产品详情

This user guide serves as the main source of information for system engineers and software developers using the ADXBAND16EBZ. This platform contains four AD9084 software-defined, direct sampling mixed-signal front end (MxFE), including an RF front end, clocking, and power circuitry. Common target applications are phased array radars, electronic warfare, and ground-based SATCOM. The receive and transmit RF front ends have bypass configurations that allow customized frequency ranges of less than 8GHz up to 18GHz.

The ADXBAND16EBZ highlights a complete system solution. This platform is intended as a testbed for demonstrating multichip synchronization as well as the implementation of system-level calibrations and signal processing algorithms. The system is designed to mate with a Xilinx VCU118 evaluation board, which features the Virtex UltraScale+ XCVU9P field-programmable gate array (FPGA), with provided reference software, hardware design language (HDL) code, and MATLAB system-level interfacing.

A 16 transmit and 16 receive calibration board (ADXBAND16EBZCAL) can be used to develop system-level calibration algorithms to demonstrate power-up phase determinism. The calibration board demonstrates combined-channel dynamic range, spurious, and phase noise improvements that can also be controlled via a MATLAB add-on when connected to the peripheral module (PMOD) interface of the VCU118.

APPLICATIONS

  • Phased-array, radar, electronic warfare, and satellite communications (SATCOM)
  • Communications infrastructure (multiband and mmWave 5G)
  • Electronic test and measurement
