Abstract
A radio-frequency switch includes: at least two signal transmission modules, each signal transmission module includes a common port, a first series branch module, a second series branch module and a branch port; a parallel branch module; and a ground port. The parallel branch module is disposed between the ground port and a first terminal, and the first terminal is disposed between the first series branch module and the second series branch module. The common port is further connected with common ports of the other signal transmission modules in the radio-frequency switch, and the branch port is further connected with branch ports of the other signal transmission modules in the radio-frequency switch. State switching of the radio-frequency switch is realized by changing states of the first series branch module, the second series branch module and the parallel branch module.
