Said to provide the superior phase accuracy and amplitude balance needed for direct RF modulation, AD8346 direct quadrature (I&Q) modulator enables reliable wireless connectivity for fewer dropped calls or connections. Applications are base stations, wireless local loop/smart antennas, satellites and radio links supporting PCS, GSM, CDMA and W-CDMA systems. The device is used in digital transmitters to streamline the IF stage and operates from 800 to 2500 MHz, which covers the major cellular and ISM bands. It interfaces with firm’s TxDAC family of D/A converters to provide a two-chip digital-to-RF transmitter solution. Supply voltage is 2.7V to 5.5V for temperatures ranging from -40°C to 85°C.
