Design of Low Phase Noise Frequency Synthesizer in Ka Frequency Band Miniaturization
The traditional design of frequency synthesizer is difficult to meet the integration requirements of miniaturization,low power consumption,ultra-wideband and low phase noise,so the design principle of frequency synthesizer is studied and the key circuit design method of frequency synthesizer is analyzed in detail.The experimental results show that the proposed frequency synthesizer not only successfully covers Ka band,but also exhibits a phase noise level better than-76 dBc·Hz-1 at 100 Hz offset,the dynamic power consumption during its operation is controlled within the range of 5 W,which meets the design requirements.
