AD8349 Datasheet (Analog Devices) - Quadrature Modulator

AD8349, Quadrature Modulator

The AD8349 is a silicon, monolithic, RF quadrature modulator that is designed for use from 700 MHz to 2700 MHz.

Its excellent phase accuracy and amplitude balance enable high performance direct RF modulation for communication systems.

The differential LO input signal is buffered, and then split into
