AD9988BBPZ-4D4AC

AD9988 is a highly integrated device with four 16bit, 12GSPS maximum sample rate, RF digital-to-analogue converter (DAC) cores, and four 12bit, 4GSPS rate, RF analogue-to-digital converter (ADC) cores. This device supports four transmitter channels and four receiver channels with a 4T4R configuration. This product is well suited for four-antenna TDD transmitter applications, where the receiver path can be shared between receiver and observation modes. The GPIO pins can be configured and toggled to support different user modes, while phase coherency is maintained. The maximum radio channel bandwidth supported is 1.2GHz in a 4T4R configuration and a sample resolution of 16bits. It is used in application like wireless communications infrastructure, W-CDMA, LTE, LTE-A, massive multiple input multiple output (MIMO), point to point microwave, E-band, and 5G mm wave, broadband communications systems, DOCSIS 3+ cable modem termination system (CMTS), communication test and measurement systems.
