An X-band Sampling Phase-locked Synthesizer——PDRO |
|
() |
Abstract: |
The operation principle and technical features of a sampling phase -locked synthesizes are described in this paper. The low phase -noise and spurious features are especially analyzed, and the contribution of loop filter and loop capturing to stabilization of loop is emphasized. Finally the typical specification and performance of the X - band sampling phase - looked synthesizer is provided. |
Key words: microwave frequency synthesizer sampling phase - locked low phase - noise low spurious capturing loop circuit DRO design |
