信號放大器的簡介：

信號放大器是shi微wei型xing中zhong繼ji器qi，也ye稱cheng為wei移yi動dong信xin號hao放fang大da器qi或huo移yi動dong電dian話hua伴ban侶lv。我wo們men從cong名ming稱cheng中zhong知zhi道dao信xin號hao放fang大da器qi功gong能neng是shi以yi放fang大da信xin號hao為wei主zhu。有you許xu多duo類lei型xing的de信xin號hao放fang大da器qi
，例li如ru電dian視shi信xin號hao放fang大da器qi，無wu線xian電dian放fang大da器qi等deng。所suo有you接jie收shou器qi都dou具ju有you信xin號hao放fang大da器qi。專zhuan門men放fang大da手shou機ji信xin號hao的de放fang大da器qi稱cheng為wei蜂feng窩wo電dian話hua信xin號hao放fang大da器qi
，主zhu要yao用yong於yu解jie決jue室shi內nei手shou機ji信xin號hao盲mang點dian的de問wen題ti。

作為實現“小容量和大覆蓋範圍”目mu標biao的de必bi要yao手shou段duan之zhi一yi，使shi用yong中zhong主zhu要yao是shi使shi用yong為wei了le確que保bao網wang絡luo覆fu蓋gai而er不bu增zeng加jia基ji站zhan的de數shu量liang，並bing且qie成cheng本ben遠yuan低di於yu此ci現xian有you的de。微wei蜂feng窩wo係xi統tong的de效xiao果guo。中zhong繼ji器qi是shi解jie決jue通tong信xin網wang絡luo的de擴kuo展zhan覆fu蓋gai能neng力li的de首shou選xuan解jie決jue方fang案an。與yu基ji站zhan相xiang比bi
，結jie構gou簡jian單dan
，投tou資zi較jiao少shao，安an裝zhuang方fang便bian的de優you點dian。它ta可ke以yi廣guang泛fan應ying用yong於yu盲mang目mu和he弱ruo勢shi區qu域yu，難nan以yi覆fu蓋gai
，如ru購gou物wu中zhong心xin，酒jiu店dian，機ji場chang

，碼ma頭tou，站zhan，體ti育yu場chang，娛yu樂le大da廳ting
，地di鐵tie
，隧sui道dao，在zai公gong路lu和he島dao嶼yu等deng各ge個ge地di方fang，改gai善shan了le溝gou通tong質zhi量liang
，解jie決jue呼hu叫jiao的de問wen題ti，並bing優you化hua無wu線xian通tong信xin網wang絡luo。

信號放大器的傳輸方式

在zai中zhong繼ji器qi的de下xia行xing鏈lian路lu中zhong，主zhu天tian線xian在zai基ji站zhan的de現xian有you覆fu蓋gai區qu域yu中zhong拾shi取qu信xin號hao，並bing將jiang帶dai子zi外wai部bu的de信xin號hao隔ge離li通tong過guo帶dai通tong濾lv波bo器qi。通tong過guo功gong率lv放fang大da器qi放fang大da濾lv波bo器qi信xin號hao，然ran後hou再zai次ci發fa送song到dao要yao覆fu蓋gai的de區qu域yu。在zai上shang行xing鏈lian路lu路lu徑jing中zhong，覆fu蓋gai區qu域yu中zhong的de移yi動dong台tai的de移yi動dong電dian話hua信xin號hao由you上shang行xing鏈lian路lu放fang大da鏈lian路lu以yi相xiang同tong的de工gong作zuo方fang式shi處chu理li
，然ran後hou發fa送song到dao相xiang應ying的de基ji站zhan，以yi便bian實shi現xian基ji站zhan和he基ji站zhan之zhi間jian的de信xin號hao傳chuan輸shu手shou機ji。
