Paper Abstract

The paper presents the lumped model of RF amplifier for the generic SPICE circuit simulator. Model is constructed on the basis of measured s-parameter data set of the amplifier. Data – transformed to admittance (y) domain - is approximated by rational functions, which later are synthesized as RLC (sub)circuits. Final amplifier model - obtained by representing Y matrix of two-port circuit by the set of passive components and controlled voltage/current sources – is shown to be equivalent to the original s-based model and may be used in any generic circuit simulator.
