ATOS放大器主要作用
1、ATOS放(fang)大器能把(ba)輸入(ru)訊號的電壓或功率放(fang)大的裝置，由(you)電子管或晶體管、電源變壓器和其他電器元件組成。用在通訊、廣播、雷(lei)達、電視、自(zi)動控制等各種裝置中。
ATOS放大器原理(li): 高(gao)頻功(gong)率放大器用于發射機的末級，作用是將(jiang)高(gao)頻已調波(bo)信(xin)號進行功(gong)率放大，以滿足發送功(gong)率的要(yao)求，然后(hou)經過天(tian)線(xian)將(jiang)其輻射到空間，保(bao)證在(zai)一定(ding)區(qu)域內(nei)的接(jie)收機可以接(jie)收到滿意(yi)的信(xin)號電平(ping)，并且不干擾相鄰信(xin)道(dao)的通信(xin)。
ATOS放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)是通(tong)(tong)(tong)信系統(tong)中(zhong)發送裝置的(de)(de)(de)重(zhong)要組件。按其工(gong)作(zuo)(zuo)(zuo)頻(pin)帶(dai)(dai)的(de)(de)(de)寬(kuan)窄劃分(fen)為(wei)(wei)窄帶(dai)(dai)高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)和寬(kuan)帶(dai)(dai)高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)兩種，窄帶(dai)(dai)高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)通(tong)(tong)(tong)常以具(ju)有(you)(you)選(xuan)頻(pin)濾波(bo)作(zuo)(zuo)(zuo)用(yong)的(de)(de)(de)選(xuan)頻(pin)電(dian)(dian)(dian)路(lu)作(zuo)(zuo)(zuo)為(wei)(wei)輸(shu)出回(hui)路(lu)，故又稱為(wei)(wei)調(diao)(diao)諧(xie)(xie)(xie)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)或諧(xie)(xie)(xie)振功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)；寬(kuan)帶(dai)(dai)高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)的(de)(de)(de)輸(shu)出電(dian)(dian)(dian)路(lu)則是傳輸(shu)線變(bian)壓器(qi)(qi)(qi)(qi)或其他寬(kuan)帶(dai)(dai)匹配(pei)電(dian)(dian)(dian)路(lu)，因此又稱為(wei)(wei)非調(diao)(diao)諧(xie)(xie)(xie)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)。高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)是一種能量(liang)轉換器(qi)(qi)(qi)(qi)件，它(ta)將電(dian)(dian)(dian)源供給的(de)(de)(de)直流(liu)(liu)(liu)(liu)能量(liang)轉換成為(wei)(wei)高(gao)(gao)頻(pin)交流(liu)(liu)(liu)(liu)輸(shu)出在 “低頻(pin)電(dian)(dian)(dian)子線路(lu)”課程中(zhong)已知，放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)可以按照電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)導(dao)通(tong)(tong)(tong)角(jiao)的(de)(de)(de)不同，將其分(fen)為(wei)(wei)甲、乙(yi)、丙(bing)(bing)(bing)(bing)三(san)類工(gong)作(zuo)(zuo)(zuo)狀(zhuang)態。甲類放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)流(liu)(liu)(liu)(liu)通(tong)(tong)(tong)角(jiao)為(wei)(wei)360o，適(shi)用(yong)于(yu)小信號低功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)。乙(yi)類放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)流(liu)(liu)(liu)(liu)通(tong)(tong)(tong)角(jiao)約等于(yu) 180o；丙(bing)(bing)(bing)(bing)類放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)的(de)(de)(de)流(liu)(liu)(liu)(liu)通(tong)(tong)(tong)角(jiao)則小于(yu)180o。