Patent ID: 8299843

Claim:
A communication device, comprising: a three-pole three-throw switch comprising six diodes connected in series with a same direction, wherein a common node of a cathode of a first one of the diodes and an anode of a second one of the diodes forms a first pole, and receives a first control signal via a first inductor; a common node of a cathode of the second one of the diodes and an anode of a third one of the diodes forms a first throw, and receives a second control signal via a second inductor; a common node of a cathode of the third one of the diodes and an anode of a fourth one of the diodes forms a second pole, and receives a third control signal via a third inductor; a common node of a cathode of the fourth one of the diodes and an anode of a fifth one of the diodes forms a second throw, and receives the first control signal via a fourth inductor; a common node of a cathode of the fifth one of the diodes and an anode of a sixth one of the diodes forms a third pole, and receives the second signal via a fifth inductor; a common node of a cathode of the sixth one of the diodes and an anode of the first one of the diodes forms a third throw, and receives the third control signal via a sixth inductor; a first capacitor to connect the first inductor to the ground, a second capacitor to connect the second inductor to the ground, a third capacitor to connect the third inductor to the ground; an antenna module comprising three antennas connected to the first throw, the second throw, and the third throw, respectively; and a transceiving module comprising three transceiving submodules and three control submodules, wherein the three transceiving submodules connect to the first pole, the second pole, and the third pole, respectively, a first one of the three control submodules connects to the first inductor and the fourth inductor, and generates and sends the first control signal, a second one of the three control submodules connect to the second inductor and the fifth inductor, and generates and sends the second control signal, and a third one of the three control submodules connects to the third inductor and the sixth inductor, and generates and sends the third control signals.
