摘要
無線電遙控技術(shù)在現(xiàn)代工農(nóng)業(yè)生產(chǎn)、科研、國防等領(lǐng)域有非常廣泛的應(yīng)用，隨著現(xiàn)代科技的發(fā)展，要求遙控技術(shù)越來越精細(xì)，需要設(shè)計者整體考慮，優(yōu)化設(shè)計整個遙控系統(tǒng)。本文從理論上和實(shí)驗(yàn)上對無線電遙控發(fā)射電路和接收電路進(jìn)行了系統(tǒng)的研究。論文主要包括兩大部分，發(fā)射電路的設(shè)計和接收電路的設(shè)計，又以 發(fā)射電路的設(shè)計為重點(diǎn)。首先，從整體著手，闡述了整體設(shè)計思路，然后對整體方案分塊設(shè)計。以求設(shè)計出最佳單元電路，然后整合在一起，使其整體電路更加精良。其次，我們開始了對各個單元電路的設(shè)計。從開關(guān)電路，到編碼電路，功率放大電路，調(diào)制電路，再到發(fā)射天線，我們都一一加以介紹。最后，我們選用PT2262作編碼器，F(xiàn)05C作發(fā)射模塊，設(shè)計出一套簡單、使用方便的遙控發(fā)射裝置。
關(guān)鍵詞：無線電遙控技術(shù)，發(fā)射電路，接收電路，主振電路，高頻功率放大器，調(diào)制電路，編碼器PT2262，發(fā)射模塊F05。
WIRELESS REMOTE CONTROL CIRCUIT
Abstract:
The field of radio frequency (RF)circuit design is currently enjoying a renaissance,driven in particular by the recent ,and largely unanticipaated,explosive growth in wireless telecommunications,Because this resurgence of interest in RF enigneers ,However ,in trying to synthesize the two traditions of “conventional”RF and lower-frequency IC desigers often find communication with each other difficult bacause of their diverse back-grounds and the differences in the media in which they realize their circuits .Radio-frequency IC design , particularly in CMOS, is a different activity altogether from discrete RF design.
Key words :wireless remote control an oscillating circuit a high-frequency power amplifier modualation code projectile
