Zigawo za Microwave zikuphatikizapomicrowave zipangizo, yomwe imadziwikanso kuti zida za RF, monga zosefera, zosakaniza, ndi zina;Zimaphatikizanso zinthu zambiri zomwe zimapangidwa ndi ma microwave ozungulira ndi zida za microwave, monga tr components, up and down frequency conversion components, etc;Zimaphatikizanso ma subsystems, monga olandila.
Zigawo za Microwave m'gulu lankhondo zimagwiritsidwa ntchito kwambiri mu radar, kulumikizana, zida zamagetsi ndi zida zina zachitetezo cha dziko, komanso kufunika kwa zigawo za microwave, ndiye kuti, gawo lawayilesi, limachulukitsa kuchuluka kwa gawo lomwe likukula. zamakampani ankhondo;Komanso, m'munda wa Civil, amagwiritsidwa ntchito kwambirikuyankhulana opanda zingwe, galimotomillimeter wave radar,etc., amene ali gawo laling'ono ndi kufunika amphamvu ulamuliro paokha pakati ndi kumtunda kufika zipangizo zoyambira China ndi matekinoloje.Pali malo ochuluka kwambiri ophatikizana ndi asilikali, kotero padzakhala mwayi wochuluka wopezera ndalama mu zigawo za microwave.
Zigawo za Microwave zimagwiritsidwa ntchito kuzindikira ma frequency, mphamvu, gawo ndi masinthidwe ena azizindikiro za microwave.Pakati pawo, malingaliro a ma siginecha a microwave ndi RF ndi ofanana, ndiye kuti, ma analogi amasinthasintha omwe amakhala ndi ma frequency apamwamba, nthawi zambiri kuyambira makumi a megahertz mpaka mazana a gigahertz mpaka terahertz;Zigawo za Microwave nthawi zambiri zimakhala ndi mabwalo a microwave ndi zida zina za microwave.Njira yachitukuko chaukadaulo ndi miniaturization komanso mtengo wotsika.Njira zaukadaulo zowazindikiritsa zikuphatikiza Hmic ndi MMIC.MMIC ndi kupanga zigawo za microwave pa semiconductor chip.Digiri yophatikizira ndi madongosolo a 2 ~ 3 a ukulu kuposa Hmic.Nthawi zambiri, MMIC imodzi imatha kuzindikira ntchito imodzi.M'tsogolomu, kudzakhala kusakanikirana kwamitundu yambiri.Pomaliza, ntchito mlingo dongosolo adzakhala anazindikira pa Chip mmodzi, Iwo amakhala odziwika bwino RF SOC;Hmic imathanso kuwonedwa ngati kuphatikiza kwachiwiri kwa MMIC.Hmic makamaka imaphatikizapo filimu yophatikizika yophatikizika, filimu yopyapyala yophatikizika ndi sip yamapulogalamu.Thick film Integrated circuit akadali wamba microwave chigawo ndondomeko, amene ali ndi ubwino wa mtengo wotsika, mkombero waufupi ndi kusintha kusintha.Njira yopangira ma 3D yozikidwa pa LTCC ikhoza kuzindikiranso kuti miniaturization ya zigawo za microwave, ndipo ntchito yake m'gulu lankhondo ikuwonjezeka pang'onopang'ono.M'munda wankhondo, tchipisi tambiri tomwe timadya titha kupangidwa kukhala chip chimodzi.Mwachitsanzo, gawo lomaliza lamagetsi amplifier mu gawo la TR la radar yagawo lagawo lili ndi kuchuluka kwakukulu kwa mowa, ndipo ndikofunikira kuti likhale chip chimodzi;Mwachitsanzo, zinthu zambiri zazing'ono zosinthidwa makonda sizoyenera kupangidwa kukhala tchipisi chimodzi, koma makamaka mabwalo osakanizidwa ophatikizika.
