摘要:
Mobile apparatus with radio frequency architecture supporting simultaneous data and voice communications, in an embodiment, includes first and second antennas, a tranceiver unit, first and second radio frequency (RF) front-end units. The tranceiver unit has a plurality of first, second, and third RF terminals. The first RF front-end unit is coupled between the first antenna and first RF terminals to provide first paths for a high-speed data communication mode and a first mobile communication mode between the first RF terminals and first RF front-end unit. The second RF front-end unit is coupled between the second antenna and second and third RF terminals to provide second paths for at least one second communication mode between the second RF terminals and second RF front-end unit and to provide third paths for the high-speed data communication mode and first mobile communication mode between the third RF terminals and second RF front-end unit.
摘要:
A radio frequency circuit and a signal transmission method are provided. The radio frequency circuit comprises a primary antenna, a secondary antenna and a radio frequency integrated circuit. The primary antenna is electrically coupled to the radio frequency integrated circuit to transmit and receive at least one transmission/reception signal. The secondary antenna is electrically coupled to the radio frequency integrated circuit to receive at least one diversity reception signal. The radio frequency integrated circuit is configured to receive a specific diversity reception signal via the primary antenna and to transmit and receive a specific transmission/reception signal via the secondary antenna.
