Overview

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.

Features

S-band transmitter reference design
Wideband frequency flexibility and planning
Demonstration using multichannel FM-modulated chirp waveforms
Tested reference design includes an evaluation module (EVM), configuration software, and User’s Guide
