gunn diode 解釋
甘恩二極體
  1. In addition, this paper numerically investigated the influence of the lumped parameters of the gunn diode on the frequency of the oscillation, and the tuning techniques of the oscillation frequency of the active antenna

    本文還利用fdtd法數值研究了gunn二極體的集總參數對振蕩頻率的影響以及有源天線振蕩頻率的調諧技術。
  2. Be sure your gunn diode doesn ' t oscillate at audio or hf as well

    確信你的耿氏二極體沒有同時在音頻或高頻振蕩。
  3. The lumped circuit model of gunn diode was incorporated into the fdtd arithmetic

    Gunn二極體的集總電路模型被編入了fdtd演算法。
  4. First of all, single port negative impedance oscillator is analyzed in the thesis. a design method of gunn diode vco is introduced and an vco chip using gunn diode is fabricated. the substrate of the vco chip is gaas with dimension of 4. 4mmx3. 9mm

    本文首先對單埠負阻振蕩器進行了分析，給出了gunn二極體負阻振蕩器的設計方法，設計出了一個變容管調諧平面微帶gunn二極體vco晶元，該晶元以gaas為襯底，尺寸為4 . 4mm 3 . 9mm 。
  5. It also gives the motive of the ka - band vco and mixer, associated with the subject ' s requirement and the realistic conditions, according to which a proposal is confirmed that the gunn diode and the varactor are mounted in the same cavity to fulfill the vco and an antiparallel diode pair is used to fulfill the harmonic mixer. in chapter 2, based on the basic theory of negative resistance oscillating, we analyses the gunn oscillator and it ’ s tuning character. chapter 3 introduces the theory of millimeter - wave harmonic mixer

    以此為根據結合課題需要和實驗室的實際條件，確定vco採用耿氏管腔體振蕩器形式，變容管與耿氏管安裝在同一個腔內以進一步減小體積，採用反向並聯二極體實現諧波混頻;第二章介紹負阻振蕩器理論及其調諧原理;第三章介紹毫米波諧波混頻器基本原理;第四章給出了振蕩器及諧波混頻器的設計過程，整個組件聯調的結果;最後是結束語，分析了電路中存在的問題，指出了改進方向。
  6. Compared with gunn diode, mesfet has the advantage of high efficiency, flexible design and easy to integrate. the two ports negative resistance oscillating network is analyzed and an extremum - line model of microwave transistor oscillating network output impedance is developed

    Mesfet較之gunn二極體在vco電路中有效率高、設計靈活性、便於集成等優點，所以本文著重介紹了變容管調諧微帶結構mesfetvco的研製工作。
  7. And the general procedures of these methods are summarized. finally, some practical problems are analyzed using fdtd, which include passive linear resistor element and nonlinear diode element in the microwave circuits and an integrated antenna embedded with an active gunn diode element and a dielectric cavity resonator

    最後，本文通過編程模擬了微波電路中的無源線性器件電阻和非線性器件二極體，含有有源器件gunn二極體的有源集成微帶天線以及介質腔諧振器等具體實例，來驗證各種方法的可行性和有效性，計算結果與實驗結果吻合。
