More Information
Summary:The invention discloses a radio-frequency switch comprising at least two signal transmission modules, a parallel branch circuit module, and a ground port. Each signal transmission module consists of a common port, a first serial branch circuit module, a second serial branch circuit module, and a branch port. The parallel branch circuit module is arranged between the ground port and a first terminal; and the first terminal is arranged between the first serial branch circuit module and the second serial branch circuit module. The common ports are also connected with common ports of other signal transmission modules in the radio-frequency switch; and the branch ports are connected with branch ports of other signal transmission modules in the radio-frequency switch. State switching of the radio-frequency switch is realized by changing states of the first serial branch circuit module, the second serial branch circuit module, and the parallel branch circuit module. In addition, the invention also discloses a contro
