Technical Examples

A switch circuit for selectively switching connection of an antenna side circuit with a reception circuit and a transmission circuit of two communication systems one of which has a reception frequency band partially overlapped with a transmission frequency of the other. The switch circuit includes (a) a first switch unit for switching connection of the antenna side circuit with the transmission circuit side of the first and tie second communication systems and the reception circuit side of the first and the second communication system and (b) a second switch unit connected between the first switch unit and the reception circuit of the first and the second communication system for switching connection of the antenna side circuit with the reception circuit of the first and the second communication system. (c) The transmission circuit side of the first and the second communication system of the first switch unit is connected to a transmission circuit shared by the first and the second communication system. (d) When the transmission circuit of the first and the second communication system is connected to the antenna side circuit, the second switch unit cuts off the connection between the reception circuit of the first communication system and the first switch unit.
