    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.

  3. In place of the antenna, of course!
     
  4. There are ways to simulate transmission lines, antenna performance, etc.
    What are you trying to do?
