software around. Nathan recently released a Web-based
version of QuickSmith
on a GitHub server, which means it works on any platform with a browser - desktop or mobile
(some features are not accessible on mobile). Access is free, and you can save and reload
your design files rather than losing your work once you leave the website. Being online also
means that the latest version is always available. The screenshot to the right illustrates
where to place series and parallel components, and where to access the sweep parameter settings.
Be sure to scan through the FAQ page for tips like setting the component up/down button value
adjustments and turning features on and off.

QuickSmith is a Smith Chart based linear circuit simulation program. Some of the features
offered by this program are listed below: - Ladder network, elements are loaded using drag
Open and Save functions for schematic files
Impedance matching - Frequency/component sweep
Load impedance interpolation/extrapolation for frequency dependent loads
Q factors taken into account for network components
Amplifier design/analysis using gain/noise circles
Insertion loss and S21 graphs
Transmission line parameter calculations
Constant Conductance, VSWR and Q circles
Import and Export of data files
Help files with solved examples of network matching and amplifier design

The inventions and products featured on these pages were chosen either for their uniqueness in the RF engineering realm, or are simply awesome

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB.
Its primary purpose was to provide me with ready access to commonly needed formulas and reference
material while performing my work as an RF system and circuit design engineer. The Internet
was still largely an unknown entity at the time and not much was available in the form of
