摘要： 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.

摘要： Various aspects provide a radiohead circuit and a communication device including the radiohead circuit. In an example, the radiohead circuit includes an antenna interface, a radio frequency front end configured to receive a channel scan information including an information related to a target communication channel to be scanned from a communication device processor, perform an energy scan for detecting an activity of the target communication channel based on the channel scan information, generate an activity information including an information as to whether there is the activity on the target communication channel, and provide the activity information to a communication interface; the communication interface configured to couple the processor to a radiohead circuit-external processor external to the radiohead circuit.
