Product Details

The AD-JUPITER-EBZ is a versatile software-defined platform based on Analog Devices ADRV9002 and Xilinx Zynq UltraScale+ MPSoC. The ADRV9002 is a new generation RF transceiver that has dual-channel transmitters, dual-channel receivers covering a frequency range of 30 MHz to 6 GHz. This device has a high-quality RF linearity performance and a set of advanced features like fast profiles switching, flexible power vs. performance configuration, fast frequency hopping, multi-chip synchronization, and digital pre-distortion (DPD) for narrow and wide band waveform.

The evaluation platform includes XCZU3EG processing device that has a wide range of interfaces, making the system capable of local processing or streaming to a remote host. It comes integrated in a self-contained ruggedized aluminum case, which gives flexibility in evaluating and prototyping across different environments.
