The AD9146 TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital mod-ulation, and gain and offset compensation. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices, Inc. A 3-wire serial port interface provides for program-ming/readback of many internal parameters. Full-scale output current can be programmed over a range of 8.7 mA to 31.7 mA. The AD9146 comes in a 48-lead LFCSP. Product Highlights Ultralow noise and intermodulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies. A proprietary DAC output switching technique enhances dynamic performance. The current outputs are easily configured for various single-ended or differential circuit topologies. Compact LVDS digital interface offers reduced width data bus. Applications Wireless infrastructure W-CDMA, CDMA2000, TD-SCDMA, WiMAX, GSM, LTE Digital high or low IF synthesis Transmit diversity Wideband communications: LMDS/MMDS, point-to-point
The AD9146 is a dual, 16-bit, high dynamic range digital-to-analog converter (DAC) that provides a sample rate of 1230 MSPS, permitting multicarrier generation up to the Nyquist frequency.
