IsiXhobo soQhagamshelo seDigridi ezingama-90, iFrequency 4 ~ 12GHz, Amandla aPhakathi angama-50W, iSMA yabasetyhini

Isixhobo sokudibanisa esidityaniswe ne-90 degrees sisixhobo esingena kwi-microwave esineeport ezine. Xa isignali ingena kwenye yeeports, isasaza ngokulinganayo amandla esignali kwiiports ezimbini zokukhupha (isiqingatha ngasinye, oko kukuthi -3dB), kwaye kukho umahluko wesigaba se-90 degrees phakathi kwezi signals zimbini zokukhupha. Esinye i-port sisiphelo esizimeleyo, ngokufanelekileyo ngaphandle kokukhupha amandla. Oku kulandelayo kwazisa ngokufutshane iimpawu zayo kunye nokusetyenziswa kwayo:

Ezona mpawu:

1. Ukugubungela ifrikhwensi ye-Ultra-wideband
Ixhasa ukusebenza kwe-ultra-wideband ukusuka kwi-4 ukuya kwi-12 GHz, igubungela ngokugqibeleleyo i-C-band, i-X-band, kunye nenxalenye yezicelo ze-Ku-band. Icandelo elinye linokuthatha indawo yezixhobo ezininzi ze-narrowband, lenze lula uyilo lwenkqubo kwaye linciphise uluhlu lwezinto kunye neendleko.
2. Amandla aphezulu okuphatha
Uyilo oluhle kakhulu lobushushu nolwakhiwo lwenza kube lula ukuphatha amandla ombane afikelela kwi-50W, nto leyo ehlangabezana neemfuno ezifunekayo zonxibelelwano lothumelo olunamandla aphezulu. Inika ukuthembeka okuphezulu kunye nobomi benkonzo ende.
3. Ukudibanisa okuchanekileyo kwe-3dB quadrature
Ibonisa umahluko ochanekileyo wesigaba se-90-degree (i-quadrature) kunye ne-3dB coupling. Ibonisa ibhalansi ye-amplitude egqwesileyo kunye nokulahleka okuphantsi kokufakwa, yahlulahlula ngokufanelekileyo isignali yokufaka ibe ziisignali ezimbini zokukhupha ezine-amplitude efanayo kunye ne-orthogonal phase.
4. Ukwahlulwa okuphezulu kunye nokuhambelana okugqwesileyo kweechweba
Izibuko elizimeleyo liquka umthwalo wangaphakathi ohambelanayo, libonelela ngokwahlukana okuphezulu kwaye linciphisa ngempumelelo i-crosstalk yesignali phakathi kwamazibuko, liqinisekisa uzinzo lwenkqubo. Zonke iizibuko zine-voltage standing wave ratio (VSWR) egqwesileyo kunye nokuhambelana kwezibuko, nto leyo enciphisa ukubonakaliswa kwesignali kakhulu.
5. Ujongano oluqhelekileyo lwabasetyhini be-SMA
Zixhotyiswe nge-SMA female (SMA-F) interfaces, ezihambelana nemigangatho yoshishino. Zibonelela ngonxibelelwano olulula noluthembekileyo, oluvumela ukuhlanganiswa ngokuthe ngqo neentambo ezininzi zamadoda ze-SMA kunye neeadaptha ezikwimarike.
6. Umgangatho oqinileyo womgangatho womkhosi
Yakhiwe ngentsimbi ekhuselweyo ngokupheleleyo, inesakhiwo esomeleleyo, iyakwazi ukumelana nokungcangcazela kunye nefuthe, kwaye ineempawu zokukhusela nge-electromagnetic ezigqwesileyo. Isebenza kakuhle nangona iimeko zokusingqongileyo zinzima.

Izicelo eziqhelekileyo:

1. Iinkqubo zeradar ezicwangcisiweyo ngokwezigaba: Zisebenza njengeyunithi ephambili kwiBeamforming Networks (BFN), zibonelela ngemiqondiso yokuvuselela enobudlelwane besigaba esithile kwizinto ezininzi ze-antenna ukuze kuskenwe ngemitha ye-elektroniki.
2. Iinkqubo ze-amplifier ezinamandla aphezulu: Zisetyenziswa kwiindlela zoyilo ze-amplifier ezilungelelanisiweyo zokusasazwa kwesignali kunye nokudibanisa, ukuphucula amandla okukhupha inkqubo kunye nokuthembeka ngelixa kuphuculwa ukuhambelana kokufaka/ukuphuma.
3. Ukuguqulwa kwesignali kunye nokususwa kwesignali: Isebenza njengomvelisi wesignali ye-quadrature kwiimodulators ze-I/Q kunye needemodulators, nto leyo eyenza ukuba ibe yinxalenye ebalulekileyo kwiinkqubo zonxibelelwano zanamhlanje kunye neenkqubo zokuhambisa i-radar.
4. Iinkqubo zovavanyo kunye nokulinganisa: Zisebenza njengesixhobo sokwahlula amandla ngokuchanekileyo, isixhobo sokudibanisa, okanye isixhobo sokubhekisa kwisigaba kumaqonga ovavanyo lwe-microwave okusasaza isignali, ukudibana, kunye nokulinganisa isigaba.
5. Iinkqubo ze-elektroniki countermeasure (ECM): Zisetyenziselwa ukuvelisa imiqondiso eguquliweyo enzima kunye nokwenza i-signal processing, ukuhlangabezana neemfuno ze-broadband kunye namandla aphezulu eenkqubo zemfazwe ze-elektroniki.

I-Qualwave Inc. ibonelela ngee-broadband kunye nee-90 degrees hybrid couplers ezinamandla aphezulu kuluhlu olubanzi ukusuka kwi-1.6MHz ukuya kwi-50GHz, ezisetyenziswa kakhulu kwiindawo ezininzi. Eli nqaku lizisa i-90 degrees hybrid coupler enamandla aphakathi kwe-50W kwiifrikhwensi eziqala kwi-4 ukuya kwi-12GHz.
