Abstract: A method and system are provided in which a device comprising a first or main phase locked loop (PLL) and a second or reference PLL, is operable to communicate utilizing a first and a second receiving antenna. The first PLL may generate a first signal based on a reference signal generated by the second PLL. A second signal may also be generated based on the reference signal. Data associated with a first radio access technology (RAT) may be received via the first receiving antenna utilizing the generated first signal. The first RAT or another RAT may be scanned via the second receiving antenna utilizing the generated second signal. The scan via the second receiving antenna may be performed concurrently with the reception of data via the first receiving antenna. A switch may be utilized to enable or disable scanning operations via the second receiving antenna.
