AD8345 140 MHz to 1000 MHz Quadrature Modulator

The AD8345 is a silicon RFIC quadrature modulator, designed for use from 140 MHz to 1000 MHz. Its excellent phase accuracy and amplitude balance enable the high performance direct modulation of an IF carrier. The AD8345 accurately splits the external LO signal into two quadrature components through .
