Abstract
A switch circuit includes an antenna port and at least one switch branch. Each branch includes a first, a second, and a third switches. The antenna port has one end connected with an antenna, and another end electrically connected with one end of the first switch of each branch respectively. The other end of the first switch of each branch is electrically connected with one end of the second switch corresponding to each branch and one end of the third switch corresponding to each branch respectively; the other end of each of the second switch corresponding to each branch is connected with a ground terminal; the other end of each of the third switch corresponding to each branch is electrically connected with one end of a load corresponding to each branch; and the other end of the load corresponding to each branch is connected with the ground terminal.