乙(yi)類和丙(bing)(bing)(bing)(bing)類都適(shi)用(yong)于(yu)大(da)(da)(da)(da)(da)(da)功(gong)(gong)(gong)(gong)率(lv)(lv)工(gong)作(zuo)(zuo)(zuo)丙(bing)(bing)(bing)(bing)類工(gong)作(zuo)(zuo)(zuo)狀(zhuang)態的(de)(de)(de)輸(shu)出功(gong)(gong)(gong)(gong)率(lv)(lv)和效率(lv)(lv)是三(san)種工(gong)作(zuo)(zuo)(zuo)狀(zhuang)態中(zhong)zui高(gao)(gao)者。高(gao)(gao)頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)大(da)(da)(da)(da)(da)(da)多工(gong)作(zuo)(zuo)(zuo)于(yu)丙(bing)(bing)(bing)(bing)類。但丙(bing)(bing)(bing)(bing)類放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)器(qi)(qi)(qi)(qi)的(de)(de)(de)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)波(bo)形失真太(tai)大(da)(da)(da)(da)(da)(da)，因而(er)不能用(yong)于(yu)低頻(pin)功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)，只能用(yong)于(yu)采用(yong)調(diao)(diao)諧(xie)(xie)(xie)回(hui)路(lu)作(zuo)(zuo)(zuo)為(wei)(wei)負載的(de)(de)(de)諧(xie)(xie)(xie)振功(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)(fang)(fang)(fang)大(da)(da)(da)(da)(da)(da)。由于(yu)調(diao)(diao)諧(xie)(xie)(xie)回(hui)路(lu)具(ju)有(you)(you)濾波(bo)能力(li)，回(hui)路(lu)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)與電(dian)(dian)(dian)壓仍然(ran)極近于(yu)正弦波(bo)形，失真很小。
ATOS放大器基本結構:
ATOS放大(da)器輸入(ru)待測信(xin)號，經放大(da)和帶通(tong)濾波后(hou)與參考(kao)信(xin)號共同輸入(ru)乘(cheng)法器得(de)到的結(jie)果再通(tong)過(guo)低通(tong)濾波器濾波后(hou)輸出。
ATOS放大器主(zhu)要原理(li):
鎖相放大器實(shi)際(ji)上是一(yi)個模擬的傅立葉變換器，鎖相放大器的輸(shu)出(chu)是一(yi)個直流電(dian)壓(ya)，正比于(yu)是輸(shu)入信(xin)號中(zhong)(zhong)某一(yi)特定(ding)頻(pin)率（參數輸(shu)入頻(pin)率）的信(xin)號幅(fu)值。而輸(shu)入信(xin)號中(zhong)(zhong)的其(qi)他頻(pin)率成分將不能(neng)對(dui)輸(shu)出(chu)電(dian)壓(ya)構成任何貢獻。
兩個正弦信號(hao)，頻(pin)率都為1Hz，有90度相位差，用乘法器相乘得到的(de)結果是一個有直流偏量的(de)正弦信號(hao)。
如果(guo)是一個1Hz和(he)一個1.1Hz的(de)(de)信(xin)號相(xiang)乘，用乘法器相(xiang)乘得到的(de)(de)結果(guo)是輪廓為(wei)正弦的(de)(de)調(diao)制(zhi)信(xin)號，直流偏量為(wei)0。
只有與參考信號頻率*一致的信號才能在乘法器輸出端得到直流偏量，其他信號在輸出端都是交流信號。如果在乘法器的輸出端加一個低通濾波器，那么所有的交流信號分量全部被濾掉，剩下的直流分量就只是正比于輸入信(xin)(xin)號中的特定(ding)頻率的信(xin)(xin)號分量的幅值。
ATOS放大器主要用途:
ATOS放大器主要用于檢測(ce)信(xin)(xin)(xin)噪比很(hen)低的(de)(de)微弱信(xin)(xin)(xin)號(hao)(hao)(hao)。即使(shi)有用的(de)(de)信(xin)(xin)(xin)號(hao)(hao)(hao)被(bei)淹沒(mei)在噪聲信(xin)(xin)(xin)號(hao)(hao)(hao)里面(mian)，即使(shi)噪聲信(xin)(xin)(xin)號(hao)(hao)(hao)比有用的(de)(de)信(xin)(xin)(xin)號(hao)(hao)(hao)大很(hen)多(duo)，只要知道有用的(de)(de)信(xin)(xin)(xin)號(hao)(hao)(hao)的(de)(de)頻率值(zhi)，就能準(zhun)確地測(ce)量出這個(ge)信(xin)(xin)(xin)號(hao)(hao)(hao)的(de)(de)幅值(zhi)。
