Title:
COUPLED TRANSMISSION LINE RESONATE RF FILTER
Document Type and Number:
Japanese Patent JP2023106483
Kind Code:
A
Abstract:
To provide a coupled transmission line resonate filter creating impedance matching between RF devices on the same substrate, and a method for manufacturing the same.SOLUTION: A method for manufacturing a resonate filter includes a step 102 of forming one or more interdigitated structures with electrical conduction channels on a photosensitive glass substrate, a step 104 of exposing at least one portion of the photosensitive glass substrate to an activating energy source, a step 106 of heating the photosensitive glass substrate for at least ten minutes above its glass transition temperature, a step 108 of cooling the photosensitive glass substrate to transform at least part of the exposed glass to a crystalline material to form a glass-crystalline substrate, a step 110 of etching the glass-crystalline substrate with an etchant solution to form a mechanical support device, and a step 112 of coating one or more electrical conductive interdigitated transmission lines, a ground plane and input and output channels with one or more metals. A resonate filter thus formed is covered with a lid that includes ground plates.SELECTED DRAWING: Figure 8
