11、PIN 型二(er)极(ji)(ji)(ji)管（PIN Diode）这是(shi)在 P 区(qu)(qu)和 N 区(qu)(qu)之间夹一层本征(zheng)(zheng)半导体(ti)（或(huo)低浓(nong)度杂质的半导体(ti)）构造(zao)的晶体(ti)二(er)极(ji)(ji)(ji)管。PIN 中的 I 是(shi)“本征(zheng)(zheng)”意义的英文略语。当其工作频(pin)率超过(guo) 100MHz 时，由于少数载流(liu)子的存贮效应和“本征(zheng)(zheng)”层中的渡越时间效应，其二(er)极(ji)(ji)(ji)管失去整流(liu)作用而(er)变成阻抗元(yuan)(yuan)件，并且(qie)，其阻抗值随偏(pian)(pian)置电压而(er)改变。在零(ling)偏(pian)(pian)置或(huo)直流(liu)反向偏(pian)(pian)置时，“本征(zheng)(zheng)”区(qu)(qu)的阻抗很高(gao)；在直流(liu)正向偏(pian)(pian)置时，由于载流(liu)子注入“本征(zheng)(zheng)”区(qu)(qu)，而(er)使(shi)“本征(zheng)(zheng)”区(qu)(qu)呈(cheng)现出低阻抗状(zhuang)态。因此(ci)，可(ke)(ke)以(yi)把 PIN 二(er)极(ji)(ji)(ji)管作为(wei)可(ke)(ke)变阻抗元(yuan)(yuan)件使(shi)用。它常被应用于高(gao)频(pin)开关(guan)（即微(wei)波(bo)开关(guan)）、移相、调制、限幅等电路(lu)中。深圳市凯轩业(ye)科技有限公司专(zhuan)业(ye)设计肖特(te)基二(er)极(ji)(ji)(ji)管研(yan)究(jiu)生产价格优势，品(pin)质专(zhuan)业(ye)，欢迎(ying)咨询。山东肖特(te)基二(er)极(ji)(ji)(ji)管采购
