A CLASS OF BI-MODE RESONATORS CONSTRUCTED FROM A MULTILAYER STACK OF ORGANIC LAMINATES ENHANCING THE PERFORMANCE AND COMPACITY OF INTEGRATED PASSIVE COMPONENTS.

摘要

A class of dual-mode resonators built from a multilayer stack of organic laminates improving the performance and compactness of integrated passive components. The present invention relates to the design, topology and manufacturing of passive components integrated in multilayer organic laminates, which can be mounted on printed circuits, for processing the radio frequency signals and clearly distinguishable from the existing (between other, LTCC) by their strengths in performance, size, performance and reliability. By applying this invention, the baluns, filters, and multiplexers are produced, by standard methods, in a stratified stripline structure having 3 dielectric layers and 4 metal layers, in which the bi-directional resonators Modes are realized by 2 interdigitated transmission lines, printed on 2 metal layers arranged on either side of a central organic dielectric substrate allowing a strong transverse coupling. Thus, thanks to the very strong coupling between the transmission lines, the resonators make it possible to obtain two well-separated resonance modes and the resulting filter architectures can be controlled differentially or asymmetrically and without loss of space or performance degradation. These filters can be designed without via or localized element, with impedance adaptations made by captured lines and inter-resonator couplings that rely on the interactions of electromagnetic fields, which improves their compactness.
