Radio frequencypassive componentsanonyanya kushandiswa mukuvaka mawireless communication system base stations, uye indoor kugovera masisitimu. Kunyanya mune isina waya chiratidzo muchivako, kune akawanda marudzi ekushandisa mune yemukati yekugovera yekuvhara.
Radio frequency passive zvikamu zvinotora basa mukubatanidza kana kugovera masaini eRF mukuvaka chiteshi chepasi uye mapurojekiti ekuparadzira mukati. Iyo yemukati yekugovera sisitimu inobatanidza kana kupatsanura chiratidzo chinofambiswa neiyo base chiteshi kuburikidza nezvinongoita zvinhu, uye inoiparadzira kune antennas ega ega yekuvhara nzvimbo kuburikidza neyekudyisa, kuitira kuti uwane inoenderera uye yakanaka kufukidzwa kwemukati isina waya chiratidzo. Kuti uwane zvirinani zvemukati mechiratidzo chekuvhara, iyi sisitimu yekugovera inobatanidza / inotsemura chiratidzo chinofambiswa kubva pachigadziko chiteshi kuenda kune yega yekuvhara nzvimbo yeantenna kuburikidza nezvinongoita zvinhu.
Passive zvishandiso ndizvo zvakakosha zveiyo antenna feeder system.
Classic antenna feeder system topology sezvinotevera:
Iwo maredhiyo frequency masaini emafomati akawanda anotumirwa nega yega chiteshi, iwo anosanganiswa neasina midziyo nekubatanidza mabasa akadai seakawanda-frequency musanganisi kana mabhiriji, obva aendeswa kune sirin'i antenna kana madziro emadziro akagoverwa muchivako chose kuburikidza netambo. Chiratidzo chakabatanidzwa chinogonawo kuvharwa zvakananga ne coupler, iyo inobatanidza chikamu chechiratidzo. Nekuda kwekushandisa zvimwe zvigadziriso, kurasikirwa kwekuiswa kweplug-in zvishandiso kunounganidza izvo zvinogona kukonzera kudzoreredzwa kwechiratidzo (kutumira masaini eRF madaro marefu, ayo anogona kuburitsa kudzoreredza kukuru panguva yekufambisa tambo.)
Iyo yakasanganiswa siginecha yakabatana kune inobuda chiteshi cheyakawanda-frequency musanganiswa semagetsi splitter (uchishandisa yakadzoserwa musanganiswa). Mushure mekunge chiratidzo chapepetwa neakawanda-frequency musanganiswa, inoburitswa nechiteshi chekupinza cheiyo yakawanda-frequency musanganiswa. Nekuda kwebhendi-pass kusefa maitiro echiteshi chega chega, aya madoko anongoburitsa chiratidzo mubhendi rekushanda rechiteshi chechiteshi chega chega.
Aya masaini anogona kuendeswa kune akasarudzika anodzokorora emhando dzakasiyana siyana: kukwidziridzwa, kubuda, kusanganiswa, uyezve kufukidzwa kubhadhara kurasikirwa uye kuderedzwa kwechiratidzo pane chinongedzo, uye pakupedzisira kusangana nemaparamita eiyo link bhajeti dhizaini kuve nechokwadi. kufukidzira mhedzisiro yechinhu chimwe nechimwe.
Saka semugadziri weRF passive components, Jingxin inogona kukutsigiragadzirisa zvinhu zvinongoitwamaererano nekushandiswa. Unogamuchirwa kuti utaure nesu. Ndatenda.
