Ukudicilela phansi isimangaliso sika-50 ohm coax: iqhawe elingabonakali lokuxhumana okungenamthungo

Emkhakheni omkhulu wezobuchwepheshe, kunompetha owodwa othule oqinisekisa ukuhanjiswa kwedatha okubushelelezi nokuxhumeka okungenaphutha kuzinhlelo eziningi zezicelo - amakhebuli we-50 ohm. Ngenkathi abaningi bangahle bangaboni, leli qhane elingenzi angasebenzi lidlala indima ebalulekile ezimbonini ezisukela ekuxhumaneni ngocingo kuya e-aerospace. Kule bhulogi, sizokwambula izimfihlakalo zekhebula le-50 ohm coaxial futhi sihlole imininingwane yalo yezobuchwepheshe, izinzuzo kanye nezinhlelo zokusebenza. Ake siqale lolu hambo ukuze luqonde izinsika zokuxhumana okungenamthungo!

Imininingwane yezobuchwepheshe nesakhiwo:

Ikhebula le-50 ohm coaxialUmugqa wokuhambisa onesimo sokuvinjwa kwama-50 ohms. Isakhiwo saso siqukethe izingqimba ezine eziphambili: umqhubi wesifundo sangaphakathi, i-dielectric insulator, isihlangu sensimbi kanye nokuvikela umfutho wangaphandle. Umqhubi wesifundo, ovame ukwenziwa ngethusi noma nge-aluminium, uphethe isibonakaliso sikagesi, kanti i-dielectric insulator isebenza njengomthakisi kagesi phakathi komqhubi wesifundo esiphakathi nesihlangu. Ukuvikelwa Kwensimbi, okungaba ngesimo socingo olunamafutha noma i-foil, kuvikela ngokumelene nokuphazamiseka kwangaphandle komsakazo (RFI). Ekugcineni, i-Sheath yangaphandle inikezela ukuvikela okwenziwe ngomshini kukhebula.

Izinzuzo ezembula:

1 Ibonisa i-attenuation ephansi (okusho ukuthi ukulahleka kwesiginali) kumabanga amade, okwenza kube lula ukuthola izicelo zemvamisa ephezulu. Lesi sici esincishisiwe esiphansi sibalulekile ekugcineni ukudluliswa kwesiginali okuthembekile nokwekhwalithi ephezulu.

2. Ububanzi obuvame ukuvama Lokhu kuguqulelwa kukwenza sikwazi ukufeza izidingo zezinhlelo zokusebenza ezahlukahlukene, kufaka phakathi ukuxhumana ngocingo, ukusakaza, ukuhlolwa kwe-RF nokulinganisa, ukuxhumana kwezempi kanye nomkhakha wezempi.

I-3. Ukuvikelwa okuqinile: Lolu hlobo lwekhebula lubonisa ukuvikelwa kwensimbi okuqinile okunikeza ukuvikela okuhle kakhulu ekuphazanyisweni kwama-elektromagnetic angafuneki futhi kuqinisekise ukuhanjiswa kwesiginali okuhlanzekile. Lokhu kwenza kube kuhle ngezicelo ezithambekele ku-RFI, njengezinhlelo zokuxhumana ezingenantambo kanye nokusetha okulinganiselwe okuphezulu.

Izicelo ezicebile:

1. Ukuxhumana ngocingo: Embonini yezingcingo zezokuxhumana, izintambo ezingama-50-ohm coaxial zisebenza njenge-backmbone yokudlulisela izwi, ividiyo, kanye nezimpawu zedatha phakathi kwemibhoshongo yezokuxhumana nokushintshwa. Kuvame ukusetshenziswa kumanethiwekhi amaselula, ukuxhumana kwe-satellite, kanye nabahlinzeki benkonzo ye-Intanethi (i-ISPS).

2 Isetshenziswa ezinhlelweni ze-radar, ama-avionics, ama-UAV (izimoto ezingekho emthethweni), amasistimu wokuxhumana wezempi, nokuningi.

I-3. Imishini Yezimboni Nezinto Zokuhlola: Ukusuka e-Oscilloscopes ku-Network Analyzers, ikhebula le-COAXIAL le-50-OHM livame ukusetshenziswa ezindaweni zokucwaninga kanye nemishini yezimboni. Amandla awo okudlulisa amasiginali aphezulu aphezulu ngokulahleka okuncane kwenza kube fanelekile ukuthola izicelo zokuhlola nokukalwa.

Ekuphetheni:

Yize kuvame ukunganakwa,Ikhebula le-50 ohm coaxialIngxenye ebalulekile kwizimboni eziningi, ukuqinisekisa ukuxhumeka okungenaphutha nokuhanjiswa kwedatha okuthembekile. Izici zayo eziphansi zokulahlekelwa, ukuvikelwa okuqinile nobubanzi obubanzi benza kube yingxenye ebaluleke kakhulu yezinhlelo zokusebenza zemvamisa ephezulu. Leli qhane elingesona lidlala indima ebalulekile kumanethiwekhi okuxhumana ngocingo, ubuchwepheshe be-aerospace, imishini yokuhlolwa kwezimboni kanye nezinye izinkambu. Ngakho-ke, ake sazise izimangaliso zekhebula le-50-ohm coaxial, i-aunt enabler yokuxhumana komthungo eminyakeni yedijithali.
