Double-mode transceiver

The invention relates to a double-mode transceiver which comprises a first transceiver device and a second transceiver device, wherein the first transceiver device comprises a first receiving link, a first transmitting link, a first RF filter, a first transmitting-and-receiving switching circuit and a first antenna. The second transceiver device comprises a second receiving link, a second transmitting link, a second RF filter, a second transmitting-and-receiving switching circuit and a second antenna. The first antenna, the first RF filter and the first transmitting-and-receiving switching circuit are connected in series. The first transmitting-and-receiving switching circuit is connected with the first receiving link and the first transmitting link. The second antenna, the second RF filter and the second transmitting-and-receiving switching circuit are connected in series. The second transmitting-and-receiving switching circuit is connected with the second receiving link and the second transmitting link. The first antenna is placed perpendicularly with the second antenna.
