FMC+ / AD9082 MxFE Board
Signal Processing — AD9082 MxFE
FMC+ / AD9082 MxFE Board
The FMC+ AD9082 MxFE card converts digital IQ streams from the FPGA into analog/RF output. Thanks to Analog Devices MxFE architecture, a 4-channel high-speed DAC and 2-channel ADC operate together on a single integrated circuit.
It is intended for electronic warfare scenarios where up to 1 million pulses per second can be generated in analog form, with wide instantaneous bandwidth and high SFDR performance (~40 dBc). FM, PM, and S-RF modulation types are supported.
