Introduction

The AD9986 is a highly integrated device with a 16-bit, 12 GSPS maximum sample rate RF DAC core, and a 12-bit, 6 GSPS rate RF ADC core. The AD9986 supports four transmitter channels and two receiver channels with four transmitter, two receiver (4T2R) configuration. The AD9986 is well suited for 2-antenna and 4-antenna transmitter applications requiring a wide bandwidth observation receiver path for the digital predistortion. The AD9986 supports up to a 6 GSPS complex transmit and receive data rate in single channel mode. The maximum radio channel bandwidth supported is 1.2 GHz and 2.4 GHz for the transmit and receive paths, respectively (4T2R). The AD9986 features a 16 lane, 24.75 Gbps JESD204C or 15.5 Gbps JESD204B serial data port, an on-chip clock multiplier, and digital signal processing capability targeted at multiband, direct-to-RF radio applications.
