RF Dummy Imithwalo
I-RF dummy load iyisisetshenziswa se-elekthronikhi esiklanyelwe ukumunca amandla efrikhwensi yomsakazo (RF) futhi siyiguqule ibe ukushisa. Isetshenziselwa ukulingisa umthwalo kusidlulisi noma isekethe ye-RF lapho kuhlolwa noma kushunwa uhlelo, ngaphandle kokudlulisa noma yiziphi izimpawu ze-RF endaweni ezungezile.
Umthwalo we-RF dummy uqukethe into ephikisayo edizayinelwe ukufanisa ukuthinta kwesistimu ye-RF ehlolwayo. Isici esiphikisayo ngokuvamile senziwe ngenxeba lentambo engaguquki ikhoyili noma into yobumba enokumelana okuphezulu. Umthwalo ube usuvalwa kusinki wokushisa ukuze kukhishwe amandla akhiqizwa lapho amandla e-RF emuncwa.
Amanye amagama afanayo we-RF dummy load afaka:
- Umthwalo we-RF
- Dummy load
- Impedance umthwalo
- Ukuqedwa kwe-RF
- I-resistor yokulayisha
- I-coaxial terminator
- Umthwalo wokuhlola we-RF
- Isinqamuli sefrikhwensi yomsakazo
- I-absorber ye-RF
- Isibambisi esignali
I-RF dummy loads iyithuluzi elibalulekile embonini yezokusakaza ngoba ivumela abasakazi ukuthi bahlole futhi bashune amathuluzi abo ngaphandle kokukhipha amasignali e-RF angafunwa. Lapho okokusebenza kokudlulisa kuhlolwa, kubalulekile ukuqinisekisa ukuthi isignali edluliswayo idluliselwa kuphela kwabemukeli abahlosiwe futhi hhayi ngaphandle endaweni lapho ingabangela ukuphazamiseka kwamanye amasignali omsakazo.
Lapho i-transmitter noma isekethe ye-RF ihlolwa ngomthwalo we-RF dummy, umthwalo ulingisa i-impedance ezokwethulwa uthi noma ezinye izingxenye ze-RF ezixhunywe ohlelweni. Ngokwenza kanjalo, uhlelo lungahlolwa futhi lulungiswe ngaphandle kokukhipha noma yimaphi amandla. Lokhu kubaluleke kakhulu uma usebenza nezinhlelo zamandla aphezulu, lapho ngisho nenani elincane lokukhishwa kwamandla kungaba yingozi.
Ekusakazweni, imithwalo yekhwalithi ephezulu ye-RF dummy ibaluleke kakhulu ngoba amasiginali okusakaza adluliselwa kumazinga aphezulu wamandla. I-RF dummy load yekhwalithi ephezulu ingamunca ngempumelelo amandla akhiqizwa amasiginali e-RF enamandla amakhulu, esiza ukuvimbela isistimu ekushiseni ngokweqile noma ekulimazeni izingxenye.
Ukusebenzisa i-RF dummy load yekhwalithi ephansi kungabangela ukubonakaliswa kwesignali, okuholela esignali engazinzile noma ehlanekezelwe. Lokhu kungaholela ekulahlekeni kwedatha, amasignali awehlisiwe, noma ezinye izinkinga. Esiteshini sokusakaza esiphrofeshinali, ukugcina ubuqotho besignali kubalulekile ekuqinisekiseni ukuthi ukusakaza kuyemukelwa futhi kuqondwa izethameli ezihlosiwe.
Sekukonke, imithwalo ye-RF dummy iyingxenye ebalulekile yokuhlolwa kwe-RF nokulinganisa, ihlinzeka ngendlela ephephile nephumelelayo yokulingisa umthwalo we-RF kusidluliseli noma isekethe, umthwalo wezinga eliphezulu we-RF dummy ubalulekile eziteshini zokusakaza ezichwepheshile ngoba usiza ukuqinisekisa ukudluliswa okunembile kwamasignali e-RF futhi kuvikela okokusebenza ekulimaleni.
