<p><P>PROBLEM TO BE SOLVED: To provide an interference robust reception device, including an RF signal processor, frequency conversion interface and analog signal processor. <P>SOLUTION: The RF signal processor supplies an RF signal. The frequency conversion interface includes a passive mixer to generate an intermediate frequency signal by down-converting an in-band portion of the RF signal into a filter pass band and by down-converting an out-band portion of the RF signal into a filter stop band. With this, it is possible to filter the intermediate frequency signal in the pass band and the stop band of the filter. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
