Abstract

A wireless communication circuit in accordance with the present invention, is the wireless communication circuit having an amplifier for amplifying a signal, and includes an amplification route in which the signal passes through the amplifier; a bypass route for bypassing the amplifier; and a route-selector for selecting one of the amplification route and the bypass route. This arrangement prevents an amplification of a signal, being transmitted or being received, when a communication counterpart is in a close distance, thereby reducing an unnecessary power consumption.
