Abstract
Abstract An inductor structure, that houses a shorted transmission line inductor, includes components mounted within the volume carrying the shorted transmission line. Dielectric substrate layers which carry the shorted transmission line components and the electronic devices when sandwiched together can be coated with a metallic layer that acts as a shield protecting the internal components from external undesired sources. Mounting components within the inductor volume potentially saves space on a circuit board.
