Application Notes for Microwave Oscillators
FOR TEST EQUIPMENT, RWR, ESM AND OTHER APPLICATIONS
Kratos General Microwave offers a compact multi-band DTOs for various airborne and other applications, covering the 2-6 and 6-18 GHz frequency ranges. The units feature high speed, high accuracy and low phase noise. The modular design of the DTOs enables the user to select narrower frequency coverage if desired. Please consult the factory for individual requirements.
- Fast Settling Time
- 2 to 18 GHz in Various Sub-Bands
- Small Size
- For Airborne Applications
