Abstract

The Cardiff behavioral model is a robust nonlinear tool for guiding nonlinear circuit design. This paper proposes a methodology to generate Cardiff AB models suitable for microwave frequency doubler optimization. Active Load-Pull data from both measurement and simulations are processed through a self-developed MATLAB application to extract and evaluate Cardiff AB models formulated with different mixing orders and number of parameters. Moreover, the role of harmonic source and load impedances in model extraction for frequency doubler design space prediction is studied.
