Abstract:
VGAs amplify a baseband reception signal using a prescribed gain. HPFs stop part, in a band lower than a first cutoff frequency, of the amplified reception signal. An ADC AD-converts an output signal of the HPFs and thereby outputs a digital reception signal. An AGC controller outputs a gain code corresponding to a prescribed gain of the VGAs. A VGA gain corrector adjusts the gain of the VGAs by a prescribed amount.
