ABSTRACT:
A direct conversion receiver includes a reference clock signal generating section for generating reference clock signal. An amplifier section amplifies a received signal and extracts a desired signal from the amplified signal. An extraction reference clock signal generating section frequency-divides the reference clock signal based on a frequency division data to generate first and second extraction reference clock signals. An extracting section extracts a data from the desired signal and the first and second extraction reference clock signals. A control and processing section outputs the frequency division data to the extraction reference clock signal generating section and processes the data based on a control section clock signal corresponding to the reference clock signal.
