225MHz-700MHz UHF Tactical Filters | Shaandhooyinka RF-da ee la Dami karo ee Xirfadlayaasha ah

Dulmarka alaabta
Isgaadhsiinta casriga ah ee xirfadleyda ah ee wireless, nadiifinta muuqaalka iyo yaraynta faragelinta ayaa muhiim u ah ilaalinta daacadnimada xiriirka. Qiimahayada 225MHz - 700MHz UHF Tactical Filters waxaa si gaar ah loogu farsameeyay dalabaadka ganacsiga, badbaadada dadweynaha, iyo codsiyada kaabayaasha RF ee gaarka ah. Ka shaqaynta guud ahaan qaybta muhiimka ah ee UHF, filtarradani waxay keenaan doorasho gaar ah, luminta gelinta hoose, iyo maaraynta awood adag si loo hubiyo isku xidhka aan fiicneyn ee jawiga elektiroonigga ah ee cufnaanta sare leh.

Haddii nidaamkaagu u baahan yahay Filter Tunable-sare leh oo loogu talagalay idaacadaha moobiilka ee ku rakiban gaariga ama xal aadka u kooban ee Chip Tunable Filters ee cabbirka, culeyska, iyo awoodda (SwaP) ee xaddidan UAV-yada iyo aaladaha gacanta lagu qaato, xariiqda alaabadayadu waxay bixisaa isku hallayn aan isbarbardhig lahayn iyo waxqabadka goobta.

Tilmaamaha Muhiimka ah & Faa'iidooyinka
Daboolista UHF ballaaran: hagaajin joogto ah iyo shaandhaynta inta u dhaxaysa 225MHz ilaa 700MHz, oo daboolaysa xadhkaha isgaadhsiinta xirfadleyda iyo xaaladaha degdegga ah.

Tiknoolajiyada Filter Tunable Horukacsan: Waxay bixisa saxan sax ah, habayn inta jeer ee firfircoon si ay si dhaqsi leh ula qabsato bey'ada calaamadaha iyo la dagaalanka faragelinta wada jirka ee deegaanka.

Luminta Gelida Hoose & Diidmada Sare: Waxay kordhisaa kala duwanaanshaha nidaamka iyo hufnaanta calaamada iyadoo si adag u xakameynaysa buuqa ka baxsan band-yada, faragelinta baahinta, iyo iswaafajinta.

Dhisme Ruggedized: Loo dhisay si uu ugu adkaysto xaaladaha adag ee deegaanka, isaga oo hubinaya shoog gaar ah, gariir, iyo xasilloonida kulaylka ee goobta.

Descriptions	Address Code Definition: 10-bit parallel binary code A0–A9, compatible with CMOS and TTL logic levels. · A0–A7 control voltage levels: Logic Low: 0 ~ 0.7 V; Logic High: 2.4 ~ 3.3 V . · A0–A7 are used as the in-band address code. · A8 and A9 are used as band selection codes. Address Calculation (rounded to integer) Address Code={(fx-flow）/(fhigh-flow)}*250 Where: · fx: desired intrasegment center frequency · flow: lowest frequency in the segment · fhigh: highest frequency in the segment · 250: intrasegment steps If the calculated result contains a decimal fraction, it shall be rounded to the nearest integer.

Sawirka dulucda:

Codsiyada Bartilmaameedka
filtarradayada 225MHz - 700MHz UHF ayaa ah doorashada ugu habboon ee injineerada RF, hawlwadeenada shabakada, iyo isku dhafka nidaamka ee ku takhasusay:

Isgaarsiin Halis ah: Kobcinta shabakadaha badbaadada dadweynaha, raadiyaha jawaabta degdega ah, iyo isgaarsiinta dhulka ilaa hawada.

Yaraynta Faragelinta Wadajirka ah: Ka-hortagga dareenka qaataha ee jawiyada anteenada badan (goobaha la baahiyo, gawaarida talisyada wareega, iyo maraakiibta badda).

Nidaamyada aan cidna wadin (UAVs/UGVs): Ka faa'iidaysiga filtarrada Chip Tunable ee fudud si loo sugo, telemetry ganacsi ee fog iyo muuqaal muuqaal ah oo hoos-u-dhac ah.

Kormeerka Fog & Telemetry: shaandhaynta soo noqnoqoshada xawaaraha sare leh ee kaabayaasha warshadaha IoT iyo la socodka ishaarada.
