    Does anyone know how I can do a load pull test for the attached circuit. Not familiar with this test but I was told that load pulling means varying the complex load impedance until maximum output power is achieved. Couldnt find much by way of google. Nothing in my RF books (wes haywood, joe carr, david rutledge) as well.

    The circuit I am investigating comes from a TI cc2450.

    The goal is to figure out how well the BALUN performs by means of load pulling. If anyone can help I need test setup and measurement know how help.

    I need help with understanding the test setup and test measurements.
