Abstract
There is disclosed a low loss and high frequency lumped capacitor that is ideally constructed from LTCC dielectric material and deposited conductive layers. The capacitive plates are shaped as identical and overlapping serpentine conductive paths positioned on either side of a thin dielectric layer, with opposite ends of the conductive paths used for signal contact points. The net effect of the shape of the capacitive plates and the resulting approximately equal and opposite current flows is to cancel the majority of parasitic inductance at high frequencies, thus reducing insertion loss. Filters built using this construction of capacitor exhibit improved high frequency performance. This type of capacitor also has a simplicity of construction that allows integration into LTCC fabricated circuitry without requiring extra layers or terminals.
