[Amps] voltage swing in BJT amp

["Drax Felton" <draxfelton@gmail.com>]

I've been playing with designing a 475kHz amp in LTSpice.

 

Does it matter how much the voltage swings on the output of a RF power
amplifier?

 

Given P = I * V, and phase matched into a 50+j0 antenna

 

Are 0.001ws at 0.1v @ 0.01a

really the same as

0.001w at 2v @ 0.001a

on the receiving end even though the voltage is 2000 times higher?

 

Any reason to prefer one design over the other at these low voltage levels?
