AN ADJUSTABLE INDUCTOR BUILT IN AN ELECTRIC ELEMENT AND A CIRCUIT SUBSTRATE

摘要

PURPOSE: An adjustable inductor is provided to adjust values of an inductor on a circuit substrate, such as MCM, loading an electric element of an analog IC(Integrated Circuit) or an electric element of a super high frequency MMIC(Monolithic Microwave IC). CONSTITUTION: An inductor built in a circuit substrate, loading an electric element, connects a length adjusting wiring in several places having different length locations, in a main wiring of a standard-typed inductor circuit, connects the length adjusting wiring and the main wiring to a output terminal commonly in parallel, by using each connection wiring, and leaves one connection wiring, connected in parallel with an output terminal, and opens the rest of the connection wiring, electrically.
