On the Design of Coplanar Bond Wires as Transmission Lines

Wire bonds are typically thought of as lumped electrical parasitic elements, and the usual design methodology is to make them as short as possible. Here another scenario is shown where the wire bonds may be thought of as transmission lines. Specifically, the practical system of "coplanar wires" is analyzed. If parameters are chosen carefully, especially with regard to wire height above substrate, they may impedance match the microstrip connector.
