Screen shot of series and parallel components added to schematic. See video below.

QuickSmith, 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.

Per the QuickSmith website --

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 drop method.

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

Windfreak Technologies Switchable Filterss - RF Cafe Website

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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
