Q-Tech QT625S low phase noise Space Qualified, 100kRad(Si) Tolerant Hybrid SAW Oscillators (SO) provide superior performance at operating frequencies from 400MHz to 1.3GHz. QT625S delivers low phase noise, –110dBc/Hz @1 kHz offset, –170 dBc/Hz noise floor. Typical vibration sensitivity is less than 2ppb/g. The QT625S SO is a Class 2 hybrid per MIL-PRF- 55310, hermetically sealed, and operated from –40°C to +85°C. The design can employ internal frequency multiplication to optimize noise performance.
