ABSTRACT:
In one embodiment, a method is provided for providing power to a radio-frequency (RF) component capable of operating under multiple communication standards, wherein each standard has a respective operating frequency. The method includes: receiving a communication standard signal indicative of which of the multiple communication standards the RF component is currently operating under; selecting a frequency for a power converter system in response to the communication standard signal, wherein the selected frequency is higher than a baseband frequency of the current communication standard for the RF component; generating an oscillation signal having the selected frequency; and operating the power converter system with the oscillation signal having the selected frequency to provide power to the RF component, wherein the operation of the power converter system causes minimal interference with the RF component operating under the current communication standard
