This program simplifies the design of the single-ended class E amplifier. Operation is intuitive and encourages circuit exploration.
Each of the six design parameters can be specified using a freeform entry scheme.

Each of those parameters can be “tuned” by clicking on the “+1%” and “-1%” buttons; see the graphic below. This allows instant feedback regarding what parameter affects what schematic trait.

Each parameter has a default value and entries are checked to reduce the probability of ridiculous results.

As an option the program will read a user-entered load value and match the amplifier to that value of load using an added L-network.

Data are written automatically to a “last session” file at program exit time, allowing a simplified program restart.

Your design can be written to a file with a path and name of your choosing for later recovery. This is in addition to the automatically-written last session file.

The program also writes a schematic (.ASC) file to drive the LTspice simulator from Linear Technology. (Tonne Software has no connection with Linear Technology.)

This program uses the revised equations presented in “QEX” for Jan/Feb 2001. They are close to but seem to be more accurate than the more-commonly used set of equations presented in “RF Design” for Summer, 1980.
