Abstract
Large value embedded inductors are made by screen printing an inductor coil onto one or more ferrite tapes, and covering the ferrite tapes with one or more ferrite tape layer or layers. Low firing temperature green tapes surround the ferrite layer or layers. These green tapes can be expansion matched to gallium arsenide.
