Digital Baseband Generator
The Digital Baseband Generator is a conduction cooled board in a custom form factor which generates various types of signal
waveforms, such as multiple carriers and AM/FM modulated signals on-the-fly with minimal switching time (<20μs) using
Direct Digital Synthesis (DDS) technique.
The board receives input commands over Ethernet/optical interface and the FPGAs generate the desired waveforms up to 600
MHz. The output waveforms are interfaced to external world via SMA connectors. The board operates from external clock
source over SMA connectors.
The board is used in electronic warfare applications such as baseband signal generation and jammer applications.
