【正文】 武漢理工大學(xué)《高頻電子線路》課程設(shè)計說明書摘要隨著現(xiàn)代通信技術(shù)的發(fā)展，各種通信設(shè)備層出不窮，涉及信息收發(fā)的各種儀器在調(diào)制和解調(diào)過程中，都必須依靠高精度的振蕩源，否則信息將無法發(fā)送和接收，因而個正通信設(shè)備中幾乎都離不開高穩(wěn)定度的振蕩源。振蕩器的種類有很多，包括反饋式振蕩器、負阻式振蕩器等，本次課程設(shè)計主要完成正弦波壓控振蕩器（VCO）的設(shè)計。包含有壓控元件作為頻率控制器件的振蕩器就稱為壓控振蕩器，壓控振蕩器廣泛應(yīng)用于各種發(fā)射機載波源、擴頻通訊載波源或作為混頻器本振源。本次設(shè)計利用晶體管、變?nèi)荻O管等分立元件完成相關(guān)設(shè)計，并達到設(shè)計要求。關(guān)鍵字：正弦波 振蕩器 變?nèi)荻O管 VCO1Abstract With the development of modern munications technology, a variety of munications equipment and related information sent to or from a variety of instruments in the modulation and demodulation process, must rely on highprecision oscillations, otherwise the information will not be able to send and receive, and thus a positive munication equipment almost without high stability of oscillations. Oscillator types include feedback oscillator, negative resistance oscillator, etc, this course is designed mainly to plete the sine wave voltage controlled oscillator (VCO) design. Contains a voltagecontrolled ponents as the oscillator frequency control device is called a voltage controlled oscillators, voltage controlled oscillators widely transmitters carrier source, spread spectrum munications carrier source or as a mixer local oscillator. This design using transistors, varactor diodes, etc to plete disc
