壓控振蕩器應用領域

主要應(ying)用于(yu)電(dian)(dian)子領(ling)(ling)域，壓(ya)控(kong)振(zhen)(zhen)蕩(dang)(dang)器(qi)(qi)生產廠家，由于(yu)其(qi)(qi)頻(pin)率(lv)(lv)范圍(wei)廣(guang)泛(fan)（1.25MHZ-80MHZ）故壓(ya)控(kong)振(zhen)(zhen)蕩(dang)(dang)器(qi)(qi)的應(ying)用極為廣(guang)泛(fan)，七專級壓(ya)控(kong)振(zhen)(zhen)蕩(dang)(dang)器(qi)(qi)生產廠家，如彩色(se)電(dian)(dian)視機高頻(pin)頭(tou)中(zhong)(zhong)的本機振(zhen)(zhen)蕩(dang)(dang)電(dian)(dian)路(lu)、各種自動頻(pin)率(lv)(lv)控(kong)制(AFC)系統中(zhong)(zhong)的振(zhen)(zhen)蕩(dang)(dang)電(dian)(dian)路(lu)、鎖相(xiang)環(huan)路(lu)(PLL)中(zhong)(zhong)所用的振(zhen)(zhen)蕩(dang)(dang)電(dian)(dian)路(lu)等(deng)均為壓(ya)控(kong)振(zhen)(zhen)蕩(dang)(dang)器(qi)(qi)。尤其(qi)(qi)在(zai)通(tong)信系統電(dian)(dian)路(lu)中(zhong)(zhong)，壓(ya)控(kong)振(zhen)(zhen)蕩(dang)(dang)器(qi)(qi)(VCO)是(shi)其(qi)(qi)關鍵(jian)部件(jian)，特別是(shi)在(zai)鎖相(xiang)環(huan)電(dian)(dian)路(lu)、時(shi)鐘恢復電(dian)(dian)路(lu)和頻(pin)率(lv)(lv)綜(zong)合器(qi)(qi)電(dian)(dian)路(lu)等(deng)更是(shi)重(zhong)中(zhong)(zhong)之重(zhong)，可以毫(hao)不夸張地說在(zai)電(dian)(dian)子通(tong)信技(ji)術領(ling)(ling)域，VCO幾(ji)乎與電(dian)(dian)流源(yuan)和運(yun)放具有同(tong)等(deng)重(zhong)要地位。

壓控振蕩器簡介

壓控振蕩器(qi)(qi)（VCO）是許多可(ke)調(diao)通信(xin)、無線電(dian)(dian)、雷達(da)、傳感和測(ce)量系統的(de)(de)(de)關鍵元件(jian)。VCO本(ben)質上是由輸入(ru)電(dian)(dian)壓（通常為模擬電(dian)(dian)壓）控制的(de)(de)(de)振蕩器(qi)(qi)。因此，七專(zhuan)級壓控振蕩器(qi)(qi)生產廠(chang)家，在整個可(ke)調(diao)范圍內調(diao)節調(diao)諧電(dian)(dian)壓可(ke)以成(cheng)比例地改變(bian)VCO的(de)(de)(de)輸出(chu)射頻(pin)信(xin)號。 VCO是鎖相環路、函(han)數(shu)發生器(qi)(qi)、頻(pin)率(lv)合成(cheng)器(qi)(qi)、雷達(da)、本(ben)地振蕩器(qi)(qi)（LO）中的(de)(de)(de)關鍵元件(jian)，同時(shi)也是頻(pin)率(lv)可(ke)調(diao)頻(pin)率(lv)發生器(qi)(qi)測(ce)試和測(ce)量設備中的(de)(de)(de)關鍵元件(jian)。

壓控振蕩器的性能參數

VCO的關(guan)(guan)鍵性(xing)能(neng)(neng)參數是調(diao)諧(xie)(xie)(xie)電(dian)(dian)壓、頻率(lv)(lv)(lv)范圍、本(ben)底噪聲、相位噪聲、輸(shu)出(chu)功(gong)(gong)率(lv)(lv)(lv)、諧(xie)(xie)(xie)波(bo)和負載阻抗。其(qi)次要性(xing)能(neng)(neng)參數包括(kuo)電(dian)(dian)源電(dian)(dian)壓、電(dian)(dian)源電(dian)(dian)流、調(diao)諧(xie)(xie)(xie)靈敏度、推頻、牽引、調(diao)諧(xie)(xie)(xie)端口電(dian)(dian)容和機械事項。調(diao)諧(xie)(xie)(xie)靈敏度用于說明調(diao)諧(xie)(xie)(xie)電(dian)(dian)壓（MHz/V）變化引起的輸(shu)出(chu)頻率(lv)(lv)(lv)變化。值得注意的是輸(shu)出(chu)功(gong)(gong)率(lv)(lv)(lv)和諧(xie)(xie)(xie)波(bo)功(gong)(gong)率(lv)(lv)(lv)與(yu)輸(shu)入(ru)直流功(gong)(gong)率(lv)(lv)(lv)和調(diao)諧(xie)(xie)(xie)電(dian)(dian)壓之間存在關(guan)(guan)系(xi)，但是不(bu)一定存在線(xian)性(xing)關(guan)(guan)系(xi)。
