PROBLEM TO BE SOLVED: To provide a receiver comprising a reception RF front end having high linearity obtained by removing a disturbance wave whose frequency is close to that of a reception signal.SOLUTION: Disturbance wave extraction means is configured so as to comprise: first conversion means for performing first conversion processing on a signal output from a low noise amplifier by using an orthogonal local signal; band limitation means for performing band limitation on each of a plurality of signals output from the first conversion means; and second conversion means for performing second conversion processing on a plurality of signals output from the band limitation means by using the orthogonal local signal. |
