中文拼音 [fùzǔèrjítǐ]
負阻二極體
英文
dynistor diode-
And the basis of microstrip is recalled. after this, we analyzed and computed several microstrip resonators with ads, making impedance match between the resonator and impatt diode
然後利用ads軟體對幾種微帶諧振器進行了分析和計算,使雪崩二極體的負載阻抗與其匹配。The results show that the electron mean drift velocity is affected by the cathode radius, the impedance of the load diode, the inner radius of vanes and the input voltage
結果表明電子平均漂移速度決定於陰極桿半徑、負載二極體阻抗、陽極慢波葉片內徑和輸入電壓。Bonded nr diode
鍵合負阻二極體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 。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。分享友人
