帶通濾波器是一種濾波器,它可以在一定的頻率范圍內(nèi)通過頻率分量,但將其他范圍內(nèi)的頻率分量衰減到非常低的水平,與帶阻濾波器的概念形成對(duì)比。

濾波器是對(duì)波進(jìn)行過濾的器件,是一種讓某一頻帶內(nèi)信號(hào)通過,同時(shí)又阻止這一頻帶外信號(hào)通過的電路。按所通過信號(hào)的頻段分為低通、高通、帶通、帶阻和全通濾波器五種。今天我們國(guó)創(chuàng)就來說說高通濾波器!

我們國(guó)創(chuàng)的固定式衰減器的阻抗規(guī)格分為50歐姆和75歐姆。這些固定式衰減器可與2.4mm、2.92mm、7/16 DIN、7mm、BNC、F型、N型、SMA和TNC連接器匹配。

肖特基二極管是由貴金屬(金、銀、鋁、鉑等)制成的金屬半導(dǎo)體器件。A作為正電極,N型半導(dǎo)體B作為負(fù)電極,并利用在兩者的接觸表面上形成的勢(shì)壘的整流特性。

帶通濾波器是一種僅允許特定頻率通過,同時(shí)對(duì)其余頻率的信號(hào)進(jìn)行有效抑制的電路。由于它對(duì)信號(hào)具有選擇性,故而被廣泛地應(yīng)用現(xiàn)在電子設(shè)計(jì)中。

軍工電源模塊就是電壓轉(zhuǎn)化設(shè)備之一,他主要功能是將交流電和直流電相互轉(zhuǎn)化,在某中程度上也可以說是一個(gè)帶負(fù)反饋的穩(wěn)壓系統(tǒng),性能指標(biāo)分為靜態(tài)指標(biāo)和動(dòng)態(tài)指標(biāo)!今天國(guó)創(chuàng)就說說軍工電源模塊靜態(tài)、動(dòng)態(tài)指標(biāo)。

微波放大器的增益指放大器輸出功率和輸入功率的比值,單位常用“dB”(分貝)來表示。放大器的輸出增益隨輸入信號(hào)頻率的變化而提升或衰減。對(duì)于電子線路中所標(biāo)稱的噪聲,可以概括地認(rèn)為,它是對(duì)目的信號(hào)以外的所有信號(hào)的一個(gè)總稱。

DC/DC模塊軍工電源是采用開關(guān)電源來實(shí)現(xiàn)的,其原理也是一樣。DC-DC模塊電源的優(yōu)點(diǎn)主要體現(xiàn)在體積小,轉(zhuǎn)換效率高,穩(wěn)定性好等特點(diǎn)。使用軍工電源模塊可節(jié)省開發(fā)時(shí)間,并使產(chǎn)品更快上市,因此電源模塊的性能優(yōu)于集成解決方案。主功率模塊還具有很多優(yōu)點(diǎn)!
