Abstract
An RFVGA variably controls a gain according to an RFVGA gain control signal and amplifies and outputs a reception signal. A low-pass filter filters a signal output from a frequency converter. An OFDM demodulator generates a digital signal based on an output signal from the low-pass filter. A power detection evaluation circuit controls the RFVGA gain control signal based on a voltage value (DET) of the RFVGA gain control signal or a voltage value (DET) of the output signal from the RFVGA, and a voltage value (DET) of an output signal from the low-pass filter and a voltage value (DET) of an intermediate node of the low-pass filter.
