新型阻濾波器裝置
本專利技術(shù)涉及一種濾波器,具體涉及一種新型阻濾波器裝置。
技術(shù)介紹
由于無(wú)線通信系統(tǒng)的發(fā)展,微波頻段出現(xiàn)越來(lái)越相對(duì)擁擠的狀態(tài),頻帶資源劃分越來(lái)越精細(xì),噪聲、干擾、雜散等抑制度的要求也日益增加,帶阻濾波器用于在通信系統(tǒng)中濾除不需要的雜波和噪聲信號(hào),以提高系統(tǒng)性能。另外,帶阻濾波器用于系統(tǒng)的雜散測(cè)試,將載波信號(hào)抑制掉,測(cè)量在其他頻段的傳導(dǎo)雜散。目前帶阻濾波器主要有微帶形式和腔體結(jié)構(gòu)形式。從實(shí)現(xiàn)形式上來(lái)說(shuō),由于微帶形式諧振器的Q值低,基于微帶線的帶阻濾波器的通帶邊緣損耗較大。基于腔體結(jié)構(gòu)的帶阻濾波器,雖然Q值較高,損耗小,但是其結(jié)構(gòu)復(fù)雜,加工與設(shè)計(jì)成本高,且濾波器的裝配和調(diào)試誤差會(huì)影響濾波器的性能。
