Product Details

The ADRF5730-EVALZ is a 4-layer evaluation board. Each copper layer is 0.7 mil (0.5 oz) and separated by dielectric materials.

All RF and dc traces are routed on the top copper layer whereas the inner and bottom layers are grounded planes that provide a solid ground for the RF transmission lines. Top dielectric material is 8 mil Rogers RO4003, offering optimal high frequency performance. The middle and bottom dielectric materials provide mechanical strength. The overall board thickness is 62 mil, which allows 2.4 mm RF launchers to be connected at the board edges.

Product Details

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
