RF-Sampling S-Band Radar Transmitter Reference Design


Design files


Synthesis of waveforms appropriate for an S-band multifunction phased array radar (MPAR) is demonstrated with an RF sampling architecture utilizing the DAC38RF80, a 9GSPS 16-bit digital-to-analog converter (DAC). The RF sampling transmit architecture simplifies the signal chain, bringing the data converter closer to the antenna, allowing flexibility with high performance.

Evaluation board

DAC38RF80EVM — DAC38RF80 Evaluation Module

The DAC38RF80EVM is the circuit board for evaluating DAC38RF80/84/90 digital-to-analog converters (DACs). The EVM can be used to evaluate the performance of the DAC up to 9-GSPS sampling rate. It is designed to work with the FPGA-based pattern generator card TSW14J56EVM (Rev B and up). The (...)
