Mzere Wochedwa Wolamulidwa ndi Digito, 0.1 ~ 18GHz, Kuchedwa kwa 1.25 ~ 78.75ps, Gawo 1.25ps

Mizere Yochedwa Yolamulidwa ndi Digito ndi zipangizo zamagetsi zomwe zimatha kupereka njira yolondola komanso yokonzedwa yowongolera kuchedwa kwa nthawi ya ma siginecha a RF/microwave. Mwa kuphatikiza ma cell angapo ochedwa ndi ma switch a RF othamanga kwambiri, amasintha chizindikiro cholowera pakati pa njira zotumizira zautali wosiyanasiyana pansi pa ma siginecha owongolera digito, motero amapeza kuchedwa koyambirira pa zotulutsa. Poyerekeza ndi ma shifter achikhalidwe, mizere yochedwa yolamulidwa ndi digito imapereka "kuchedwa kwa nthawi yeniyeni", moyenera kupewa zotsatira za squint zomwe zimachitika mu ma siginecha a wideband panthawi yowunikira beam. Ndi zigawo zofunika kwambiri pakukhazikitsa ma arrays a wideband phased, ma radar apamwamba, ndi machitidwe oyesera molondola kwambiri. Izi ndi chiyambi cha mawonekedwe ndi ntchito za mizere yochedwa yolamulidwa ndi digito ya 0.1 ~ 18GHz.

Mawonekedwe:

1. Mafupipafupi ogwiritsira ntchito a Ultra-wideband
Ma frequency ogwiritsira ntchito amakhudza 0.1 ~ 18GHz, kuyambira L-band mpaka Ku-band, zomwe zimakwaniritsa zofunikira pakugwiritsa ntchito ma signal system ambiri a RF/microwave. Kudzera mu kapangidwe kowonjezera ka maselo ochedwa mkati, mphamvu ya frequency shift pa magwiridwe antchito ochedwa imachepetsedwa bwino, ndikusunga mawonekedwe okhazikika a kuchedwa pa band yonse.
2. Kuchedwa kolondola kwambiri komwe kungakonzedwe
Kuwongolera kwa digito kumalola kusintha kolondola kwa kuchedwa, ndi sitepe yochedwa yochepera 1.25ps ndi kuchuluka konse kwa kuchedwa mpaka 78.75ps. Kulondola kwa kuchedwa kwanthawi zonse kumafika ±4ps, zomwe zimakwaniritsa mapulogalamu omwe amafuna nthawi yayitali kwambiri.
3. Kutayika kochepa kwa malo olowera komanso VSWR yabwino
Imasunga kutayika kochepa kwa zoyikapo pa band yonse, yothandiza pa bajeti ya ulalo wa dongosolo komanso umphumphu wa chizindikiro.
4. Kuchepetsa mphamvu ya thupi ndi kuphatikiza kwakukulu
Ukadaulo wapamwamba wa chingwe chotumizira ma microwave ndi njira zopangira ma semiconductor zimaphatikiza chingwe chokulirapo kapena mizere yochedwa ya coaxial kukhala phukusi laling'ono, zomwe zimapangitsa kuti kuchedwa kukhazikike, kuthekera koletsa kusokonezedwa, komanso kuphatikiza kosavuta kwa makina, kuthana ndi zofooka za mizere yochedwa yachikhalidwe monga kukula kwakukulu, kutayika kwakukulu, komanso kufalikira kwakukulu.

Mapulogalamu:

1. Radar yolumikizidwa ndi gulu lalikulu
Mu makina a radar okhala ndi ma radar ambiri, malo olowera a antenna amayendayenda pafupipafupi chifukwa cha zotsatira za kutsegula. Mizere yochedwa yolamulidwa ndi digito imapereka chipukuta misozi chenicheni cha nthawi, ndikuchotsa bwino kugwedezeka kwa beam ndikuwonjezera kulondola kwa radar komanso kutsimikiza kwa angular. Ndi zigawo zazikulu mu RF front-end subarrays ya ma radar okhala ndi ma radar.
2. Machitidwe olumikizirana ndi kukonza zizindikiro
Mu kulumikizana kwa digito, kulumikizana kwa satellite, ndi machitidwe ankhondo zamagetsi, mizere yochedwetsa yolamulidwa ndi digito imakwaniritsa kusiyana kwa kuchedwetsa pakati pa njira zosiyanasiyana zazizindikiro, kukwaniritsa kulumikizana kwa nthawi, kulumikizana kwa wotchi, ndi kukonza magawo, ndikukweza magwiridwe antchito a dongosolo la zolakwika za bit ndi mtundu wa chizindikiro.
3. Kuyesa ndi kuwerengera ma radar
Mu kuyesa kwa labotale ndi kuwerengera makina a radar, mizere yochedwa yolamulidwa ndi digito imakhala ngati magwero olondola kwambiri a nthawi, kutsanzira zizindikiro za echo kuchokera ku zolinga zomwe zili pamtunda wosiyana, kuthandizira kutsimikizira magwiridwe antchito a radar, kuyesa mawonekedwe a antenna, ndi ntchito zodziyesa zokha zamakina.
4. Zida zamagetsi zomenyera nkhondo ndi zofufuza
Mu machitidwe owunikira ndi kutsekereza zamagetsi, mizere yochedwetsa yolamulidwa ndi digito imatha kupanga kusiyana kwa nthawi kuti ilole kusungira ndi kutumiza zizindikiro, kupanga kutsekereza kogwirizana, ndi kusiyana kwa nthawi yofika (TDOA), zomwe zimapangitsa kuti zikhale zofunikira kwambiri powongolera kuchedwa kwa nthawi molondola mu zida zamagetsi zankhondo.
5. Ma module a T/R
Mu ma module a T/R a ma antenna olumikizidwa pang'onopang'ono, mizere yochedwa yolamulidwa ndi digito imagwira ntchito ndi ma code a beam steering system kuti ikwaniritse kuwongolera kolondola kwa zizindikiro za gawo lililonse la array, motero kukwaniritsa kupanga kwa beam ndi kusanthula mwachangu kwa beam. Mapulogalamu oterewa amafunikira mizere yochedwa yokhala ndi bandwidth yayikulu, kutayika kochepa kwa insertion, kukhazikika bwino kwa gawo, komanso kuthekera kosintha njira mwachangu.

Qualwave Inc. imapereka intaneti yothamanga kwambiri komanso yosinthasinthamizere yochedwetsa yolamulidwa ndi digitondi ma frequency mpaka 18GHz. Nkhaniyi ikubweretsa mzere wochedwa wolamulidwa ndi digito wokhala ndi ma frequency a 0.1 ~ 18GHz, mtunda wochedwa wa 1.25 ~ 78.75ps, sitepe ya 1.25ps.
