Waveguide Fixed Attenuators RF Microwave Millimeter Wave mm wave
I-Waveguide Fixed Attenuators sisixhobo esisetyenziswayo esisetyenziswa kakhulu kwi-teknoloji ye-microwave.
Yenzelwe ukuthomalalisa imiqondiso ye-microwave ehanjiswa kwii-waveguides ngokomlinganiselo omiselweyo. Umzekelo, xa isignali ye-microwave idlula kwi-attenuator esisigxina ye-waveguide, inxalenye yamandla iyafunxwa okanye ilahleke ngenye indlela, ngaloo ndlela inciphisa amandla ophawu oluphumayo.
I-Waveguide luhlobo lwesakhiwo se-waveguide esisetyenziselwa ukuhambisa ii-microwaves. I-attenuator esisigxina ye-waveguide isekwe kwisakhiwo se-waveguide kwaye ifezekisa isixa esisisigxina sokunciphisa ngemathiriyeli ekhethekileyo okanye uyilo lolwakhiwo. Ihlala isebenzisa izixhobo ezixhathisayo okanye izinto ezikhethekileyo ze-electromagnetic ukufunxa amandla e-microwave.
Injongo:
1. Ukujongwa koMqondiso: Izithinteli zeRF zisetyenziselwa ukuthomalalisa ngokuthe ngqo amandla e-RF kunye neesignali zemicrowave ukukhusela izixhobo zokwamkela ezinovakalelo kunye nokulawula amanqanaba omqondiso.
2. Ukulinganisa Amandla: I-Microwave attenuators ingasetyenziselwa ukufanisa umgangatho wamandla wenkqubo, ngaloo ndlela inciphisa izibonakaliso kunye namaza okuma kunye nokuphucula ukusebenza kwenkqubo.
3. Ulungelelwaniso lweNkqubo: Izithinteli zamaza eMillimeter zisetyenziselwa ukulinganisa nokuvavanya iinkqubo zeRF kunye ne-microwave ukuqinisekisa ukusebenza okuzinzile kwenkqubo kumanqanaba ombane ahlukeneyo.
Isicelo:
1. Inkqubo yeRadar: Kwiinkqubo ze-radar, i-attenuators ye-waveguide isetyenziselwa ukulungelelanisa nokulawula ubuninzi beempawu ezidlulisiweyo kunye nezifunyenweyo. Oku kunceda ukuphucula amandla okubona kunye nokuchaneka kweenkqubo ze-radar.
2. Unxibelelwano lweSatellite: Kwiinkqubo zonxibelelwano lwesathelayithi, i-attenuators esisigxina isetyenziselwa ukulungelelanisa amandla omqondiso ukuqinisekisa ukuthembeka kunye nokuzinza kwekhonkco lonxibelelwano. Zingasetyenziselwa ukuhanjiswa komqondiso phakathi kwezikhululo zomhlaba kunye neesathelayithi.
3. Unxibelelwano lweMicrowave: Kwiinkqubo zonxibelelwano kwi-microwave, i-microwave attenuators isetyenziselwa ukulungelelanisa nokulawula amandla omqondiso wokuphucula ukusebenza kunye nokuthembeka kwamakhonkco onxibelelwano.
4. Uvavanyo kunye nomlinganiselo: Kwi-RF kunye ne-microwave yovavanyo kunye neenkqubo zokulinganisa, i-millimeter wave attenuators zisetyenziselwa ukulawula ngokuchanekileyo amandla omqondiso kwiimvavanyo ezahlukeneyo kunye nokulinganisa. Oku kubalulekile ukuqinisekisa ukusebenza kwezixhobo zakho kunye neenkqubo.
5. Irediyo kunye nomabonwakude: Kwiinkqubo zerediyo kunye nomabonwakude, ii-mm wave attenuators zisetyenziselwa ukulungelelanisa amandla omqondiso kunye nokuphucula umgangatho wesignali kunye nokugubungela. Oku kunceda ukubonelela ngesandi esicacileyo kunye neempawu zevidiyo.
6. UPhando lwezeNzululwazi: Kwiiprojekthi zophando lwezenzululwazi, i-waveguide fixed attenuators zisetyenziselwa ukulawula nokulawula iRF kunye namandla omqondiso we-microwave kwimifuniselo. Ezi zifundo zinokubandakanya i-astronomy, i-physics, kunye nezinye iinkalo.
QualwaveIbonelela nge-VSWR ephantsi kunye nokunyuka okuphezulu kokuthomalalisa ukusuka kwi-3.94 ukuya kwi-500GHz. Uluhlu lokuthomalalisa yi-0~40dB.
