AD8345-EVAL datasheet



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 the polyphase phase splitter network. The I and Q LO components are mixed with the baseband I and Q differential input signals. Finally, the outputs of the two mixers are combined in the output stage to provide a single-ended 50 Ω drive at VOUT.
