Coaxial RF majoini akakosha eRF kutapurirana zvikamu mumunda wemicrowave uye anoshandiswa zvakanyanya mune akasiyana microwave zvishandiso / zvikamu, microwave yekutaurirana michina, zviridzwa uye radar masisitimu.
RF coaxial yekubatanidza mhando: Nekukurumidza kusimudzira kweasina waya kutaurirana uye radar tekinoroji mumakore achangopfuura, kuwedzera sisitimu yekufambisa mhando inoda kuwedzera sisitimu yekufambisa simba. Sechikamu chese microwave system, maRF coaxial connectors anofanirwa kukwanisa kushingirira-zvinodiwa zvekufambiswa kwemagetsi. Mainjiniya eRF vanowanzoitawo-magetsi ekuyeresa uye kuyerwa, uye midziyo yemicrowave yakasiyana-siyana nezvikamu zvinoshandiswa pakuongorora zvinodawo simba guru-. Izvi zvinogadzira kuwedzera kwakakwira kudiwa pasimba remagetsi eRF coaxial connectors, chiratidzo chakakosha cheRF coaxial yekubatanidza mhando. Saka, yakawanda sei iwe yaunoziva nezve simba remagetsi eRF coaxial connectors? Simba resimba reRF coaxial connectors inyaya yakaoma, inopesvedzerwa nezvakawanda zvinhu, zvimwe zvacho zvinodyidzana. Izvi zvinhu zvinonyanya zvinosanganisira saizi yekubatanidza (kusanganisira pinhole saizi), mafambisirwo ekushanda, zvinhu zvemuviri, insulation zvinhu, kuvimbika kwekubata, kubata kuramba, voltage standing wave ratio (VSWR), ambient tembiricha, uye urefu. Mufananidzo uri pazasi unoratidza Megaphase yakakurudzirwa simba simba kukosha kune akasiyana maRF maabatanidza pama frequency akasiyana. Paunenge uchigadzira zvigadzirwa zveRF, unogona kusarudza iyo yakakodzera yekubatanidza zvichienderana neiyo chigadzirwa chekushanda frequency uye simba rekubata simba.
Tevere, isu tinopa tsananguro yakadzama yezvinhu zvinopesvedzera simba remagetsi eRF coaxial connectors. Kune ma RF masaini eiyo frequency yakafanana, mahombe ekubatanidza ane epamusoro masimba ekubata masimba. Semuyenzaniso, yekubatanidza pinhole saizi ine hukama neiyo yekubatanidza kugona, iyo yakanangana nesimba. Pakati pezvinowanzo shandiswa RF coaxial connectors, 7/16 (DIN), 4.3-10, uye N-mhando dzekubatanidza dzakati kurei, dzinoenderana nehukuru hwepinhole. Kazhinji, simba rekubata kweN{10}}chibatanidza chemhando inokwana katatu kana kana pane reSMA. Uku kwakawedzera kukurumbira kweN-zvikonikoni zvemhando zvinotsanangura kuti sei ruzhinji rwezvinhu zvinongotengeswa pamusika, zvakaita semaattenuators nemitoro ine simba rinopfuura 200W, vachishandisa N{16}}majoini emhando. RFbuy (www.rfbuy.com) inopa mukana nyore kune-makuro emagetsi akakwirira, maattenuators, uye mamwe maemusitirimu emicrowave. Simba rekubata simba reRF coaxial connectors rinodzikira nekuwedzera kwemasaini frequency. Shanduko mukufambiswa kwemasaini frequency inokanganisa kutapurirana kurasikirwa uye voltage yakamira wave ratio (VSWR), iyo inozokanganisa simba rekutapurirana. Uyezve, migumisiro yeganda inogonawo kuvapo. Semuenzaniso, yakajairwa SMA yekubatanidza ine simba rekubata simba ringangoita 500W pa2GHz, asi avhareji simba rekubata simba risingasviki 100W pa18GHz. Zvinoenderana neRFbuy RF Mall (www.rfbuy.com), akawanda mafungu, senge attenuators uye mitoro, inoshanda pama frequency ari pamusoro pe18 GHz ine avhareji yesimba rereti isingasviki 100 W. Kune mamillimeter wave frequencies, 1.85mm 67 GHz yakagadziriswa attenuator, uye isingasviki 5mm 7 W. GHz mutoro une avhareji yesimba reyerero isingasviki 22 W. A yakafara kusarudzwa 2.92mm attenuators uye mitoro iripo, ane avhareji simba ratings kusvika 100 W. RF connectors akagadzirwa ane yakatarwa magetsi kureba. Mune inogumira-mutsetse weurefu, kana chimiro chekuvhiringidza uye kusamira kwemutoro zvisina kuenzana, chikamu chevoltige uye chazvino kubva pamutoro chinoratidzwa kumashure kune magetsi. Save iyi inodaidzwa kuti reflection wave, ukuwo voltage nezvino kubva pamagetsi kuenda kumutoro zvinodaidzwa kuti chiitiko wave. Mafungu akabatanidzwa echiitiko uye masaisai anoratidzwa anonzi mafungu akamira. Huyero hwehukuru uye hudiki voltage kukosha kweiyo yakamira wave inonzi voltage standing wave ratio (inozivikanwawo seyakamira wave coefficient). Masaisai akaratidzira anotora chiteshi chemagetsi, kuderedza kutapurirana simba rekutapurirana. Insertion kurasikirwa (IL) inoreva kurasikirwa kwesimba mumutsara kunokonzerwa nekuunzwa kweRF yekubatanidza. Inotsanangurwa sereshiyo yesimba rekubuda kune simba rekupinza. Zvinhu zvakawanda zvinobatsira pakurasikirwa kwekubatanidza, zvinosanganisira kusapindirana kwehunhu, kukanganisa kwegungano, kupera kwekubatana -kujeka kwechiso, kurereka kweaxis, lateral offset, eccentricity, machining accuracy, uye plating. Kurasikirwa kunogadzira mutsauko pakati pekupinza uye kubuda simba, izvo zvinokanganisawo kubata simba. Kuchinja kwemhepo kunoshanduka pakakwirira kunokonzera kusiyana kwe dielectric nguva dzose yezvikamu zvemhepo, uye pakumanikidzwa kwakaderera, mhepo inonyanya kukonzerwa neionization, inogadzira corona. Iyo yakakwirira yakakwirira uye yakadzika mhepo yemhepo, iyo yakaderera simba rekubata simba. Bata kuramba: Kuramba kwekubata kweRF chinongedzo kunoreva kupokana panzvimbo yekubatana pakati pemukati nekunze makondakita kana chinongedzo chabatanidzwa. Inowanzoyerwa mumamiliohms uye inofanira kuchengetwa yakaderera sezvinobvira. Iyo inonyanya kuongorora maitiro emagetsi evanobatika, uye mhedzisiro yekupokana kwakawanda uye solder joint resistance inofanira kubviswa panguva yekuyera. Kubata kuramba kunokonzeresa kupisa kune vanobatika, zvichiita kuti zviome kufambisa masaini ane simba re microwave. Connector zvinhu: Simba rekubata simba reiyo imwechete yekubatanidza rinogona kusiyana zvichienderana nemidziyo inoshandiswa.
