Digital Frequency Discriminators



Wide Band Systems' Digital Frequency Discriminators meet precise system requirements for bandwidth, frequency accuracy, and resolution. Our DFDs employ 2:1 ratio correlater arrays to assure highest possible phase margin. This characteristic permits DFDs to operate at reduced RF Signal-to-Noise Ratios (SNR) in the presence of multiple simultaneous signals. Modular configuration permits frequency coverage from 0.5 GHz to 18 GHz.

Because of the customizable nature of Wide Band DFDs, we offer a variety of performance parameters including:

  • Out-of-band Flag
  • Frequency Modulation on Pulse (FMOP)
  • Phase Modulation on Pulse (PMOP)
  • Many other user-defined performance parameters and specifications

Typical applications include:

  • Radar Warning Receivers (RWR)
  • Electronic Intelligence Systems (ELINT)
  • Signal Intelligence Systems (SIGINT)
  • ESM (Electronic Signal Measurement)
