    RF Load Pull advice Reply

    I am attempting to design a circuit employing a low power transmitter IC.  I'd like to couple it with an amplifier module, and in the process match it's output to an antenna.  For this, I'm considering using the technique of load pulling, something I don't have experience in.

    As I understand, this typically involves 2 impedance matching sets ("tuners"), and a power meter.  (I'm not attempting the technique utilizing a VNA). Can someone recommend some low cost equipment I'll need to make this technique work? I'll be workingat around 140 Mhz, and with power around 0.1 W.

     

    Thanks for any help

    It sounds as if this is more of a design (or even measurement) related question. You might be better off asking in one of the forums on http://www.designers-guide.org

    There are examples for SpectreRF which show how to use load pulling in simulation, but it doesn't sound as if that is what you are asking about.

    Kind Regards,

    Andrew.
