VHF Coupers

I-VHF hybrid coupler iyithuluzi lokungenzi lutho elihlanganisa noma elihlukanisa amasignali ebangeni le-VHF (imvamisa ephezulu kakhulu). Ivamise ukusetshenziswa ezinhlelweni ze-RF (ifrikhwensi yomsakazo) yokuhlukanisa amasignali, ukuhlanganisa amasignali, kanye nokumatanisa kwe-antenna. Izinhlelo zokusebenza ezivame kakhulu ze-VHF hybrid coupler zifaka phakathi ukuhlanganisa/ukuhlukanisa i-antenna, ukusatshalaliswa kwesignali, kanye nokufanisa i-impedance. Ekuhlanganiseni kwe-antenna/ukuhlukanisa, i-hybrid coupler isetshenziselwa ukuhlanganisa noma ukuhlukanisa amasignali phakathi kwezimpondo ezimbili, okuvumela izimpondo eziningi ukuthi zisetshenziswe ohlelweni olufanayo. Ekusabalaliseni isignali, i-hybrid coupler isetshenziselwa ukuhlukanisa isignali ibe yimiphumela eminingi, okuvumela isignali ukuthi ihanjiswe ezindaweni ezihlukene. Ekufanisweni kwe-impedance, i-hybrid coupler isetshenziselwa ukufanisa ukuvinjelwa kwezingxenye ezimbili ukuze kwehliswe ukubonakaliswa nokuthuthukisa ikhwalithi yesignali.

Iyini i-VHF hybrid coupler, futhi iyini igama elifanayo layo?
I-VHF hybrid coupler iyingxenye kagesi esetshenziselwa ukuhlanganisa noma ukuhlukanisa amasignali kusekethe ye-VHF (imvamisa ephezulu kakhulu). Igama layo elifanayo liyi-diplexer.
Uyisebenzisa kanjani i-VHF hybrid coupler ukusakaza?
izinyathelo:
1. Beka i-VHF hybrid coupler ekuphumeni komthumeli wesiteshi sokusakaza.
2. Xhuma imbobo ye-antenna ye-VHF hybrid coupler kokuthi uthi.
3. Xhuma imbobo yokudlulisela ye-VHF hybrid coupler kusidlulisi.
4. Lungisa izinga lamandla esidluliseli ezingeni lamandla olifunayo.

Isebenza kanjani i-VHF hybrid coupler?
I-VHF hybrid coupler isetshenziswa esiteshini sokusakaza ukuhlukanisa isiginali isuka kothi olulodwa ibe yimiphumela emibili ehlukene, okuvumela uthi olulodwa ukuphakela ama-transmitters amabili. Isebenza ngokuhlanganisa amasignali asuka ezintini abe isignali eyodwa bese ihlukanisa isignali ehlanganisiwe ibe amasignali amabili, ngalinye linamandla alinganayo. Lokhu kuvumela ama-transmitters amabili ukuthi asebenze ngesikhathi esisodwa ngaphandle kokuphazamisana.
Kungani i-VHF hybrid coupler ibalulekile esiteshini somsakazo?
I-VHF hybrid coupler iyingxenye ebalulekile yesiteshi sokusakaza ngoba ivumela ukudluliselwa nokwamukela amasignali ngebhendi yefrikhwensi ye-VHF. Ngokuhlanganisa i-transmitter nomamukeli ndawonye, ​​i-coupler eyi-hybrid iqinisekisa ukuthi isignali edlulisiwe yamukelwa njengoba kuhlosiwe. Lokhu kubaluleke kakhulu eziteshini ezisakaza okuqukethwe okulalelwayo noma kwevidiyo, njengoba ukudluliselwa okucacile kwesiginali kubalulekile ukuze kudlalwa kahle. Ngaphandle kwe-hybrid coupler, iziteshi ngeke zikwazi ukusebenzisa amaza e-VHF futhi zizokhawulelwa ekusebenziseni amaza ngaphandle kwebhendi ye-VHF.
Zingaki izinhlobo ze-VHF hybrid couplers ezikhona futhi yimuphi umehluko phakathi kwazo?
Kunezinhlobo ezintathu ezihlukene ze-VHF hybrid couplers: ama-couplers aqondisayo, ama-hybrid couplers, nama-power dividers. Ama-coupler aqondisayo asetshenziselwa ukukala amazinga wamandla oya phambili nakahlehla ukusuka ku-antenna eyodwa, kuyilapho ama-hybrid coupler asetshenziselwa ukuhlanganisa amasignali amabili ukuze kutholwe amandla amakhulu. Izihlukanisi zamandla zisetshenziselwa ukuhlukanisa isignali eyodwa ibe amandla alinganayo amabili noma ngaphezulu alinganayo. Umehluko omkhulu phakathi kwezinhlobo ezahlukene ububanzi befrikhwensi namandla okubamba amandla.
Ungayikhetha kanjani i-VHF hybrid coupler engcono kakhulu?
Lapho ukhetha i-coupler eyi-hybrid ye-VHF engcono kakhulu yesiteshi sokusakaza, kubalulekile ukucabangela izici ezilandelayo: ukuphuma kwamandla, ukuqondisa, ukulahlekelwa kokufaka, ukuhlukaniswa, isibalo somsindo, nokulahlekelwa kokubuyisela. Ukwengeza, kubalulekile ukucabangela ubukhulu nesisindo sedivayisi kanye nentengo. Ukucwaninga ngemikhiqizo ehlukene namamodeli ukuze uqhathanise lezi zici kungakusiza ukuthi uthole inketho engcono kakhulu yezidingo zakho. Qiniseka ukuthi ufunda izibuyekezo futhi uxhumane nesevisi yamakhasimende ukuze uthole ulwazi olwengeziwe ngaphambi kokufaka i-oda lakho lokugcina.
