電阻(zu)(zu)芯(xin)片的發(fa)(fa)現(xian)(xian)(xian)可以追溯(su)到1833年，英國科學家邁克(ke)爾·法拉第(MichaelFaraday)在(zai)測(ce)試硫化銀(Ag2S)的特(te)性(xing)時，發(fa)(fa)現(xian)(xian)(xian)它的電阻(zu)(zu)隨著溫度(du)的上升(sheng)而(er)降(jiang)低(di)。這是人(ren)類一次發(fa)(fa)現(xian)(xian)(xian)具有(you)電阻(zu)(zu)特(te)性(xing)的物質(zhi)，也(ye)就是半導(dao)體(ti)現(xian)(xian)(xian)象的發(fa)(fa)現(xian)(xian)(xian)。隨后，在(zai)1839年，法國科學家埃德蒙·貝克(ke)雷(lei)爾(EdmondBecquerel)發(fa)(fa)現(xian)(xian)(xian)半導(dao)體(ti)和電解(jie)質(zhi)接觸形成的結，在(zai)光(guang)(guang)照下會(hui)產(chan)生一個電壓(ya)，這就是后來人(ren)們熟知的光(guang)(guang)生伏特(te)反(fan)應，簡稱(cheng)光(guang)(guang)伏效(xiao)應。這是人(ren)類發(fa)(fa)現(xian)(xian)(xian)的半導(dao)體(ti)的第二個特(te)征。在(zai)后來的研(yan)究中，人(ren)們還發(fa)(fa)現(xian)(xian)(xian)了半導(dao)體(ti)的其他特(te)性(xing)，如(ru)光(guang)(guang)電導(dao)效(xiao)應和整流效(xiao)應。這些(xie)特(te)性(xing)的發(fa)(fa)現(xian)(xian)(xian)為(wei)后來的半導(dao)體(ti)研(yan)究和應用奠定了基礎。四川懸置微帶衰減芯(xin)片批發(fa)(fa)廠家如(ru)何利用電阻(zu)(zu)芯(xin)片實現(xian)(xian)(xian)信號(hao)衰減和阻(zu)(zu)抗匹(pi)配？

微波(bo)衰減片(pian)的(de)(de)(de)衰減原理(li)是基(ji)于磁(ci)(ci)性材料(liao)對電(dian)磁(ci)(ci)波(bo)的(de)(de)(de)吸收(shou)(shou)和散射作用。在(zai)鐵氧體等磁(ci)(ci)性材料(liao)中，電(dian)磁(ci)(ci)波(bo)會在(zai)材料(liao)內部(bu)產(chan)生磁(ci)(ci)致伸縮效(xiao)應和自然(ran)共振，導致電(dian)磁(ci)(ci)波(bo)能量被大量吸收(shou)(shou)。同(tong)(tong)時，磁(ci)(ci)性材料(liao)中的(de)(de)(de)電(dian)子在(zai)電(dian)磁(ci)(ci)場(chang)(chang)的(de)(de)(de)作用下會受到(dao)洛倫茲力，產(chan)生電(dian)流(liu)，這個(ge)電(dian)流(liu)又會產(chan)生新的(de)(de)(de)磁(ci)(ci)場(chang)(chang)，進一步(bu)增(zeng)強對電(dian)磁(ci)(ci)波(bo)的(de)(de)(de)吸收(shou)(shou)。因此(ci)，微波(bo)衰減片(pian)可以有(you)效(xiao)地衰減電(dian)磁(ci)(ci)波(bo)信號(hao)。根據應用需(xu)求，微波(bo)衰減片(pian)有(you)不同(tong)(tong)的(de)(de)(de)規格和性能參數。例如，頻率范圍(wei)從(cong)幾(ji)兆赫(he)(he)茲到(dao)幾(ji)百吉(ji)赫(he)(he)茲，衰減量從(cong)幾(ji)分貝到(dao)幾(ji)十分貝，帶寬從(cong)幾(ji)兆赫(he)(he)茲到(dao)幾(ji)十吉(ji)赫(he)(he)茲等。微波(bo)衰減片(pian)還具(ju)有(you)良好(hao)的(de)(de)(de)溫(wen)度(du)穩定(ding)性和機械強度(du)，可以在(zai)惡劣的(de)(de)(de)環(huan)境條件下工作。
