Title:
VARIABLE DEVICE CIRCUIT AND METHOD FOR MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2008277743
Kind Code:
A
Abstract:
To provide a variable device circuit having stable/low loss circuit characteristics that is manufactured at a low cost, by simultaneously forming a variable device and a stationary passive device, each having almost the same device structure on one side of a substrate, and to provide a method for manufacturing the same.
A high frequency variable component is provided with a variable switching device 21, a fixed capacitor device 22, a variable inductor device 23, a variable capacitor 24, and wiring that electrically connects each device formed on an upper surface of the substrate 1, and elecrical connections for each device can be selected by the actuations of the variable switching device 21.
