Planar AFAR muaj qhov txiaj ntsig zoo txog qhov hnyav thiab qhov loj piv rau lwm cov kev daws teeb meem. Qhov hnyav thiab tuab ntawm AFAR lub vev xaib raug txo los ntawm ob peb zaug. Qhov no tso cai rau lawv siv rau hauv qhov me me qhov radar homing lub taub hau, ntawm UAVs hauv nkoj thiab rau chav kawm tshiab ntawm cov kav hlau txais xov tshuab - cov kav hlau txais xov raws kab ke, piv txwv li. rov ua dua cov duab ntawm cov khoom. Xws li cov phiaj, tsim nyog los tsim kev sib ntaus sib tua tom ntej, thib rau, tiam.
JSC "NIIPP" tab tom tsim cov phiaj xwm sib koom ua ke tau txais thiab xa AFAR cov qauv siv LTCC-ceramics thev naus laus zis, uas suav nrog txhua yam ntawm AFAR daim ntaub (cov ntsiab lus tseem ceeb, cov kav hlau txais xov emitters, microwave teeb liab xa tawm thiab tswj cov tshuab, lub zog thib ob uas tswj cov tswj hwm digital. nrog kev sib txuas hauv Circuit Court, ua kua txias) thiab yog cov cuab yeej ua tiav. Cov qauv tuaj yeem sib xyaw ua ke rau hauv cov kav hlau txais xov ntawm txhua qhov loj, thiab nrog qhov tseem ceeb sib xyaw ua ke, qhov xav tau yam tsawg kawg nkaus tau tsim los ntawm cov qauv txhawb nqa, uas yuav tsum koom ua ke xws li cov qauv. Qhov no ua rau nws yooj yim dua rau cov neeg siv kawg los tsim AFAR raws li cov qauv no.
Ua tsaug rau thawj qhov kev daws teeb meem thiab siv cov ntaub ntawv tshiab thiab cog lus, xws li cov hluav taws kub sib xyaw ua kom sov qis (LTCC), cov khoom siv sib xyaw, ntau txheej microchannel ua kua txias ua qauv tsim los ntawm JSC NIIPP, kev sib xyaw ua ke dav dav APMs yog qhov txawv los ntawm:
JSC "NIIPP" tau npaj los txhim kho thiab teeb tsa cov txheej txheem ntawm cov phiaj xwm tau txais, xa thiab xa AFAR cov qauv ntawm S, C, X, Ku, Ka bands, raws li qhov xav tau ntawm cov neeg siv khoom txaus siab.
JSC NIIPP muaj txoj haujlwm tshaj lij tshaj plaws hauv Russia thiab hauv ntiaj teb hauv kev txhim kho cov phiaj xwm APAR modules siv LTCC-ceramics thev naus laus zis.
Tsocai:
Cov txiaj ntsig ntawm qhov nyuaj ntawm kev tshawb fawb thiab kev txhim kho hauv thaj tsam ntawm kev tsim GaAs thiab SiGe microwave monolithic integrated circuits, cov tsev qiv ntawv ntawm cov ntsiab lus thiab CAD cov qauv, nqa tawm ntawm Tomsk University ntawm kev tswj cov tshuab thiab xov tooj cua hluav taws xob.
Hauv xyoo 2015, REC NT tau pib ua haujlwm ntawm kev tsim lub microwave MIC rau thoob ntiaj teb cov pab pawg sib txuas ntau lub suab sib txuas (L-, S- thiab C-bands) hauv daim ntawv ntawm "txheej txheem ntawm nti" (SoC). Txog rau hnub tim, raws li 0.25 μm SiGe BiCMOS thev naus laus zis, MISs ntawm cov cuab yeej siv hluav taws xob sab hauv qab no (ntau zaus 1-4.5 GHz) tau tsim: LNA, tov khoom, ntsuas cov ntsuas hluav taws xob (DCATT), ntxiv rau DCATT tswj Circuit.
Cov Zis: Nyob rau yav tom ntej, "teeb meem" ntawm radar rau Yak-130, UAV, tus nrhiav rau KR thiab OTR yuav raug daws ntawm theem hnyav heev. Nrog qib siab ntawm qhov tshwm sim, nws muaj peev xwm xav tias "cov khoom lag luam uas tsis muaj kev sib piv hauv ntiaj teb." AFAR "hauv pawg hnyav" 60-80 kg (txog qhov yuav tsum tau ua rau Yak-130 220kg-270kg radar pawg kuv yuav nyob ntsiag to)? Yog Yooj Yim. Puas muaj ib lub siab xav kom tau tag nrho 30 kg ntawm AFAR?
