SEMICONDUCTOR INTEGRATED CIRCUIT AND HIGH FREQUENCY CIRCUIT MODULE

摘要

An inductor (4) and a capacitor (5) are formed on a semiconductor circuit board (2). One end of the inductor (4) is connected to a signal line (3), and the other end is connected to a ground pattern (6) formed to surround the region where the inductor (4) is formed. One end of the capacitor (5) is connected to the signal line (3) and the other end is connected to a ground pattern (7) formed to surround the region where the capacitor (5) is formed.Then, the ground patterns (6, 7) are separated and an LC resonator is configured. By using such LC resonator as an LC filter, a high frequency module is configured by integrating a plurality of semiconductor elements on one semiconductor chip.
