摘要： According to one embodiment, an RF frontend IC device includes a first RF transceiver to transmit and receive RF signals within a first predetermined frequency band and a second RF transceiver to transmit and receive RF signals within a second predetermined frequency band. The RF frontend IC device further includes a full-band frequency synthesizer coupled to the first and second RF transceivers to perform frequency synthetization in a wide frequency spectrum, including the first and second frequency bands. The full-band frequency synthesizer generates a first LO signal and a second LO signal for the first RF transceiver and the second RF transceiver to enable the first RF transceiver and the second RF transceiver to transmit and receive RF signals within the first frequency band the second frequency band respectively. The first RF transceiver, the second RF transceiver, and the full-band frequency synthesizer are integrated within a single IC chip.
