| Abstract: |
| This paper describes the design of S band oscillator.The spectrum character of PLL is analysed.Through the testing,when Fourier frequency is 10 kHz and carrier is 2700 MHz,the phase noise of S BAND PLL source is lower than -93 dBc/Hz;Spurious is lower than -65 dBc and output power is higher than 10 mW. |
| Key words: S band PLL,Phase Noise,Source,VCO, |
