RF coaxial connector chikamu chemagetsi chekubatanidza uye zvakare nzvimbo inopisa.Tevere, mainjiniya eCankemeng achaita sumo yehunyanzvi kune ruzivo rweRF coaxial yekubatanidza.
Mhedziso yeRF coaxial connectors:
Coaxial connector, (Vamwe vanhu vanodanawo kuti RF connector kana RF connector. Kutaura zvazviri, RF connector haina kunyatsofanana necoaxial connector. RF connector inoparadzaniswa kubva pamaonero ekushandiswa kwehuwandu hwekubatanidza, ukuwo coaxial connector inoparadzaniswa kubva Mamiriro ekubatanidza haafanire kunge ari coaxial, asi zvakare anoshandiswa mumunda weRF, uye coaxial chinongedzo chinogona zvakare kushandiswa muzasi frequency, semuenzaniso, yakajairika audio headphone plug, Iyo frequency haipfuuri 3MHz Kubva Maonero echinyakare, RF inoreva chikamu cheMHz Mazuva ano, coaxial zvinongedzo zvinowanzo shandiswa muchikamu che microwave, izwi rekuti "RF" rave richishandiswa nguva dzese uye rinopindirana neshoko rekuti "microwave"). iro rinova bazi rezvibatanidza.Pane kufanana uye kusiyana pakati pezvibatanidza.Coaxial connectors vane mukati maconductor uye ekunze conductors.Inner conductor inoshandiswa kubatanidza mutsara wechiratidzo.Iyo yekunze conductor haingori waya yepasi chete yemutsara wechiratidzo (inoratidzwa pamusoro pemukati wekunze conductor), asi zvakare inotamba basa rekudzivirira iyo electromagnetic field (kudzivirira kupindira kwemukati wemagetsi magineti kusvika kunze kuburikidza nemukati. pamusoro peiyo yekunze conductor, uye nekudzivirira kupindira kwekunze kwemagetsi emagetsi munda kusvika mukati kuburikidza nekunze kwekunze kweiyo conductor yekunze), Iyi ficha inopa coaxial yekubatanidza nzvimbo yakakura uye mabhenefiti echimiro.Iyo yekunze yepamusoro yemutungamiri wemukati uye mukati meiyo yekunze giraidhi reiyo coaxial chinongedzo ndeye cylindrical nzvimbo - muzviitiko zvakakosha, dzinowanzo kudiwa pakugadzirisa mechanical uye dzine axis yakafanana, saka dzinonzi coaxial connectors.Pakati pemhando dzinoverengeka dzetambo dzekutumira, coaxial tambo inoshandiswa zvakanyanya nekuda kweyakanaka mabhenefiti (yakareruka chimiro, yakakwirira nzvimbo kushandiswa, nyore kugadzira, yepamusoro yekufambisa kuita…), zvichikonzera kudikanwa kwekubatanidza coaxial tambo, uye coaxial chinongedzo chinoiswa.Nekuda kwemabhenefiti eiyo coaxial chimiro, kuenderera kwehunhu impedance ye (coaxial) yekubatanidza (ichienzaniswa nemamwe maatanidzi) inovimbiswa zviri nyore, kutapurirana kukanganisa uye kukanganisa (EMI) kwakadzikira, uye kurasikirwa kwekutapurirana kudiki, saka inenge inoshandiswa chete muredhiyo frequency uye microwave minda.Nekuti inenge yakanyatso shandiswa muhuwandu hwepamusoro, mamwe magetsi ekuita zvinodiwa zvakasiyana kubva kune mamwe ma-link
Performance index yeRF coaxial yekubatanidza
Kuita kwemagetsi eRF coaxial connector kunofanirwa kunge kuwedzeredzwa kweRF coaxial tambo, kana kukanganisa pachiratidzo chinofambiswa kunofanirwa kudzikiswa kana coaxial yekubatanidza yakabatana neiyo coaxial tambo.Naizvozvo, iyo hunhu impedance uye voltage yakamira wave ratio zviratidzo zvakakosha zveRF coaxial yekubatanidza.Iyo hunhu impedance yekubatanidza inosarudza iyo impedance mhando yetambo yakabatana nayo Iyo voltage yakamira wave ratio inoratidza iyo inofananidzwa nhanho yekubatanidza.
A. Characteristic impedance: chimiro chechimiro chetambo yekufambisa inotarirwa ne capacitance uye inductance yetambo yekufambisa, inoratidzira kugoverwa kwemagetsi uye magnetic field mumutsara wekutumira.Chero bedzi iyo yepakati yemutsetse wekutapurirana iri yunifomu, iyo hunhu impedance inogara iripo.Munguva yekufambisa kwemafungu, E/H inogara iripo.Iyo tambo yekutapurirana pachayo inosarudza hunhu hwayo impedance, uye hunhu impedance yakafanana kwese kwese pamutsetse wekutumira.Mune coaxial tambo kana coaxial connectors, hunhu impedance inotarirwa nehupamhi hwemukati wekunze conductor, dhayamita rekunze remukati conductor uye dielectric garandi yepakati pakati pemukati uye kunze conductors.Pane hukama hunotevera hwehuwandu.
B. Reflection coefficient: the ratio of reflected voltage to input voltage.Iyo yakakwirira kukosha, kushoma kuratidzwa simba, zviri nani kufananidzwa, padyo nehunhu impedance, uye zvirinani kuenderera mberi.
C. Voltage standing wave ratio: pachava nemhando mbiri dzemasaisai anopararira pamutsara wekutapurirana usina kufananidzwa, imwe ndeye chiitiko wave uye imwe inoratidzwa wave.Mune dzimwe nzvimbo, marudzi maviri emasaisai akaiswa pamusoro.Iwo masaisai akaiswa pamusoro haaparadziri achitevedza tambo yekufambisa, asi anomira.Mune mamwe mazwi, pane nguva dzose kune yakakura kana kuti shoma voltage pane chero ndege yereferensi.Masaisai akadai anonzi mafungu akamira.Iyo VSWR ireshiyo yehuwandu hweiyo voltage yekupinza uye inoratidzwa voltage kune mutsauko uripo pakati peiyo yekupinda voltage uye inoratidzwa voltage.Hukoshi uhwu hukuru kupfuura kana kuenzana na1, diki ndizvo zviri nani, uye ine hukama hwehuwandu nereferensi coefficient.
