Isihlanganisi se-L-band sisetshenziselwa ini?

Isihlanganisi se-L-band iyidivayisi esetshenziselwa ukuhlanganisa amasignali amaningi asuka emithonjeni ehlukene, ngokuvamile ebangeni lefrikhwensi ye-L, ibe okokukhiphayo okukodwa. Izinhlelo zokusebenza ezijwayelekile zesihlanganisi se-L-band zihlanganisa ukuhlanganisa amasiginali amaningi wesathelayithi kumabonakude wesathelayithi, ukuhlanganisa amasiginali amaningi angenazintambo kumanethiwekhi amaselula, nokuhlanganisa amasignali amaningi omsakazo eziteshi zomsakazo ezisakazwayo.

Usisebenzisa kanjani isihlanganisi se-L-band ekusakazeni?

Izinyathelo zokusebenzisa kahle isihlanganisi se-L-band esiteshini sokusakaza:
1. Xhuma ukuphela kokufaka kwesihlanganisi kokuphumayo komthumeli.
2. Xhuma ukuphela kwesihlanganisi kokuthi uthi.
3. Xhuma ukunikezwa kwamandla kusihlanganisi.
4. Lungisa ukulawula kwenzuzo yesihlanganisi ukuze usethe ileveli yesiginali oyifunayo.

Ukuze ugweme izinkinga lapho usebenzisa isihlanganisi se-L-band esiteshini sokusakaza:
1. Qiniseka ukuthi uthi luvunwe ngendlela efanele amaza asetshenziswayo.
2. Qinisekisa ukuthi ugesi osetshenziswayo uhambisana nesihlanganisi.
3. Hlola kabili ukuze uqiniseke ukuthi konke ukuxhumana kuphephile futhi kunqanyulwe ngendlela efanele.
4. Gada amazinga esignali njalo ukuze uqinisekise ukuthi azikho izinguquko ezingalindelekile noma ukuhlanekezela.

Sisebenza kanjani isihlanganisi se-L-band?

Isihlanganisi se-L-band iyisisetshenziswa sikagesi esisetshenziselwa ukuhlanganisa amasignali omsakazo amaningi abe okukhiphayo okukodwa esiteshini sokusakaza. Okukhiphayo kuvame ukuthunyelwa kokuthi i-antenna ukuze isakazwe. Isihlanganisi se-L-band sisebenzisa isikhulisi somsindo ophansi (LNA) ukuze sikhulise isignali ehlanganisiwe ngaphambi kokuyithumela ku-antenna. I-LNA yakhelwe ukunciphisa umsindo, ukuthuthukisa isilinganiso sesignali-kuya-nomsindo futhi ikhuphule amandla esignali isiyonke. Le nhlanganisela yezinto ivumela ukudluliselwa ngesikhathi esisodwa kwamasignali amaningi ngaphandle kokuphazanyiswa noma ukulahlekelwa ikhwalithi yesignali.

Zingaki izinhlobo zezihlanganisi ze-L-band ezikhona futhi yimuphi umehluko phakathi kwazo?

Kunezinhlobo ezintathu zezihlanganisi ze-L-band: izihlanganisi ezihlukanisayo, izihlanganisi ze-bandpass, nama-diplexer. Izihlanganisi ze-Splitter zihlukanisa isignali zibe izindlela ezimbili ezihlukene futhi zivumele ukuthi isignali ihlanganiswe nenye isignali. Izihlanganisi ze-bandpass zihlanganisa isignali kumafrikhwensi athile, okuvumela ukuthi isiginali ihlungwe kububanzi obuthile bokuvama. Ama-Diplexer ahlanganisa amasignali amabili ahlukene kumafrikhwensi ahlukene futhi awavumele ukuba adlule echwebeni elifanayo. Umehluko phakathi kohlobo ngalunye lwesihlanganisi usendleleni ezihlanganisa ngayo amasignali namaza eziklanyelwe ukusebenza kuwo.

Ukhetha kanjani isihlanganisi esihle kakhulu se-L-band?

