| Recently, X-parameters have been introduced and successfully used to model device non-linear behavior. The next important advance would be to utilize this formulation, constraint to load-independent X-parameters, to enable analytical non-linear microwave circuit design procedures. For this purpose, in this paper a blind iterative procedure is presented and validated in order to obtain the appropriate loadindependent X-parameters, focused around the chosen optimum impedance condition, necessary to enable accurate analytical non-linear circuit design to be undertaken. Furthermore, this blind iterative procedure has been experimentally implemented with the aid of a Nonlinear Vector Network Analyzer PNA-X coupled with a passive tuner. The ability of this procedure to speed up the generation of a suitable load-independent X-parameter model, with high accuracy in the desired impedance area for circuit design, has been demonstrated. Hence, traditional time consuming load-pull transistor characterization can be avoided. | |
