Abstract

A reception device includes a low noise amplifier that amplifies a radio signal by a first gain, a variable gain amplifier that amplifies an output of the low noise amplifier by a second gain, an analog-to-digital converter that converts an output of the variable gain amplifier into a digital signal, a gain controller, and a saturation detection unit. The gain controller, when an amplitude of the radio signal exceeds a predetermined value, controls the first and second gains according to the amplitude of the radio signal, and completes the control within a predetermined period. The saturation detection unit detects saturation of the analog-to-digital converter based on the output of the low noise amplifier or the digital signal. The gain controller, after controlling the first and second gains a first time and the saturation is detected by the saturation detection unit, controls the first and second gains a second time.
