Some months back, Andy gave me this formula for calculating power
out of a single ended (class E) PA. It has been very helpful.

Pout max = Vdd ^2 / 2 / RL

Is there a similar formula to calculate power out of a class D
voltage mode PA (such as the W1VD design)?

I'm almost finished building my W1VD PA and I am wondering what
power output I can expect at different power supply voltages. I need
to make some sensible decisions about power supplies...

Thanks,
Paul N1BUG
