Patent ID: 7583934

Claim:
Transceiver apparatus for use in a multi-frequency communication system, comprising: a signal processor; an antenna-switch comprising a multi-switch, a transmission-multiplexer and a reception multiplexer, wherein said multiplexers are controllable by the signal processor; a frequency conversion circuitry having a transmission path and a reception path, wherein each of the paths communicatively connects the signal processor and the antenna-switch; and an antenna terminal having a first antenna and at least a second antenna that are connected to respective switches, the first antenna having at a first end a first transmission-connector for connecting the first antenna to the transmission path and having at a second end a first reception-connector for connecting the first antenna to the reception path, the at least second antenna having at a first end a second transmission-connector for connecting the at least second antenna to the transmission path and having at a second end a second reception-connector for connecting the at least second antenna to the reception path, wherein the antenna-switch, controllable by the signal processor, allows multi-frequency operation of the antenna terminal by combining a transmission-mode and a reception-mode of each of the antennas, the signal processor controlling the respective switches of the antennas such that, at a particular instant in time, each of the antennas is configured as either a transmit-only antenna or a receive-only antenna.
