A broadband impedance matching integrated circuit apparatus comprising an alternating current ground plane, a direct current ground plane positioned proximate to the alternating current ground plane, a first conductive transmission line positioned a distance from the alternating current and direct current ground planes, a dielectric material layer with a thickness positioned on the first conductive transmission line, a second conductive transmission line positioned on the dielectric material layer wherein the first and second conductive transmission lines are electrically interconnected to behave as an electromagnetically coupled tapped autotransformer.

Broad band impedance matching device with coupled transmission lines

A stripline integrated circuit apparatus comprising a first ground plane, a stripline section positioned on the first ground plane, the stripline section including N stripline regions where N is a whole number greater than or equal to one, wherein each stripline region includes a stripline sandwiched therebetween a first dielectric layer with a thickness and a second dielectric layer with a thickness where each adjacent stripline is connected in parallel, wherein each adjacent stripline region is separated by a ground plane, a second ground plane positioned on the stripline region, and wherein the plurality of stripline sections are formed and electrically connected in series. The distances between the striplines and the ground planes are adjusted to vary the input and output impedance.
