Abstract:
A method of providing localized electrical fine tuning to a previously manufactured multiple element passive microwave or RF device on a substrate comprising the steps of:depositing a plurality of first contact pads and a plurality of first resistive and inductive lines onto first predetermined areas of said substrate, each of said plurality of first contact pads and each of said plurality of first resistive and inductive lines being in electrical contact, and each of said first resistive and inductive lines terminating in a respective capacitive plate located at a predetermined distance from a first end of corresponding ones of said multiple elements;depositing a plurality of second contact pads and a plurality of second resistive and inductive lines onto second predetermined areas of said substrate, each of said plurality of second resistive and inductive lines terminating in electrical contact with a second end of each of said multiple elements;depositing a plurality of respective nonlinear dielectric films onto predetermined areas of said first end of each of said multiple elements and each of said plurality of respective capacitive plates; andapplying a plurality of individual, adjustable bias voltages between each of said pluralities of first and second contact pads.
