Abstract:
Iyada oo ah qayb aasaasi ah oo ku jirta injineernimada microwave, anteenooyinka geesku waxay ku guulaysteen korsasho aan la qiyaasi karin oo ku saabsan codsiyada kala duwan sababtoo ah sifooyinka korantada ee gaarka ah iyo isku halaynta qaabdhismeedkooda. Farsamadan kooban waxay eegaysaa sida ay ugu badan yihiin nidaamyada casriga ah ee RF.
Faa'iidooyinka Farsamada:
Waxqabadka Broadband: Muujinta sifooyinka shucaaca joogtada ah ee guud ahaan xajmiyada badan ee octave (sida caadiga ah 2:1 ama ka weyn), anteenooyinka geesku waxay u adeegaan heerarka tixraaca11dBi anteenohababka cabbirida kala duwan.
Anteenada Horn Broadband(0.5-6GHz,11dBi)
Broadband Dual Polarized Horn Antenada (0.8-12GHz, 11dBi)
Anteenada Horn Broadband (0.6-6GHz,11dBi)
RF Miso11dbi taxane alaab
Astaamaha Shucaaca Saxda ah:
Xasilooni Balaadhan oo dhan ≤ ± 2° guud ahaan baaxada baaxadda hawlgalka
Takoorka-polarization-ka> 25dB
VSWR <1.25:1 iyada oo la hagaajiyayvacuum brazingbeen abuurasho
Sharafta Dhismaha:
Aluminium aluminium heerka milatariga ah oo leh <5μm qallafsanaan dusha sare ah
Xiritaanka Hermetic ee hawlgalka deegaanka ee adag (-55°C ilaa +125°C)
Falanqaynta Codsiyada:
Nidaamyada Raadaarka:
PESA Raadaarka: Waxay u adeegtaa sidii curiye quudin oo loogu talagalay arrays dadban
AESA Radar: Waxaa loo isticmaalaa is-habaynta hoose iyo tijaabada goobta u dhow
Nidaamyada cabbiraadda:
Heerka faa'iidada aasaasiga ah eeImtixaanka anteenada RFqalabka
Xaqiijinta kala duwanaanta goobta fog
Imtixaanka EMI/EMC ee MIL-STD-461G
Nidaamyada Isgaarsiinta:
Saldhigga dhulka ee dayax-gacmeedka ayaa quudiya
Isku xirka microwave-ka-bar-baarka
5G mmWave saldhigga saldhigga
Qiimaynta Isbarbardhigga:
Iyadoo anteenooyin kale ay jiraan, qaabeynta geesku waxay ilaalinayaan awoodda sababtoo ah:
Qiimaha sare/saamiga waxqabadka
Raadinta jaangooyooyinka la aasaasay
Isku halaynta la xaqiijiyay (> 100,000 hr MTBF)
Gabagabo:
Isku dhafka gaarka ah ee anteenada geeska ee saadaalinta korantada, adkeysiga farsamada, iyo soo saarista cabbirka ayaa hubisa sii faafitaankeeda injineerinka microwave-ka. Horumarka socda ee vacuum brazing iyo machiing sax ah ayaa sii wanaajinaya ku-dhaqanka nidaamyada jiilka soo socda.
