... AN6494NSA Digital Communication Orthogonal Modulator IC Overview The AN6494NSA is an orthogonal modulator IC for digital cellular telephones. It incorporates a phase shifter and an APC circuit for indirect modulation in the 1.5GHz band. It efficiently prevents power from leaking to adjacent channels. When pro- vided with an LC filter, it can efficiently suppress IF-band local harmonic spurious ...
