Njengenxalenye ephambili kwiinkqubo zovavanyo lwe-microwave kunye nonxibelelwano, i-Programmable Attenuator ilungisa ngokuchanekileyo i-amplitude yesignali ye-microwave ngokulawula inethiwekhi ye-resistor echanekileyo yangaphakathi ngemiyalelo yedijithali. Ixabiso layo eliphambili lixhomekeke ekutshintsheni ii-attenuator zemveli ezenziwe ngesandla, zibonelela ngolawulo lwesignali oluzenzekelayo olunesisombululo esiphezulu, oluchanekileyo ngaphakathi kwebhendi yefrikhwensi ebanzi ukuhlangabezana neemfuno zeenkqubo ze-elektroniki zanamhlanje zokusebenza kude kunye nokuphendula ngokukhawuleza. Oku kulandelayo yintshayelelo eneenkcukacha ezivela kwiinkalo ezimbini: iimpawu zayo eziphambili zemveliso kunye neendawo eziphambili zesicelo.

Iimpawu:

1. Ukuchaneka okuphezulu kunye nenyathelo elincinci: Le mveliso inenyathelo elincinci le-0.25dB, evumela uhlengahlengiso oluncinci kakhulu lwe-amplitude yesignali. Uluhlu olupheleleyo lokuncitshiswa lufikelela kwi-63.75dB, lugubungela uluhlu olubanzi oluguquguqukayo ukusuka kwizibonakaliso ezibuthathaka ukuya kwezomeleleyo. Ukuchaneka kwayo okuqhelekileyo kokuncitshiswa kunokufikelela kwi-±2dB, kuqinisekisa ukuchaneka kunye nokuphindaphindwa phantsi kwezicwangciso ezahlukeneyo.
2. Ugutyungelwa kwefrikhwensi ye-Ultra-wideband: Ugutyungelwa kwefrikhwensi yokusebenza luqala kwi-0.02GHz ukuya kwi-18GHz, lugubungela phantse zonke iibhendi zonxibelelwano ezibalulekileyo kunye ne-radar. Olu gutyungelwa kwefrikhwensi ebanzi luyivumela ukuba ikwazi ukuphatha imiqondiso kwiibhendi ezahlukeneyo kwiqonga elinye, nto leyo esusa isidingo sokutshintsha izixhobo ezininzi.
3. Ukulahleka okuphantsi kokufakwa kunye nokuhambelana okuhle: Ukulahleka kwayo okuphezulu kokufakwa kulawulwa ngaphakathi kwe-8dB, kunciphisa ukusetyenziswa kwamandla esignali yokuqala. Okwangoku, umlinganiselo ophezulu wamaza okuma kwevolthi kwiiports zayo zokufaka kunye neziphumo yi-2.0, ukuqinisekisa ukuhambelana okuhle kwe-impedance neenkqubo ze-50Ω, kunciphisa ngempumelelo ukubonakaliswa kwesignali kunye nokuqinisekisa ukuthembeka kokudluliselwa kwesignali.
4. Ulawulo olunokucwangciswa oluthembekileyo kunye noyilo lwesakhiwo: Le mveliso ixhasa ulawulo olukude ngokusebenzisa ii-interfaces eziqhelekileyo, iququzelela ukuhlanganiswa kwiinkqubo zovavanyo ezizenzekelayo. Ezinye uyilo zikwaqwalasela ukuguquguquka kwendalo, zigcina ukusebenza okuzinzileyo kumanqanaba obushushu abanzi.

Izicelo:

1. Uvavanyo lwenkqubo yonxibelelwano: Kwi-R&D kunye nokuveliswa kwezikhululo zesiseko ze-5G, izikhululo zomhlaba zonxibelelwano lwesathelayithi, kunye neenkqubo zeradar, esi sithinteli sisetyenziswa kakhulu ukulinganisa ukulahleka kokudluliselwa kwesignali esibhakabhakeni.
2. Iinkqubo zovavanyo ezizenzekelayo: Njengenxalenye ephambili yokulungisa isignali kwiinkqubo ze-ATE, inokulawula ngokuchanekileyo igalelo lenqanaba lesignali kwizixhobo ezifana nabahlalutyi be-spectrum, iijenereyitha zesignali, okanye iimitha zamandla. Oku akuthinteli nje kuphela umonakalo kwizixhobo zovavanyo ezibizayo ngenxa yamandla agqithisileyo esignali kodwa kuqinisekisa ukuba imilinganiselo ithathwa kwi-amplitude yesignali efanelekileyo, ngaloo ndlela iphucula uluhlu oluguquguqukayo kunye nokuchaneka kokulinganisa kwenkqubo yonke yovavanyo.
3. Uvavanyo lwecandelo kunye nomgca wemveliso: Kuvavanyo lokuvelisa ngobuninzi be-RF kunye ne-microwave components, esi sixhobo sisetyenziselwa ukwenza ngokukhawuleza nangokuchanekileyo ukuqinisekiswa kokusebenza kunye nokuhlolwa kokusebenza. Ngokutshintsha ngokuzenzekelayo amandla esignali yokufaka, ijika lempendulo yesixhobo esivavanywa phantsi kweemeko ezahlukeneyo zesignali linokuchazwa ngokufanelekileyo.
4. Uphando kunye novavanyo lwemfundo: Kwiilabhoratri ze-microwave zeeyunivesithi kunye namaziko ophando, yinxalenye ebalulekileyo yokwakha amaqonga ovavanyo lokulinganisa itshaneli kunye nophando lokusasazwa kwamaza, ukunceda abaphandi balinganise iindawo ezintsonkothileyo ze-electromagnetic kunye nokuqinisekisa iimodeli kunye noyilo lwethiyori.

I-Qualwave Inc. ibonelela nge-broadband, uluhlu oluphezulu oluguquguqukayoizithinteli ezicwangcisiweyongamaza afikelela kwi-40GHz. Inyathelo linokufikelela kwi-0.5dB, kwaye uluhlu lokuncitshiswa lunokufikelela kwi-80dB okanye ngaphezulu. Eli nqaku lizisa i-attenuator ecwangcisiweyo ye-0.02~18GHz enoluhlu lokuncitshiswa lwe-0~63.75dB kunye nenyathelo le-0.25dB.
