Patent ID: 7519390

Claim:
A multi-mode wireless communication device capable of concurrent wireless communications with a plurality of wireless communication systems, the device comprising: a multi-mode transceiver having a single transmit signal path and a single receive signal path; and a multi-mode baseband portion configured to configure an operating mode of the multi-mode transceiver in a time multiplex manner to each of the plurality of wireless communication systems to permit the concurrent wireless communications with the plurality of wireless communication systems, wherein the multi-mode transceiver comprises: a local oscillator (LO) having a programmable frequency that can be tuned to frequencies spanning at least transmit and receive operating bands corresponding to the plurality of wireless communication systems; a transmitter configured to receive a baseband transmit signal from the multi-mode baseband portion and frequency convert the baseband transmit signal, using the LO, to an RF transmit frequency in any one of the transmit operating bands of the plurality of wireless communication systems; and a receiver configured to receive RF signals from any one of the receive operating bands and frequency convert the RF signals, using the LO, to a baseband receive signal.
