Trent:

For Class E go here:

Be advised that EER must either use a very wideband
PWM system to minimize loss of sideband suppression
due to time delay mismatch in the two channels, or else
add a time delay to the RF channel.  Sounds easy but
it is a difficult path.

For an appnote with lots of graphics illustrating the PWM
system, go here:

Good luck!
