Abstract
Presented research offers solutions for properties alternation of 3D LTCC inductors by variation of materials implemented for their fabrication. Investigated geometry is solenoid-shape micro-inductor. Two types of dielectric cores are applied to achieve increase of quality factor for over 40% at GHz range. Five different stacks of ferrite material combinations are implemented when either fine inductance adjustments are needed or in cases when higher quality factor is required at MHz range frequencies. Increase of starting inductance of solid dielectric core solenoid is realized in tuning range of (35–60) %. Different ferrite core configurations can double quality factor maximum.
