Provided is a front end circuit which can minimizes a size of a switch, thereby implementing a small and ultra-thin front-end circuit. According to a technical aspect of the present invention, the front end circuit comprises: a multi-switch including two ports in a first side, and multiple pairs of ports in a second side; and a filter unit forming a plurality of regression paths by using at least a part of the multiple pairs of ports in the second side of the multi-switch. The filter unit includes a plurality of filters positioned on the regression paths, respectively. |
