Study of a Fabry-Perot cavity in the microwave frequency range by the boundary element method," Absfruct-A method for deriving accurate L-band inductor models using 1-port 6xtured S-parameter measurements is presented, along with examples of successful filter designs using the models. Models were developed for a number of surface-mount and leaded devices with values ranging from 4.7 nH to 470 nH. The devices were measured in a coaxial test fixture on an HP8510B network analyzer, with fixture de-embeddmg performed using CAD software. The models are seen to fit measured data over a broadband, from low F W through resonance. To M e r validate the models, several filter circuits were developed and fabricated.The results of 5th-and 9th-order lowpass filter designs are presented here. The 9th-order Mter was optimized for the desired performance using the parasitic inductor models. Measurements confirm that the use of the models led to a successful design on the %rst pass." Finally, simulations show that this success would not have been achieved without the developed inductor models.
