POWER APPARATUS, WIRELESS COMMUNICATION APPARATUS HAVING THE SAME, AND POWER SUPPLYING METHOD THEREOF

摘要

A wireless communication apparatus includes: a wireless communication unit which performs wireless communication; a converter which converts an input voltage into an output voltage in a switched-mode to supply the output voltage to the wireless communication unit; and a frequency adjusting unit which adjusts a frequency of a high frequency noise caused by a parasitic component of the converter, if the converter is switched, to prevent the frequency of the high frequency noise from interfering with a frequency of the wireless communication performed by the wireless communication unit.
