Would AC analysis of transistor circuits be usable at VHF ?

    Hi all,
    Will AC analysis do me when doing the math on low power VHF transmitters?
    It's impossible to get affordable software to simulate at RF frequencies.

    Cheers,

  2. When the entered parameters are correct ...

  3. You obviously haven't looked around enough.

    Actually I have looked around.
    Thank you very much.

    xanax,

    You could do a pencil and paper analysis and do fine at vhf. review how to
    compute and handle the collector to base capacitance and use "millers
    therom" to simplify the circuit so that a pencil and paper analysis is
    readily accomplished.
     
  6. Or use nice, free LTSpice from www.linear.com and just model paractics
    as additional components on the schematic...
