施主天線將接收到的基站下行信號(hào)送到雙工器，雙工器對(duì)信號(hào)進(jìn)行濾波后將上行信號(hào)送到低噪聲放大器進(jìn)行*級(jí)放大，放大后的信號(hào)含有雜散信號(hào)這時(shí)必需對(duì)信號(hào)再次進(jìn)行濾波，為了不影響后級(jí)的工作效率及對(duì)其它信號(hào)有好的抑制度，必須選擇一個(gè)有好的波形矩?cái)?shù)的濾波器才可以達(dá)到要求，在這么高的頻率一般普通的濾波器沒(méi)辦法達(dá)到要求，我們采用中頻頻段選擇器在中頻進(jìn)行濾波才可以達(dá)到要求。通過(guò)調(diào)整濾波器的中心工作頻率可使整個(gè)工作頻段上移或下移，這樣可根據(jù)現(xiàn)場(chǎng)的實(shí)際情況進(jìn)行靈活調(diào)整。將濾波后的信號(hào)送到大功率放大器進(jìn)行放大，zui后信號(hào)經(jīng)雙工器再次濾波后從重發(fā)天線發(fā)射出去對(duì)欲覆蓋區(qū)進(jìn)行信號(hào)覆蓋
