  1. Finally, the production, which is designed and debugged all by myself, c band fine resolution low phase noise frequency synthesizer was introduced by module, including respective schedule, frequency distribution and phase noise experiment results. then whole circuit phase noise result, picture of spectrum with spur were presented, by which above theory was proved, analysis of the result was given, and the existing problem as well as methods to resolve it were motioned

    論文最後對自己設計調試的樣機c波段小步進低相噪頻率合成器進行了分模塊介紹，包括各部分的原理框圖、頻率分配和相噪測試結果，然後給出了整個樣機的相噪、雜散頻譜測試結果，對上面提到的理論進行驗證，並對結果進行了討論分析，提出了樣機現存的一些問題和幾點解決措施。
  2. Then, detail discusses were given on. finally, on the basis of above analysis and research, by comparing various design methods, a l band agile frequency synthesizer with 256mhz bandwidth and 1mhz resolution was designed, whose switching time was within 4 us. however, the spur performance is to be improved

    最後，在對各種捷變頻技術綜合分析和研究的基礎上，經過反復的方案比較論證，設計了一個l波段256mhz帶寬，步進為1mhz的捷變頻頻率合成器，捷變時間在4 s以內，不過雜散指標還有待進一步改進。
  3. The tested results show that the designed c - band fmcw frequency source meets the waveform requirements, and its output power is more than 20dbm. however, the spur level was too high in the bandwidth

    實驗表明所設計的c波段fmcw頻率源達到波形參數要求，發射功率達到20dbm ，但帶內雜散抑制不理想。
