Multimode wireless communication device

摘要

A multimode wireless communication device includes a first radio section operably to convert outbound analog baseband signals into first outbound RF signals and to convert first inbound RF signals into inbound analog baseband signals when the wireless communication device is in a first mode of operation and a second radio section that performs similar functions in a second mode of operation. A diplexer section includes a first diplexer for coupling to a first antenna, and a second diplexer for coupling to a second antenna, and 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. First and second T/R switches are coupled to the first and second diplexers and to respectively, to the first and second radio sections.

1. A multimode wireless communication device comprises:
first radio section operably coupled to convert outbound analog baseband signals into first outbound radio frequency (RF) signals and to convert first inbound RF signals into 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; 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; and a second T/R switch operably coupled to the first and second diplexers and to the second radio section.
