Abstract:
1. A high-frequency switch module comprising: a multilayer board including insulating material layers and electrodes that are laminated on one another; a switch IC mounted on the multilayer board; a power supply wiring arranged to supply power to the switch IC; a first signal wiring through which a first high-frequency signal propagates; and first and second internal ground electrodes, a slit being provided between the first and second internal ground electrodes such that the first and second internal ground electrodes are spaced apart from each other by an interval defined by the slit when viewed in plan from above the switch IC; wherein an entire or substantially an entire first internal wiring located on the switch IC side of the first internal ground electrode is separated from the first signal wiring, and at least a portion of the first internal wiring includes the power supply wiring; and an entire or substantially an entire second internal wiring located on the switch IC side of the second internal ground electrode is separated from the power supply wiring, and at least a portion of the second internal wiring includes the first signal wiring.
