Radiation Tolerant Voltage Controlled SAW Oscillators (VCSOs)


Standard or Customizable VCSOs with Ruggedized Hybrid Construction

API Technologies’ VCSOs provide superior performance at operating frequencies of 350 MHz to 4,000 MHz. These Rad-Tolerant Voltage Controlled Oscillators deliver low phase noise performance (-109 dBc/Hz at 1 kHz) and low vibration sensitivity (2 x 10-9 per g).

API’s radiation tolerant VCSOs are standard products that can be modified to customer requirements for output frequency, frequency range and control voltage sensitivity.
