LNO640D1
LNO640D1
LNO 640 D1 is a low noise, low G vibration isolated Oven Controlled Voltage Controlled SAW Oscillator (OCVCSO) operating at 640 MHz. It can phase-lock to an external 10 MHz reference and is designed for airborne environments. The oscillator is housed in a 70mm x 70mm x 35mm package and offers three operating modes: Free running, Voltage controlled, and Phase Lock Loop.
- Excellent phase noise performance: -168 dBc/Hz at 10kHz offset, -174 dBc/Hz noise floor.
- BIT Status: Ready or Alarm.
- Airborne radars.
