AD9142ABCPZ

AD9142A is a dual, 16bit, high dynamic range digital-to-analogue converter (DAC) that provides a sample rate of 1600 MSPS, permitting a multicarrier generation up to the Nyquist frequency. The AD9142A TxDAC+® includes features optimized for direct conversion transmit applications, including complex digital modulation, input signal power detection, and gain, phase, and offset compensation. Application includes wireless communications: 3G/4G and MC-GSM base stations, wideband repeaters, software defined radios, wideband communications: point-to-point, LMDS/MMDS, transmit diversity/MIMO, instrumentation, automated test equipment.
