Abstract
A passive device and a module for a transceiver are provided. The passive device for a transceiver includes a semiconductor substrate or a dielectric substrate, at least one capacitor, a dielectric layer, at least one inductor, a via hole, a metal electrode, radio frequency signal lines, and a radio frequency ground. The at least one capacitor is formed on the substrate. The dielectric layer is formed on the capacitor and the substrate. The at least one inductor is formed on the dielectric layer. The via hole penetrates through the dielectric layer. The metal electrode is formed in the via hole and electrically connects the capacitor and the inductor. The radio frequency signal lines are for the inductor and the capacitor. The radio frequency ground is formed on the substrate and isolated from the radio frequency signal lines. A reduction in the area required for mounting passive devices and modules thereof contributes to the downsizing of communication systems. Also, use of the MEMS technique can reduce insertion loss of inductors, which improves the communication quality of communication systems.
