  • Reducing port requirement of antenna switch in multi-band electronic apparatus
    Patent number: 9172403
    Abstract: The invention provides electronic apparatus including an antenna, an antenna switch, at least one switch unit, and a transceiver. The antenna switch has N transceiving ports. The antenna switch selects one of the transceiving ports for transceiving signal with the antenna. The switch unit is coupled between the antenna switch and the transceiver. The transceiver has transmitting ports and receiving ports, and one of the transmitting ports is coupled to the switch unit, and one of the receiving ports is coupled to 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 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 in a second status.
