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.)
- 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. (This is a PDF file.)
