Multi-Band Frequency Locked Oscillator (FLO)

Kratos General Microwave has developed a new product line of Multi-Band Frequency Locked Oscillators (FLO). This product line is an enhancement to our free running Digitally Tuned Oscillator (DTO) products. This FLO combines the high speed of DTO with the high accuracy and long-term stability of a frequency locked source. The key specification feature of the FLO is a timing speed of less than 1μsec to settle within 1 MHz of the desired frequency.

SIMULATOR AND TEST SYSTEMS APPLICATIONS

The FLO was specifically designed for test systems and simulator applications. It is a low cost replacement for high cost direct synthesizers, in applications that the frequency setting time of 1 μsec is meeting the system requirements.    


  • Fast Settling (1MHz in 1μsec)
  • Wideband (2-18 GHz)
  • High Accuracy
  • Low Phase Noise
