Mumakore achangopfuura, nechinangwa chekuchengetedza mari uye kuderedza kudzokororwa kwekuvaka, akawanda emukati ekugovera masisitimu atora modhi yeakawanda-akasanganiswa sisitimu inogovera kamuri nemamwe madiki-system. Izvi zvinoreva kuti akawanda-system uye akawanda-bhendi masaini anosanganiswa mukati meakajairwa musanganiswa mapuratifomu uye akagovaniswa emukati ekugovera masisitimu kuti awane akawanda-bhendi, akawanda-system, imwe-nzira, kana maviri-nzira kutapurirana.
Chakanakira kudzikisa kudzokororwa kwezvivakwa uye kuchengetedza nzvimbo. Zvisinei, matambudziko anokonzerwa nemaitiro akadaro ekugovera mukati ari kuwedzera kuoneka. Multi-system kugarisana zvinounza kukanganiswa kwe-inter-system. Kunyanya, mabhendi ekushanda ma frequency akafanana, uye mabhendi epakati madiki, spurious emission uye PIM pakati peasiyana masisitimu anokanganisa zvakare.
Mune ino kesi, yakanaka mhando passive mudziyo inogona kudzikisira mhedzisiro yekukanganisa uku. Iyo yakashata-yemhando yeRF passive mudziyo pachayo inozotungamira mukudzikira kwemamwe maratidziro etiweki, uye emhando yepamusoro michina ichave nemhedzisiro yakanaka pamhando yetiweki, kudzivirira kuitika kwekubuda kwenhema, kupindira, uye kuzviparadzanisa nevamwe.
Mhando huru dzekupindira mumatambo asina waya dzakakamurwa kuita in-system kupindira uye inter-system kupindira. In-system interference inoreva kurasika kwebhendi rekutumira, iro rinowira mukukanganiswa kwegadziriro pachayo inokonzerwa nebhendi rekugamuchira. Kupindira kweInter-system kunonyanya kuburitswa kwekunyepedzera, kugashira kugarwa, uye kukanganiswa kwePIM.
Zvichienderana netiweki yakajairwa uye mamiriro ekuyedza, passive zvishandiso chinhu chakakosha chinokanganisa ma network.
Zvinhu zvakakosha zvekugadzira yakanaka passive chikamu zvinosanganisira:
1. Kuzviparadzanisa nevamwe
Kusazviparadzanisa nevamwe kunokonzeresa kupindirana pakati pemasisitimu, kufambisa kwekurasika uye yakawanda-inotakura PIM, wozovhiringidza nechiratidzo chekumusoro.
2. VSWR
Muchiitiko cheVSWR yezvinongoita zvinhu zvakakura, iyo inoratidzwa chiratidzo inova hombe, muzviitiko zvakanyanyisa base chiteshi chinozoziviswa kukuvadzwa kwezvinhu zveRF uye amplifiers.
3. Kurambwa mukunze kwebhendi
Kurambwa kwakashata kwekunze-kwe-bhendi kuchawedzera kupindira kwe-inter-system, asi yakanaka yekunze-ye-bhendi inhibition kugona, uye yakanaka yekuzviparadzanisa nechiteshi ichabatsira kuderedza kupindira pakati pehurongwa.
4. PIM - passive Intermodulation
Zvigadzirwa zvakakura zvePIM zvinowira mubhendi rekumusoro zvinokonzeresa kuderera kwekuita kweanogamuchira.
5. Simba rakawanda
Panyaya yeakawanda-anotakura, yakakwira simba kubuda, uye yakakwirira peak reshiyo chiratidzo, kusakwana kwesimba simba kunotungamira kune yakakwira system mutoro. Izvi zvinokonzeresa kuti network yemhando idonhe zvakanyanya, izvo zvinokonzeresa arcing uye moto mamiriro. Muzviitiko zvakakomba, zvinokwanisika kupaza kana kupisa michina, zvichiita kuti base station network ipunzike.
6. Device processing process uye zvinhu
Material uye magadzirirwo maitiro haana kuvharwa, akananga kumudziyo parameter performance degradation, ukuwo kusimba kwechishandiso uye kuchinjika kwezvakatipoteredza kunoderedzwa zvakanyanya.
Pamusoro pezvinhu zvakakosha zviri pamusoro, pane zvimwe zvakajairika zvinotevera:
1. Kuisa kurasikirwa
Kuisa kurasikirwa pamusoro-kusangana kunoita kuti chiratidzo chishaye simba rakawanda pane chinongedzo chinokanganisa kuvharika, uku ichiwedzera yakananga chiteshi ichaunza kupindira kutsva, uye kungovandudza base chiteshi chekufambisa simba haina hushamwari kwezvakatipoteredza, uye kupfuura iyo amplifier mutsara wakakwana mutsara wekushandisa. apo iyo transmitter chiratidzo chemhando ichadzikira, ichakanganisa iyo inotarisirwa kuitika kwemukati yekugovera dhizaini.
2. Mu-bhendi kuchinja
Kuchinja kukuru kunozotungamira kune kushata flatness kweiyo-bhendi chiratidzo, kana paine akawanda anotakura anozovhara maitiro, uye kukanganisa kunotarisirwa kuitiswa kwemukati yekugovera dhizaini.
Naizvozvo, passive components zvinoita basa rakakosha mukuvaka kweae communication network base station.
Jingxin anotarisa pacustomizing the passive componentsinodiwa kune vatengi, ingave kubva pakuongorora kwekutanga, yepakati-temu dhizaini zano, kana kunonoka kugadzirwa kwemazhinji, isu tinonamatira kune mhando yekutanga, kupa masevhisi kune vatengi pasi rese.
