Frequency synthesiser

Universal multifunctional low-noise synthesizer for S-band radars with a digital command interface

Functions:

  • to form repetition composite waveforms according to selected signal memory bank at the carrier frequency with high stability and low level of phase noises.
  • to form high stable heterodyne frequency, fully coherent with a repetition pulse carrier frequency and shifted along a frequency space on the intermediate frequency value (700MHz).
  • to form continuous high-stable reference clock signals for using them in digitizing system such as ADC.
