Frequency Multiplier Oscillators (FMOS)

The Frequency Multiplier Oscillator (FMO) is a compact 21 channel synthesized signal generator that provides transmit and LO signals for L-band and S-Band airborne radar systems. This design incorporates a unique isolation system for exceptional phase noise performance during vibration.

This ruggedized design has successfully passed environmental qualification for Temperature-Altitude, Humidity, Salt Fog, Vibration, Acoustical Noise, and Shock Testing. Interested parties should contact the factory directly for exact levels and conditions used for environmental test.
