濾波器是由電容、電感和電阻組成的濾波電路。濾波器是對波進行過濾的器件,是一種讓某一頻帶內(nèi)信號通過,同時又阻止這一頻帶外信號通過的電路。什么是低通濾波器?看國創(chuàng)小編總結(jié)!

電源模塊是將其它形式的能轉(zhuǎn)換成電能的裝置。其工作原理是發(fā)電機能把機械能轉(zhuǎn)換成電能,干電池能把化學(xué)能轉(zhuǎn)換成電能。電源模塊常見故障排除如何排除呢?看國創(chuàng)小編整理分享!

現(xiàn)階段射頻濾波器市場還在迎來更多增長。這是因為,隨著4G的成熟和5G的來臨,手機支持的頻段數(shù)量正在上升。對于一個頻段而言,一般至少需要兩個濾波器,為此我們的濾波器市場前景廣闊,這既是機遇也是挑戰(zhàn),我們應(yīng)該抓住機會努力發(fā)展!

電源模塊紋波指標(biāo)是一項很重要的參數(shù)。干凈的電源是數(shù)字電路穩(wěn)定工作的前提,也是模擬器件的各項參數(shù)的重要保障。為確定電源的質(zhì)量,必須對電源模塊的輸出紋波進行測量。如何測量電源模塊的紋波?看國創(chuàng)小編分享!

LC濾波器由串聯(lián)電抗L和并聯(lián)電容C構(gòu)成;LCL濾波器是指濾波器的一種結(jié)構(gòu)形式,頭部是一組電感在串聯(lián),中間部分是并聯(lián)的安規(guī)電容,尾部又串聯(lián)了一組電感上去。

限幅二極管中限幅電路,就是指限制電路中某一點的信號幅度大小,當(dāng)信號幅度大到一定程度時,不讓信號的幅度再增大;當(dāng)信號的幅度沒有達到限制的幅度時,限幅電路不工作。

射頻濾波器最主要的指標(biāo)包括品質(zhì)因數(shù)Q和插入損耗。在目前的通訊協(xié)議中,不同頻帶間的頻率差越來越小,因此需要非常好選擇性,讓通帶內(nèi)的信號通過并阻擋通帶外的信號。

電源模塊是可以直接貼裝在電路板上的電源供應(yīng)器,其特點是可為專用集成電路、數(shù)字信號處理器、微處理器、存儲器、現(xiàn)場可編程門陣列及其他數(shù)字或模擬負(fù)載提供供電。
