Hello,

I was wondering, how is the an RF transmitter's output simulated ? I
mean, sure electrical simulations can be easily done with any
simulator out there, but how is the output power / range of
transmitter simulated ?
I am assuming that the RF transmitter will have generator to produce a
sinus wave of strong amplitude (probably a resonant network of some
sort) which will be fed to an antenna of quarter wavelength (don't
really know 1/4 lambda, but i been told its for maximum power
transfer). This being said, I still am at a loss at how the RF power
can be evaluated via electrival simulation.

Just use a resistive load and calculate the power in it.

There are ways to simulate transmission lines, antenna performance, etc.
What are you trying to do?

Check out "Equivalent Circuit of a Dipole Antenna Using Frequency
Independant Lumped Elements", 1993.
