1. A method for assigning fixed parameters of a match network model by using a load impedance fixture, comprising: measuring an efficiency of an impedance matching network to generate a measured efficiency, wherein said measuring the efficiency is performed using the load impedance fixture that is connected to the impedance matching network; applying an input power at an input of the match network model to calculate a predicted output power at an output of the match network model when the match network model is assigned a fixed inductance, a fixed capacitance, and a fixed resistance; calculating a predicted efficiency of the match network model from the predicted output power and the input power, wherein calculating the predicted efficiency of the match network model from the predicted output power and the input power is performed by computing a ratio of the predicted output power and the input power; determining whether the predicted efficiency is within a predetermined limit from the measured efficiency; assigning the fixed inductance, the fixed capacitance, and the fixed resistance to the match network model after determining that the predicted efficiency is within the predetermined limit from the measured efficiency; and modifying the fixed inductance, or the fixed capacitance, or the fixed resistance, or a combination of two or more thereof upon determining that the predicted efficiency is not within the predetermined limit from the measured efficiency.
