Title:
SWITCH DEVICE AND FRONT-END CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/239601
Kind Code:
A1
Abstract:
A switch device (10) comprises: a common terminal (Pan); a switch circuit (1) that switches electrical conduction between terminals (Ps10 and Ps101); a switch circuit (2) that switches electrical conduction between terminals (Ps20 and Ps201); and a switch circuit (3) that switches electrical conduction between at least one of terminals (Ps301 and P302) and a terminal (Ps30). Switch elements (E111, E121, E131, and E132) are included and are respectively arranged in a path connecting the terminals (Ps10 and Ps101), a path connecting the terminals (Ps20 and Ps201), and a plurality of paths connecting the terminal (Ps30) and the terminals (Ps301 and Ps302). The switch elements each comprise one or more stacked semiconductor elements, and the number of stacked semiconductor elements of a switch element (E121) is smaller than the number of stacked semiconductor elements of a switch element (E111).
