Patent ID: 7177662

Claim:
A multimode wireless communication device comprises: digital baseband processing module operably coupled to convert outbound data into outbound digital baseband signals and to convert inbound digital baseband signals into inbound data; analog to digital converter module operably coupled to convert inbound analog baseband signals into the inbound digital baseband signals; digital to analog converter module operably coupled to convert the outbound digital baseband signals into outbound analog baseband signals; first radio section operably coupled to convert the outbound analog baseband signals into first outbound radio frequency (RF) signals and to convert first inbound RF signals into the inbound analog baseband signals when the wireless communication device is in a first mode of operation; a second radio section operably coupled to convert the outbound analog baseband signals into second outbound RF signals and to convert second inbound RF signals into the inbound analog baseband signals when the wireless communication device is in a second mode of operation; and a diversity antenna arrangement, that includes a first antenna, a second antenna, a first diplexer coupled to the first antenna, and a second diplexer coupled to the second antenna, that selectively couples the first radio section to one of the first antenna and the second antenna, and that selectively couples the second radio section to one of the first antenna and the second antenna a first transmit/receive (T/R) switch operably coupled to the first and second diplexers and to the first radio section, wherein, when the wireless communication device is in the first mode of operation, the first T/R switch provides the first inbound RF signals from a first selected antenna of the first and second antennas to the first radio section and provides the first outbound RF signals from the first radio section to the first selected antenna; and a second T/R switch operably coupled to the first and second diplexers and to the second radio section, wherein, when the wireless communication device is in the second mode of operation, the second T/R switch provides the second inbound RF signals from a second selected antenna of the first and second antennas to the second radio section and provides the second outbound RF signals from the second radio section to the second selected antenna.