Lapho ukhetha isihlanganisi se-L-band esiteshini sokusakaza, kufanele ucabangele izici ezifana nebanga lefrikhwensi, ukulahlekelwa kokufaka, ukuhlukaniswa, ukuphatha amandla nokulahlekelwa kokubuyisela. Ukwengeza, kufanele ufunde ukubuyekezwa okuku-inthanethi futhi uqhathanise izici zamamodeli ahlukene ukuze uqinisekise ukuthi umkhiqizo uhlangabezana nezidingo zesiteshi sakho. Okokugcina, kufanele uthintane nochwepheshe bezobuchwepheshe ukuze uqinisekise ukuthi ukhetha umkhiqizo ongcono kakhulu wesiteshi sakho sokusakaza.

Usixhuma kanjani kahle isihlanganisi se-L-band ohlelweni lokusakaza?

Ukuze uxhume kahle isihlanganisi se-L-band esiteshini sokusakaza, uzodinga ukusebenzisa amakhebuli angama-coaxial ukuze uxhume izimbobo zokufaka zesihlanganisi kumachweba okukhiphayo e-RF ezithumeli zesiteshi sakho sokusakaza. Bese, xhuma intambo ye-coaxial embobeni yokukhiphayo yesihlanganisi bese uyixhuma embobeni yokufaka yothi lwakho. Okokugcina, qiniseka ukuthi konke ukuxhumana kuvikelekile nokuthi amazinga wamandla ezithumeli afanelana namazinga wamandla esihlanganisi.

Yiziphi izinto ezisetshenziswayo ezihlobene nesihlanganisi se-L-band?

Imishini ehlobene nesihlanganisi se-L-band esiteshini sokusakaza ihlanganisa izihlukanisi ze-L-band, ama-amplifiers anenzuzo ephezulu, izihlukanisi zamandla, intambo eyi-coaxial, nama-attenuators.

Yiziphi izici ezibaluleke kakhulu zomzimba neze-RF zesihlanganisi se-L-band?

Izicaciso ezibaluleke kakhulu zomzimba neze-RF zesihlanganisi se-L-band zifaka:
- Ibanga Lemvamisa: 960 MHz kuya ku-1710 MHz
- Inani Lokufaka/Okukhiphayo: 4 noma ngaphezulu
- Ukulahlekelwa Kokufaka: ≤0.5 dB
- Ukuzihlukanisa: ≥30 dB
- I-VSWR: ≤1.5:1
- Ukubamba Amandla: ≥200 W
- Izixhumi: Uhlobo N noma Thayipha i-SMA

Usigcina kanjani kahle isihlanganisi se-L-band njengonjiniyela?

1. Hlola isihlanganisi se-L-band ukuze uthole noma yimuphi umonakalo noma izimpawu zokuguga.

2. Hlola konke ukuxhumeka kusihlanganisi ukuze uqinisekise ukuxhuma okuphephile kukagesi.

3. Hlola amazinga amandla esihlanganisi ukuze uqiniseke ukuthi singaphakathi kwezicaciso ezidingekayo.

4. Hlanza isihlanganisi nezingxenye zaso ukuze uqiniseke ukuthi alukho uthuli noma imfucumfucu.

5. Hlola imvamisa yesihlanganisi ukuze uqinisekise ukuthi izinzile futhi ilungile.

6. Hlola ukusebenza kwesihlanganisi ukuze uqiniseke ukuthi sinikeza izinga elidingekayo lekhwalithi yesiginali.

7. Yenza noma yikuphi ukulungisa okudingekayo noma ukulungisa kusihlanganisi se-L-band.

8. Qopha yonke imisebenzi yokulungisa futhi ugcine imininingwane ukuze isetshenziswe esikhathini esizayo.

Usilungisa kanjani isihlanganisi se-L-band uma singasebenzi?

