    hello I have two circuits that are attached.
    one is a oscillator circuit with a output from a transformer and another one that is 10 watt cw amplifier that has a input transformer that is 3 turns. I'm trying to match the output transformer of the oscillator to the input of the amplifier. Can someone guide me on how to do that

    The input impedance of the amplifier is 50 ohms.
    Therefore, to simplify the calculation, you can load the generator 50 Ohm resistor. Next, the calculation can be carried out to find the maximum voltage across this resistor using Spice program. Just need to know the parameters of the quartz resonator and the quality factor of the input winding.

    quartz operates at 13.56mhz and I'm not to sure what you mean by the quality factor of input winding if you mean turns then its 3 turns and with a reactance of 250ohmns and says the output link of that is 10 to 20% number turns on L1
