Abstract
The present invention provides a wireless communication device that can receive a high frequency signal with a high sensitivity by reducing the noise received from a DC-DC converter, as well as a power measurement device equipped with such a wireless communication device. According to an embodiment, a wireless communication device includes: a switching-type DC-DC converter; a balun configured with a coil to output a differential signal based on a wirelessly received high frequency signal; a low noise amplifier driven by an output voltage of the DC-DC converter to process the differential signal output from the balun; and a ground voltage line that couples the low noise amplifier to a ground voltage source. The ground voltage line includes partial ground voltage lines that are arranged to face each other with the balun interposed therebetween.
