Radio420S FMC

Nutaq’s Radio420S is an FMC card that gives waveform developers agile control over their RF interface by enabling them to:

  • Tune the frequency: Wide range from 300 MHz to 3.8 GHz
  • Avoid interference: 14 selectable RF bandpass filters
  • Isolate the band of interest: Selectable baseband bandwidth from 1.5 to 28 MHz
  • Achieve high quality SNR: Shielded, auto-calibrated radio
