技術說明

一種振盪器參數設計方法包括以下步驟：計算該選頻單元的複數品質因數，其中複數品質因數與選頻單元的相位響應特性以及穿透係數特性有關；以及選取複數品質因數的峰值區域所對應的操作頻率，作為振盪器的振盪頻率。其中，計算選頻單元的複數品質因數的步驟包括：量測選頻單元於不同操作頻率下的雙埠網路參數；以及利用公式計算複數品質因數，其中QSC為複數品質因數，ω0為選頻單元的操作頻率以及z11、z12為選頻單元的雙埠網路參數。本發明還提出了應用所述參數設計方法的微波振盪器及壓控振盪器。 A method for designing parameters of an oscillator is provided. The method includes following steps: calculating a complex quality factor of a frequency selecting unit, in which the complex quality factor is related to a phase response characteristic and a transmitted coefficient characteristic of the frequency selecting unit; and selecting an operational frequency corresponding to a peak region of the complex quality factor as an oscillating frequency of the oscillator. The present invention also provides a microwave oscillator and a voltage-controlled oscillator using the same. The step of calculating the complex quality factor of the frequency selecting unit includes following steps: measuring two-port network parameters of the frequency selecting unit at different operational frequencies; and calculating the complex quality factor by the formula.
