Mumakore achangopfuura, nekukurumidza kukura kwekutaurirana kusina waya uye radar tekinoroji, kuitira kuti uvandudze kureba kwekutenderera kwehurongwa, zvinodikanwa kuwedzera simba rekutumira rehurongwa.Sechikamu cheiyo microwave system yese, RF coaxial connectors inoda kukwanisa kumirisana nezvinoda kutapurirana zvekugona kwesimba repamusoro.Panguva imwecheteyo, mainjiniya eRF anodawo kugara achiitisa bvunzo dzepamusoro-simba uye zviyero, uye microwave zvishandiso / zvikamu zvinoshandiswa pabvunzo dzakasiyana siyana zvinodawo kukwanisa kumira nesimba rakakura.Ndezvipi zvinhu zvinokanganisa simba remagetsi eRF coaxial connectors?Huyai tione
● Saizi yekubatanidza
Kune masaini eRF eiyo frequency yakafanana, mahombe ekubatanidza ane simba rakakura kushivirira.Semuenzaniso, saizi yepini yekubatanidza inobatana neiyo ikozvino kugona kweiyo connector, iyo yakanangana nesimba.Pakati peakasiyana anowanzo shandiswa RF coaxial connectors, 7/16 (DIN), 4.3-10, uye N-mhando yekubatanidza yakakura muhukuru, uye inoenderana pinhole saizi zvakare yakakura.Kazhinji, kushivirira kwesimba kweN-mhando yekubatanidza ndeye SMA 3-4 nguva.Pamusoro pezvo, N-mhando yekubatanidza ndiyo inonyanya kushandiswa, ndosaka akawanda anongomira senge attenuators uye anotakura pamusoro pe200W ari N-mhando yekubatanidza.
●Kushanda kakawanda
Iko kushivirira kwesimba kweRF coaxial connectors kunoderera sezvo frequency yechiratidzo ichiwedzera.Shanduko mune yekufambisa chiratidzo frequency yakanangana nekuchinja mukurasikirwa uye voltage yakamira wave ratio, zvichikanganisa simba rekutapurirana uye ganda mhedzisiro.Semuenzaniso, general SMA connector inogona kumira kusvika 500W yesimba pa2GHz, uye avhareji simba inogona kumira isingasviki 100W pa18GHz.
●Voltage standing wave ratio
Iyo RF yekubatanidza inotsanangura humwe hurefu hwemagetsi panguva yekugadzira.Mune mutsara-urefu-urefu, kana hunhu hwekudzivirira uye mutoro wekudzivirira hauna kuenzana, chikamu chevoltage uye yazvino kubva kumagumo emutoro inoratidzwa kumashure kudivi remagetsi, iro rinonzi wave.Reflected masaisai;voltage uye ikozvino kubva kunobva kune mutoro anonzi chiitiko masaisa.Mhedzisiro yemafungu echiitiko uye masaisai anotaridzwa anodaidzwa kunzi stand wave.Chiyero cheyakanyanya voltage kukosha uye hushoma kukosha kweiyo yakamira wave inodaidzwa kuti voltage standing wave ratio (inogona zvakare kuve yakamira wave coefficient).Iyo inoratidzwa wave inogara pane chiteshi chemagetsi nzvimbo, zvichiita kuti simba rekufambisa rideredzwe.
●Kuisa kurasikirwa
Kurasika kwekupinza (IL) kunoreva kurasikirwa kwesimba pamutsetse nekuda kwekuunzwa kweRF zvibatanidza.Inotsanangurwa sereshiyo yesimba rinobuda kune simba rekuisa.Pane zvinhu zvakawanda zvinowedzera kurasikirwa kwekubatanidza kuisa kurasikirwa, zvakanyanya kukonzerwa ne: kusapindirana kwehunhu impedance, kukanganisa kwekusangana kwegungano, kukwirisa kuguma kwechiso gap, axis tilt, lateral offset, eccentricity, kugadzirisa kurongeka uye electroplating, etc. Nekuda kwekuvapo kwekurasikirwa, pane musiyano pakati pekuisa uye kubuda simba, izvo zvichakanganisawo simba rekumira.
●Altitude air pressure
Shanduko mukudzvinyirirwa kwemhepo kunokonzera shanduko mune dielectric nguva dzose yechikamu chemhepo, uye pakumanikidzwa kwakadzika, mhepo inogadzirwa nyore ionized kuburitsa corona.Iyo yakakwirira yekukwirira, kuderera kwemhepo yemhepo uye kudiki simba resimba.
●Bata kuramba
Kupokana kwekubata kweRF chinongedzo kunoreva kupokana kwenzvimbo dzekusangana dzemukati nekunze conductor kana chinongedzo chabatanidzwa.Iyo inowanzo iri mumillionhm level, uye kukosha kunofanira kuva kudiki sezvinobvira.Inonyanya kuongorora maitiro emagetsi evanoshamwaridzana, uye migumisiro yekudzivirira kwemuviri uye solder joint resistance inofanira kubviswa panguva yekuyera.Kuvapo kwekupokana kwekubata kuchaita kuti vanobatika vadziye, zvichiita kuti zviome kuendesa masaini makuru emagetsi microwave.
●Joint materials
Mhando imwechete yekubatanidza, uchishandisa zvinhu zvakasiyana, ichava nekusiyana kwesimba kushivirira.
Kazhinji, nokuda kwesimba re antenna, funga nezvesimba rayo pacharo uye simba rekubatanidza.Kana pane kudiwa kwesimba repamusoro, unogonacustomizesimbi isina tsvina yekubatanidza, uye 400W-500W haisi dambudziko.