Lub sijhawm no … Thaum "qhov no yog qhov xwm txheej":
Tseem tsis tau muaj dav hlau ya dav hlau. Tsoomfwv Lavxias tseem tsis tau xav txog kev muag nws rau Tuam Tshoj thiab Indonesia (ntawm no nws yuav zoo dua los daws nrog SU-35), txawm li cas los xij … Txawm li cas los xij, tus sawv cev ntawm Lockheed Martin thiab "tus lej" kws tshaj lij "los ntawm Russia twb tau kwv yees yav dhau los: nws yuav kim, yuav muaj teeb meem nrog kev muag khoom rau Tuam Tshoj thiab Indonesia. Los ntawm keeb kwm ntawm "rov qab" ntawm Lavxias / Soviet avionics rau "ntau tus" kws tshaj lij "los ntawm Russia, rau kev siv:
GaN thiab nws cov kev daws teeb meem yog ntawm cov khoom siv nrov tshaj plaws thiab cog lus hauv cov khoom siv hluav taws xob niaj hnub no. Kev ua haujlwm nyob rau hauv cov lus qhia no tau ua tiav thoob plaws ntiaj teb, kev sib tham thiab kev sib tham tau raug teeb tsa tsis tu ncua, uas pab txhawb kev txhim kho thev naus laus zis sai rau tsim cov khoom siv hluav taws xob thiab optoelectronic raws li GaN. Kev ua tiav tau pom ob qho tib si hauv cov qauv ntawm LED teeb tsa raws GaN thiab nws cov kev daws teeb meem, thiab hauv cov yam ntxwv ntawm PPMs raws li gallium nitride - kev txiav txim ntawm qhov ntau dua li ntawm cov khoom siv gallium arsenide.
Thaum lub sijhawm xyoo 2010, kev hloov pauv hauv thaj tsam nrog Ft = 77.3 GHz thiab Fmax = 177 GHz nrog qhov nce ntawm lub zog ntau dua 11.5 dB ntawm 35 GHz. Raws li cov transistors no, thawj zaug hauv tebchaws Russia, MIS tau tsim thiab ua tiav rau peb-theem lub zog siv hluav taws xob hauv qhov ntau zaus 27–37 GHz nrog Kp> 20 dB thiab lub zog tso zis ntau tshaj ntawm 300 mW hauv ib hom pulse. Raws li Tsoom Fwv Lub Hom Phiaj Cov Hom Phiaj "Kev Txhim Kho Cov Khoom Siv Hluav Taws Xob Base thiab Xov Tooj Cua Hluav Taws Xob", kev txhim kho ntxiv ntawm kev tshawb fawb thiab tshawb fawb hauv qhov kev taw qhia no yog xav tau. Tshwj xeeb, kev txhim kho ntawm InAlN / AlN / GaN heterostructures rau kev tsim cov cuab yeej nrog kev ua haujlwm nquag ntawm 30-100 GHz, nrog kev koom tes ntawm cov tuam txhab ua lag luam hauv tsev thiab cov koom haum (FSUE NPP Pulsar, FSUE NPP Istok, ZAO Elma-Malakhit, JSC "Svetlana-Rost", ISHPE RAS, thiab lwm yam).
Parameters ntawm kev tsim vaj tsev sib txawv thiab transistors nrog lub qhov rooj zoo tshaj qhov ntev raws li lawv (xam):
Nws tau sim sim pom tias rau Ka-zaus ntau, hom 2 heterostructures nrog tb = 15 nm yog qhov zoo tshaj, uas niaj hnub no V-1400 ("Elma-Malachite") ntawm SiC substrate muaj qhov zoo tshaj plaws, uas ua kom pom kev tsim ntawm transistors nrog qhov pib tam sim no txog 1.1 A / mm ntawm qhov nqes hav siab tshaj ntawm 380 mA / mm thiab txiav tawm qhov hluav taws xob ntawm -4 V. / tB = 12) muaj fT / fMAX = 62/130 GHz thaum tsis muaj cov teebmeem luv-channel, uas yog qhov zoo tshaj rau PA PA-band. Nyob rau tib lub sijhawm, transistors nrog LG = 100 nm (LG / tB = 8) ntawm tib lub heterostructure muaj ntau zaus ntau dua fT / fMAX = 77/161 GHz, uas yog, lawv tuaj yeem siv tau ntau dua V- thiab E- bands, tab sis vim qhov cuam tshuam luv-channel tsis pom zoo rau cov zaus no.
Cia peb pom ua ke tshaj plaws "neeg txawv tebchaws" thiab peb cov radars:
Retro: lub pharaoh-M radar, uas tam sim no yog ib yam ntawm yav dhau los (nws tau npaj los nruab nws ntawm Su-34, 1.44, Berkut). Beam txoj kab uas hla 500 hli. Tsis-equidistant HEADLIGHTS "Phazotron". Qee zaum nws kuj tseem hu ua "Spear-F".

LTCC cov khoom siv:
Tsawg Kub Kub Co-Fired Ceramic (LTCC) yog qhov kub tsis tshua muaj hluav taws xob siv hluav taws xob tshuab siv los tsim cov khoom siv microwave, suav nrog Bluetooth thiab WiFi cov qauv hauv ntau lub xov tooj. Nws tau paub dav rau nws siv hauv kev tsim khoom ntawm AFAR radars ntawm lub cim thib tsib fighter T-50 thiab lub cim thib plaub tank T-14.
Lub hauv paus ntawm thev naus laus zis nyob hauv qhov tseeb tias lub cuab yeej raug tsim tawm zoo li lub rooj tsav xwm luam tawm, tab sis nyob hauv cov iav yaj. "Tsawg-kub" txhais tau tias ci tau ua tiav ntawm qhov kub ib puag ncig 1000C tsis yog 2500C rau HTCC thev naus laus zis, thaum nws muaj peev xwm siv tsis tau cov khoom kub siab kub heev los ntawm molybdenum thiab tungsten hauv HTCC, tab sis kuj pheej yig tooj liab hauv kub thiab nyiaj cov hlau
