PROBLEM TO BE SOLVED: To provide a receiver comprising a reception RF front end having high linearity obtained by efficiently removing a disturbance wave considering dispersion of loop stability of a feedback loop circuit during manufacturing.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 an orthogonal local signal of a reception signal; band limitation means for performing band limitation on each of a plurality of signals output from the first conversion means; second conversion means for performing second conversion processing on each of a plurality of signal output from the band limitation means by the orthogonal local signal; and phase adjustment means for adjusting at least one of phases of the orthogonal local signals input to the first conversion means and the second conversion means respectively. |
