Abstract
A wireless communication device includes: a wireless communication unit that handles a plurality of communication modes; a power supply circuit that transforms a power supply voltage and supply the power supply voltage to the wireless communication unit; a control unit that controls an output voltage of the power supply circuit in accordance with a communication mode; a current fluctuation suppression circuit that suppresses current fluctuation when the wireless communication unit executes burst communication; and a bypass circuit that disconnects a path to bypass the current fluctuation suppression circuit. The control unit controls the bypass circuit in accordance with a communication mode, and provides the bypass path when executing a communication mode without adopting burst communication.
Claims5
A wireless communication device, comprising:
- a wireless communication unit that handles a plurality of communication modes;
- a power supply circuit that transforms a power supply voltage and supplies the power supply voltage to the wireless communication unit;
- a control unit that controls an output voltage of the power supply circuit in accordance with a communication mode executed by the wireless communication unit;
- a current fluctuation suppression circuit that is arranged for suppressing current fluctuation at an output side of the power supply circuit when the wireless communication unit executes burst communication for intermittently and repeatedly executing transmission of a signal, with use of one or more of the communication modes;
- and
- a bypass circuit that disconnects a bypass path for bypassing the current fluctuation suppression circuit,
- wherein the control unit controls the bypass circuit in accordance with the communication mode executed by the wireless communication unit, and provides the bypass path when the wireless communication unit executes a communication mode without utilizing the burst communication.
