The Windows ® program for designing Class E amplifiers

This program simplifies the design of the single-ended class E amplifier. Operation is intuitive and encourages circuit exploration.

We are now at revision 2.08.

• 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 up and down 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.
  
  
• 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.
