I-adaptha ye-coaxial isiza ukuxhuma izinhlobo ezahlukene zamakhebuli angama-coaxial noma ukushintsha phakathi kwezixhumi zesilisa nesifazane. Abantu bayisebenzisela ukuthumela noma ukwamukela{1}}amasignali amaza aphezulu. Ubona lezi zinto kakhulu ezinhlelweni zamanje zokuxhumana namathuluzi okuhlola. Ziza ngazo zonke izinhlobo zezitayela. Isibonelo, kunezinhlobo ze-SMA zesilisa kuya ku-SSMA zabesifazane. Bese uba no-N-uhlobo oluthile. Ngayinye ilingana namaleveli athile okuvama kanye nokusetshenziswa.
I. Incazelo ye-Coaxial Adapter
I-adaptha ye-coaxial ikuvumela ukuthi uxhume izintambo ze-coaxial noma izixhumi. Ishintsha kakhulu izinhlobo ze-interface noma izici ze-impedance noma izidingo zokuxhuma. Lokhu kusetha kulandela indlela amakhebuli angama-coaxial asebenza ngayo. Igcina amasignali{3}emvamisa aphezulu engashintshi. Amakhondaktha angaphakathi nangaphandle kanye nezinto zokuvikela ukushisa kwenza lokho kwenzeke.
II. Imisebenzi ye-Coaxial Adapter
(I) Ukufanisa Impedans
Ukufanisa i-impedance kugqama njengomsebenzi obalulekile kulawa ma-adaptha. Ukuphazamiseka kwesici sekhebula, sithi 50 ohms noma 75 ohms, kufanele kuhambisane nomthombo wesignali nomthwalo. Ngaleyo ndlela, uthola ukudluliswa kwesignali okungcono kakhulu futhi unciphise ukubonakaliswa. I-impedance engafani idala amagagasi amile endleleni. Lokho kungabangela amaphutha ezilinganisweni. Bangase balimaze imishini.
(II) Ukusatshalaliswa Kwesiginali kanye Nokuguqulwa
T{{0}Isixhumi. Ixhuma umthombo wesignali kumadivayisi amaningana. Thatha-isixhumi esihlukanisa isignali izingcezu ezimbili zamagiya. Abantu bayisebenzisela ukunweba imigqa ye-coax noma ukushintsha ukuxhumana.
I-Bias T-Isixhumi. Lona uxuba amandla e-DC namasignali e-RF. Iphakela i-DC kumadivayisi-akude anjengama-amp{4}}omsindo ophansi kuma-antenna. Ngaso sonke isikhathi, igcina isignali ye-RF iphephile.
I-DC Blocker. Imisa amasignali e-DC ukuthi angadluli kodwa ivumela i-RF idlule. Lokho kuvikela izingxenye ze-RF ezithambile ezindabeni ze-DC.
(III) Ukuxhuma kanye Nokwandiswa
Ungakwazi ukwelula ama-coaxial cable agijima ngalawa ma-adaptha. Izinhlobo zemigqomo ziwenza kahle lowo msebenzi. Baphinde bajoyine izitayela zokuxhuma ezahlukahlukene njenge-SMA noma i-BNC noma-uhlobo oluthi N. Lokho kuvumela izisetshenziswa ezihlukene ukuthi zikhulume zodwa.
(IV) Ukuvikelwa kanye Nokuhlukaniswa
Ama-adaptha avikela izimbobo zedivayisi emsebenzini wokuhlola. Banciphisa ukuguga futhi basize amagiya ahlale isikhathi eside.
Ukuzihlukanisa nakho kuyasiza. Ama-DC blockers asebenzisa ama-capacitor ukuvimba amasignali e-DC. Bagcina izisetshenziswa ze-RF zingabi yingozi.
III. Izicelo zama-Coaxial Adapter
Lawa ma-adaptha abonakala yonke indawo ezinhlelweni zokuxhumana nasekusetheni irada. Zilingana nezixhumanisi zesathelayithi nezinto zokuhlola nazo. Noma yini edinga izibopho ze-RF ezinembile iyazisebenzisa. Kuma-radio comms neziteshi zamaselula, izixhumi ze-FME ziphatha izixhumanisi eziqinile ze-RF.
I-Millimeter{0}}amasistimu amaza ancike kuzixhumi ezingu-2.92mm. Lawo asekela amafrikhwensi afika ku-40 GHz.
IV. Umgomo Wokusebenza wama-Coaxial Adapter
Ama-adaptha angama-coaxial asebenza ezintweni eziyisisekelo zokudluliswa kwekhebula. Amasignali ahamba nge-conductor yangaphakathi. Engaphandle ivimba umsindo wangaphandle. Ngaphakathi kwe-adaptha, ama-capacitor noma ama-inductors aphatha ukusatshalaliswa noma ukuhlukaniswa noma ukufanisa.
V. Izinyathelo Zokuqaphela Ngokusebenzisa I-Coaxial Adapter
Izidingo zokufaka
Qinisekisa ukuthi izixhumi ziyaqina ngesikhathi sokusetha. Ukulingana okuxekethile noma abathintwayo ababi kuholela ekwehleni kwesignali.
Amandla Esignali
Khetha i-adaptha efana namandla esiginali yakho nebhendi yefrikhwensi. Uma kungenjalo, uba buthakathaka noma uphazamise isignali.
Izici Zemvelo
Cabanga ngendawo ekuzungezile njengokushisa noma umswakama noma ukuzamazama. Khetha imodeli ephatha lezo.
Isondlo Nokunakekela
Hlola futhi usule izixhumi ngezikhathi ezithile. Lokho kuvimbela ukugqwala noma ukungcola ukuthi kungalimazi ukuthi kusebenza kanjani.
Ekugcineni, ama-adaptha ama-coaxial abaluleke kakhulu kuma-comms wanamuhla kanye ne-electronics. Izindima zabo eziningi kanye nokusetshenziswa okubanzi kuziphendulela{1}}ezinezingxenye.