Ukuze ulungise isihlanganisi se-L-band, qala uhlole isihlanganisi noma yiziphi izimpawu ezisobala zomonakalo. Hlola ukuze uqiniseke ukuthi zonke izintambo zixhumeke kahle nokuthi akukho ukuxhumana okuxekethile. Hlola uxhumo lwamandla futhi uqiniseke ukuthi luxhumeke ngokuphephile. Uma noma yiziphi izingxenye zibonakala zilimele, kufanele zishintshwe.

Uma isihlanganisi sihluleka ukusebenza, imbangela yokwehluleka kufanele ikhonjwe kuqala. Uma ukwehluleka kungenxa yengxenye ephukile, ingxenye ingashintshwa. Ngaphambi kokushintsha ingxenye, kubalulekile ukuqinisekisa ukuthi ingxenye eshintshwayo iyahambisana nesihlanganisi. Ngemva kokufakwa kwengxenye entsha, isihlanganisi kufanele sihlolwe ukuze kuqinisekwe ukuthi sisebenza kahle.

Ukhetha kanjani ukupakishwa okulungile kwesihlanganisi se-L-band?

Uma ukhetha ukupakisha okulungile kwesihlanganisi se-L-band, kubalulekile ukwenza isiqiniseko sokuthi ivikelekile kunoma yikuphi ukushaqeka, ukudlidliza, noma izinguquko zezinga lokushisa ezingalimaza idivayisi. Ibhokisi lokupakisha eliqinile, elivikela umswakama kufanele lisetshenziselwe ukuvikela isihlanganisi kunoma yimuphi umonakalo ongaba khona ngesikhathi sokuthutha. Qiniseka ukuthi ufaka izinto zokupakisha ezifana nama-cushions egwebu nokugoqwa kwebhamuza ukuze uthole ukuvikelwa okwengeziwe kwedivayisi. Ukwengeza, kubalulekile ukulebula iphakheji ngokucacile futhi uqinisekise ukuthi livalwe kahle futhi livikelekile. Lokhu kuzoqinisekisa ukuthi isihlanganisi sifika ngokuphepha futhi sikhululekile kunoma yimuphi umonakalo.

Iyiphi impahla esetshenziselwa ukufakwa kwe-casing yesihlanganisi se-L-band?

I-casing yesihlanganisi se-L-band ngokuvamile yenziwa ngensimbi, njenge-aluminium noma insimbi engagqwali. Lezi zinto zingathinta ukusebenza kwesihlanganisi ngenxa yesimo sazo sokuqhuba, esingaholela ekwehleni kokusebenza kahle kokudluliswa kwamandla noma ukwanda kokulahlekelwa kwesignali. Ukwengeza, ama-casings ensimbi nawo angase athintwe ukushintsha kwezinga lokushisa, okungawabangela ukuba ande futhi anciphe, okungase kuthinte ukusebenza kwesihlanganisi.

Siyini isakhiwo esiyisisekelo sesihlanganisi se-L-band?

Isihlanganisi se-L-band ngokuvamile siqukethe izingxenye ezintathu ezinkulu: isihlungi se-low-pass, isihlukanisi samandla, nesihlungi se-high-pass. Isihlungi se-low-pass sinesibopho sokwenqaba amafrikhwensi angaphandle kwebhendi, kuyilapho isihlukanisi samandla sivimbela ukuphazamiseka phakathi kwamasignali okokufaka. Isihlungi se-high-pass sinesibopho sokwenqaba noma yimaphi amasiginali angaphansi kwebhendi yokudlula, futhi sinesibopho sokunquma izimfanelo nokusebenza kwesihlanganisi. Ngaphandle kwanoma yiziphi izakhiwo ezintathu, isihlanganisi besingeke sikwazi ukusebenza kahle.

Ubani okufanele abelwe ukusebenzisa isihlanganisi se-L-band?

Esiteshini sokusakaza, unjiniyela kufanele abelwe ukuphatha isihlanganisi se-L-band. Lo muntu kufanele abe namakhono aqinile ezobuchwepheshe, ukujwayelana nemishini yokusakaza emsakazweni, amakhono okuxazulula izinkinga, kanye nekhono lokusebenza ngokuzimela.
