Abstract:
1. A wireless transceiver, comprising: a first RF transceiving circuit for transceiving RF signals of one of a first frequency band and a second frequency band; a second RF transceiving circuit for transceiving RF signals of one of the first frequency band and the second frequency band; a first frequency synthesizer for generating a first carrier of the first frequency band; a second frequency synthesizer for generating a second carrier of the second frequency band; a switching circuit directly coupled to the an output of the first frequency synthesizer and directly coupled to an output of the second frequency synthesizer, the switching circuit being further configured to output the first carrier to the first RF transceiving circuit, and the switching circuit being further configured to output one of the first and second carriers to the second RF transceiving circuit according to a control signal; and an RF controller for generating the control signal.
