Panasonic AN6494NSA Datasheet
■ 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 provided with an LC filter, it can efficiently suppress IF-band local
harmonic spurious.
