I-Waveguide Fixed Attenuators RF Microwave Millimeter Wave mm wave
I-Waveguide Fixed Attenuators sisixhobo esingasetyenziswayo esisetyenziswa kakhulu kwicandelo lobuchwepheshe be-microwave.
Yenzelwe ukunciphisa imiqondiso ye-microwave edluliselwa kwii-waveguides ngomlinganiselo omiselweyo. Umzekelo, xa isignali ye-microwave idlula kwi-waveguide fixed attenuator, inxalenye yamandla iyafunxwa okanye ilahleke ngenye indlela, ngaloo ndlela kunciphisa amandla esignali yokuphuma.
I-Waveguide luhlobo lwesakhiwo se-waveguide esisetyenziselwa ukuhambisa ii-microwave. I-waveguide fixed attenuator isekelwe kwisakhiwo se-waveguide kwaye ifezekisa ubungakanani bokunciphisa obuzinzileyo ngokusebenzisa izinto ezikhethekileyo okanye uyilo lwesakhiwo. Idla ngokusebenzisa izixhobo ezikhuselayo okanye izakhiwo ezikhethekileyo ze-electromagnetic ukufunxa amandla e-microwave.
Injongo:
1. Ukuncitshiswa kweSignali: Ii-RF attenuators zisetyenziselwa ukunciphisa ngokuchanekileyo amandla e-RF kunye ne-microwave signals ukukhusela izixhobo zokwamkela ezibuthathaka kunye namanqanaba esignali yokulawula.
2. Ukulinganisa Amandla: Izixhobo zokunciphisa amandla kwi-microwave zingasetyenziselwa ukulinganisa inqanaba lamandla enkqubo, ngaloo ndlela zinciphisa ukubonakaliswa kwamaza amileyo kwaye ziphucule ukusebenza kwenkqubo.
3. Ukulinganisa Inkqubo: Ii-Millimeter wave attenuators zisetyenziselwa ukulinganisa nokuvavanya iinkqubo ze-RF kunye ne-microwave ukuqinisekisa ukusebenza okuzinzileyo kwenkqubo kumanqanaba ahlukeneyo ombane.
Isicelo:

2. Unxibelelwano lweSathelayithi: Kwiinkqubo zonxibelelwano lwesathelayithi, ii-attenuator ezizinzileyo zisetyenziselwa ukulungisa amandla esignali ukuqinisekisa ukuthembeka nokuzinza kwekhonkco lonxibelelwano. Zingasetyenziselwa ukuhanjiswa kwesignali phakathi kwezikhululo zomhlaba kunye neesathelayithi.
3. Unxibelelwano lweMicrowave: Kwiinkqubo zonxibelelwano lweMicrowave, ii-attenuators zeMicrowave zisetyenziselwa ukulungisa nokulawula amandla esignali ukuphucula ukusebenza kunye nokuthembeka kwamakhonkco onxibelelwano.
4. Uvavanyo kunye nokulinganisa: Kwiinkqubo zovavanyo kunye nokulinganisa ze-RF kunye ne-microwave, ii-millimeter wave attenuators zisetyenziselwa ukulawula ngokuchanekileyo amandla esignali kwiimvavanyo ezahlukeneyo kunye nokulinganisa. Oku kubalulekile ukuqinisekisa ukusebenza kwezixhobo kunye neenkqubo zakho.
5. Unomathotholo noMabonakude: Kwiinkqubo zikanomathotholo noomabonakude, ii-mm wave attenuators zisetyenziselwa ukulungisa amandla esignali nokuphucula umgangatho wesignali kunye nokugubungela kwayo. Oku kunceda ekuboneleleni ngemiqondiso yesandi nevidiyo ecacileyo.
6. Uphando lwezeSayensi: Kwiiprojekthi zophando lwezeSayensi, ii-waveguide fixed attenuators zisetyenziselwa ukulawula nokulawula amandla e-RF kunye nesignali ye-microwave kwiimvavanyo. Ezi zifundo zinokubandakanya i-astronomy, i-physics, kunye nezinye iinkalo.
I-Qualwaveibonelela nge-VSWR ephantsi kunye nokuqina okuphezulu kokunciphisa ukusuka kwi-3.94 ukuya kwi-500GHz. Uluhlu lokunciphisa yi-0 ~ 40dB.
