  • Method and apparatus for downconverting a plurality of frequency modulated signals from a carrier frequency to baseband
    Patent number: 8301099
    Abstract: Circuits, systems, and methods are disclosed for controlling multiple antenna receive paths in a wireless communication device. In some embodiments, the circuit may include a pair of receiving antennas, a first receive path including a VCO coupled to receive a PLL signal and a first mixer coupled to receive a first signal from the VCO and a signal from one of the antennas, and a second receive path integrated separately from the first receive path including a second mixer coupled to receive a second signal from the VCO and a signal from the other antenna. By utilizing the output of the VCO to tune the first and second mixers in the first and second receive paths to the same phase and frequency, control of the multiple antenna receive paths may be optimized.
