Abstract (en)
[origin: WO0211470A1] A communication system capable of communicating RF signals at any one of a plurality of communication standards through a common antenna is disclosed. The communication system includes a transmitting unit having at least one transmit RF information signal output, and a receiving unit having at least one receive RF information signal input and a GPS RF information signal input. The transmitting unit includes a modulator for modulating a transmit IF with a transmit baseband information signal to generate a transmit IF information signal and an upconverter for upconverting the transmit IF information signal with a transmit RF to generate at least one transmit RF information signal. The receiving unit includes a receive downconverter for downconverting the at least one receive RF information signal with a receive RF to generate a receive IF information signal, a GPS downconverter for downconverting the GPS RF information signal with the receive RF to generate a GPS IF information signal, and a demodulator for demodulating the receive IF to generate GPS and receive baseband signals. An antenna is coupled to the at least one transmit RF information signal output, the at least one receive RF information signal input, and the GPS RF information signal input for transmitting and receiving RF information signals.
