Abstract
A wireless communication apparatus is capable of generating a gain/noise characteristics control signal for an amplifier and a filter without degrading an amount of electrical power, or distance information contained in the electrical power. The wireless communication apparatus includes: a rectifier circuit; a circuit power supply for receiving electrical power from the rectifier circuit so as to supply required electrical power; a sampling circuit for performing sampling on an output of the rectifier circuit; a discrete filter capable of performing discrete processing on an output of the sampling circuit so as to selectively remove a frequency component contained in the output of the sampling circuit; and power control for controlling a bias required for a radio transmitter and/or a radio receiver based on the DC component output from the discrete filter.
