Abstract:
1. An electronic apparatus, comprising: an antenna; an antenna switch, having N transceiving ports, the antenna switch being coupled to the antenna and selecting one of the transceiving ports for transceiving signal with the antenna; at least one switch unit, having a first end, a second end, a third end and a fourth end, the first end of the switch unit being coupled to a first transceiving port of the transceiving ports, and the third end of the switch unit being coupled to a second transceiving port of the transceiving ports; a transceiver, having M transmitting ports and M receiving ports, one of the transmitting ports being coupled to the fourth end of the switch unit, and one of the receiving ports being coupled to the second end of the switch unit, wherein, the first end is connected to the fourth end of the switch unit and the third end is connected to the second end of the switch unit when the antenna switch is in a first status, and the first end is connected to the second end of the switch unit and the third end is connected to the fourth end of the switch unit when the antenna switch is in a second status, and M and N are positive integers; at least two modems, one of the at least two modems is configured to generate a selecting signal to switch the antenna switch into one of the first status and the second status; at least one first filter, coupled between the first end of the switch unit and the first transceiving port; and at least one second filter, coupled between the third end of the switch unit and the second transceiving port.
