Equipment and Components for the RF and Microwave industry

Miniature Synthesisers
ASY Series

  • Frequencies up to 32GHz
  • Frequency Steps 1KHz typical
  • 10MHz External or Internal Reference
  • Frequency Control Serial RS485 or Ethernet
  • Good Phase Noise
  • Compact Size
  • Non Volatile Memory

The ASY series are single phase-locked loop Frequency Synthesisers offering excellent performance combined with small size and a high degree of versatility for many applications in communications, radar and test instrumentation. These high performing units are ready to use with a minimum of set-up and provide high value solutions, often from stock.
