【正文】 電路，調(diào)頻電路，混頻電路等一些基本的 電路，能夠幫助我們學(xué)習通信原理。 在此次課程設(shè)計中，我應(yīng)用高頻課上學(xué)的基本知識設(shè)計無線防盜報警器。在如今，居民財產(chǎn)安全得到越來越多的重視，防盜報警器能夠幫助居民保護自己的財產(chǎn)。我用 LC 三點式反饋振蕩器、射頻跟隨電路和高頻諧振功率放大器設(shè)計一了一中心頻率為 12MHz 的發(fā)射機，用高頻小信號放大器的相關(guān)知識設(shè)計一個能夠有聲光報警的接收機，將高頻課上所學(xué)的大部分知識都用到了，這對于我們學(xué)習高頻這門課有很大的幫助，也是很有意義的。 關(guān)鍵字： 報警 器 ， 射頻跟隨電路，高頻諧振功率放大器， LC 三點式反饋振蕩器，高頻小信號放 大器 Abstract Currently with puter work and munication is the characteristic of information technology is changing fast development, the munication electronic circuit in the book introduces in detail munication system circuit, the basic principle of analysis method and the typical application. According to the linear 3 circuits, nonlinear circuits and frequency conversion circuit to anize teaching material contents. Introduces the high frequency amplifier, small signal frequency power amplifiers, frequency multiplication device, high frequency oscillators, am circuit, FM circuit, frequency mixing circuit to some basic circuit, can help us learn munication principle. In this course design of high frequency lectures, I used the basic knowledge of design of wireless alarm system. In nowadays, citizens property safety get more and more attention, and alarm system can help people to protect his own possessions. I SanDianShi feedback with LC oscillators, rf follow circuit and highfrequency harmonic power amplifier design one a center frequency for 12MHz transmitter by highfrequency small signal amplifier related knowledge of design a soundlight alarm can have the receivers, will highfrequency learned in class most knowledge both use the high frequency, this to our learning this course will help a lot, also is very meaningful. Key word: alarm, rf follow circuit, highfrequency harmonic power amplifier, LC SanDianShi feedback oscillators, highfrequency small signa
