Waa maxay ujeeddada resonator-ka godka? Shaandhada godka 2878-2882MHz ee Shabakadaha Casriga ah ee Dadban

Resonator-ka godka ayaa tamarta RF ku kaydiya qaab mowjad taagan ah wuxuuna ku soo celiyaa oo keliya inta jeer ee loogu talagalay.Shaandhada Godadka 2878-2882MHzWaxaa soo saaray Keenlion oo fadhigeedu yahay Chengdu, mabda'an wuxuu ku dabaqayaa godka wareega ee rubuc-hir ah: darbiyada lagu dahaadhay lacagta waxay qeexayaan qaabka eigen-ka 2880 MHz, halka tamarta ka baxsan band-ka ay dib ugu soo noqoto isha. Sababtoo ah Shaandhada godka 2878-2882MHz ma laha qaybo firfircoon, luminta gelinta waxay ku kooban tahay hagaha iyo khasaaraha dielectric-ka - qiimayaasha la cabbiray waxay ka hooseeyaan 1.0 dB daaqadda 4 MHz.

Naqshadeynta Farsamada iyo Waxqabadka

Shaandhada Godadka 2878-2882MHz waxay ka faa'iidaysataa godadka sare ee Q si loo gaaro khasaaro yar oo gelinta ah (≤1.0 dB) iyo xulasho gaar ah (>40 dB diidmo ±5 MHz ah). Hoyga yar, oo cabbirkiisu yahay 74 × 31 × 30 mm, wuxuu si aan kala go 'lahayn ugu dhex milmaa nidaamyada booska xaddidan sida UAV pods ama raadiyaha IoT ee yar. Shaandhada si kalsooni leh ayay ugu shaqeysaa heerkulka -55°C ilaa 85°C, iyadoo VSWR lagu hayo wax ka hooseeya 1.5:1 si loo yareeyo milicsiga calaamadaha. Cutub kasta wuxuu maraa 100% tijaabinta VNA otomaatiga ah si loo xaqiijiyo qeexitaannada sida maaraynta awoodda (20W CW) iyo qalooca geeska.

Baqshadda Farsamada

Cabbirka guud waa 74 × 30 × 31mm—ka yar inta badan aaladaha SAW—laakiin Shaandhada godka 2878-2882MHz waxay qabataa 20 W CW. Laba godad oo M2 ah oo ku yaal bartamaha 15 mm waxay u oggolaanayaan Shaandhada godka 2878-2882MHz in si toos ah loogu xidho derbi aluminium ah, taasoo meesha ka saaraysa baahida loo qabo qalab gaar ah oo kaydiya garaam qaali ah oo ku jira UAV ama dhismayaasha gacanta lagu hayo.

Laf-dhabarta Warshadda

Mashiinnada warshadda ee 20-ka sano ah ee Keenlion, saxamada, qalabka iyo alxanka Shaandhada godka 2878-2882MHz kasta oo saqaf hoostiis ah. Waqtiga rasaastu waa toddobo maalmood qaybaha caadiga ah, afartan iyo siddeed saacadood oo loogu talagalay dalabaadka soo noqnoqda. Lumitaanka gelinta ≤1.0 dB iyo diidmada ≥40 dB waxaa lagu dammaanad qaaday Shaandhada godka 2878-2882MHz kasta; muunado bilaash ah ayaa la soo diraa afartan iyo siddeed saacadood gudahood, kala-goysyada soo noqnoqda ee gaarka ahna waa la aqbalaa iyadoon wax MOQ ah la bixin.
