Product Overview

AD8346 is a silicon RFIC I/Q modulator. Its excellent phase accuracy and amplitude balance allow high performance direct modulation to RF. The differential LO input is applied to a polyphase network phase splitter that provides accurate phase quadrature from 0.8GHz to 2.5GHz. Buffer amplifiers are inserted between two sections of the phase splitter to improve the signal-to-noise ratio. The I and Q outputs of the phase splitter drive the LO inputs of two Gilbert-cell mixers. Two differential V-to-I converters connected to the baseband inputs provide the baseband modulation signals for the mixers. The outputs of the two mixers are summed together at an amplifier which is designed to drive a 50 ohm load. It is used in application such as digital and spread spectrum communication systems, cellular/PCS/ISM transceivers, wireless LAN/wireless local loop, QPSK/GMSK/QAM modulators, single-sideband (SSB) modulators, frequency synthesizers, image reject mixer etc.
