This program simplifies the design of the single-ended
Class E amplifier. Operation is intuitive and encourages
"tuning" and 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.)
-
The supplied file is a self-extracting installation
routine. The program is installed in a standard manner.
You may place its icon on the desktop as a shortcut.
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.
Alan Melia, G3NYK, has written a paper using a
spreadsheet approach.
Greg Adams at CircuitSage has written a
MathCad routine.
