Optimization of flat beam leads geometry of microwave HIC components
As a result of analytical study of mathematical models of in-circuit connections fragments it was established that electrical characteristics of flat beam leads can be described as a П-shaped equivalent circuit containing L to a passage and two capacities С to ground. The change of flat rectangular beam in-circuit connecting leads of HIC components for wedgeshaped ones allows to decrease spurious inductance and capacity by approximately 10% as compared to rectangular ones. For engineering evaluations of L and C parameters of the equivalent circuit analytic formulas were developed on the basis of beam lead physical dimensions.
