| Abstract: |
| An experimental study on a frequency synthesizer for airborne Synthetic Aperture radars(SARs) is described.Direct synthesizing and phase locked loop are combined and harmonics mixing and shock proof technology is adopted to implement the synthesizer.The synthesizer is featured by low power consumption,lightweight,small size and low phase noise. |
