Substrate-Dependent Air-Wound Inductor Model in the DC-4 GHz Range

This paper describes the development of an equivalent circuit model for air coil inductors in the DC-4 GHz frequency range which includes substrate-dependent characteristics. The presented model is applicable to microstrip-mounted components. Limitations of the model are discussed as well as characteristics intrinsic to the inductors that greatly influence model extraction. A comparison of measured data and simulated responses is presented for the model.