Pamsika wankhondo, mtengo wa zida za microwave umakhala wopitilira 60% m'magawo a radar, kulumikizana ndi zida zamagetsi.Tidayerekeza malo amsika azinthu za microwave m'magawo a radar ndi zida zamagetsi.Pankhani ya radar, tidayerekeza mtengo wa radar wa mabungwe akuluakulu aku China ofufuza za radar, kuphatikiza 14 ndi 38 Institutes of CETC, 23, 25 ndi 35 Institutes of Aerospace Science and industry, 704 ndi 802 Institutes of Aerospace Science and Technology, 607 Institutes of AVIC, etc, Timayesa kuti malo amsika mu 2018 adzakhala 33billion, ndipo malo amsika a zigawo za microwave adzafika 20billion;29 Institutes of CETC, 8511 Institutes of Aerospace Science and industry ndi 723 Institutes of CSIC amaganiziridwa makamaka ngati njira zoyeserera zamagetsi.Malo onse amsika a zida zamagetsi zamagetsi ndi pafupifupi 8billion, pomwe mtengo wa zida za microwave ndi 5billion.Sitinaganizirepo zamakampani olankhulana pakadali pano chifukwa msika wamakampaniwa ndi wogawanika kwambiri.Pambuyo pake, tidzapitiriza kufufuza mozama ndi kuwonjezera.Malo amsika a zida za microwave mu radar ndi zida zamagetsi zokha zafika 25billion.
Msika wa anthu wamba umaphatikizansopokuyankhulana opanda zingwendi magalimoto millimeter wave radar.Pankhani yolumikizirana opanda zingwe, pali magawo awiri amsika: ma terminal ndi ma base station.RRU mu siteshoni yoyambira imakhala ndi zigawo za microwave monga ngati module, transceiver module, amplifier mphamvu ndi module fyuluta.Magawo a Microwave amachulukitsa kuchuluka kwa malo oyambira.M'malo opangira ma network a 2G, mtengo wa zida za RF umakhala pafupifupi 4% ya mtengo wa siteshoni yonse.Ndi chitukuko cha masiteshoni opita ku miniaturization, zida za RF muukadaulo wa 3G ndi 4G zakwera pang'onopang'ono mpaka 6% ~ 8%, ndipo gawo la masiteshoni ena amatha kufikira 9% ~ 10%.Chigawo chamtengo wapatali cha zida za RF mu nthawi ya 5g chidzakonzedwanso.Mu njira yolumikizirana yolumikizira mafoni, RF kutsogolo ndi chimodzi mwazinthu zofunika kwambiri.Zipangizo za RF muzitsulo zam'manja makamaka zimaphatikizapo amplifier mphamvu, duplexer, RF switch, fyuluta, amplifier otsika phokoso, ndi zina zotero.Mtengo wapakati mu nthawi ya 4G ndi pafupifupi $10, ndipo 5g ikuyembekezeka kupitilira $50.Msika wamagalimoto a millimeter wave radar ukuyembekezeka kufika madola 5 biliyoni aku US mu 2020, pomwe gawo lakutsogolo la RF ndi 40% ~ 50%.
Zida zankhondo za microwave ndi zigawo za microwave za Civil microwave zimalumikizana kwenikweni, koma zikafika pakugwiritsa ntchito zenizeni, zofunikira za zigawo za microwave ndizosiyana, zomwe zimapangitsa kulekanitsa zida zankhondo ndi zamagulu.Mwachitsanzo, zida zankhondo nthawi zambiri zimafunikira mphamvu zoyambira kuti zizitha kuzindikira zomwe zili kutali, komwe ndi poyambira mapangidwe awo, pomwe zida za anthu wamba zimayang'anira kwambiri magwiridwe antchito;Kuphatikiza apo, mafupipafupi amasiyananso.Pofuna kupewa kusokonezedwa, bandwidth yogwira ntchito ya asitikali ikukulirakulira, pomwe yachibadwidwe nthawi zambiri imakhala yopapatiza.Kuphatikiza apo, katundu wamba makamaka amagogomezera mtengo, pomwe zida zankhondo sizikhudzidwa ndi mtengo.
Ndi chitukuko cha teknoloji yamtsogolo, padzakhala kufanana kowonjezereka pakati pa ntchito zankhondo ndi anthu wamba, ndipo zofunikira zafupipafupi, mphamvu ndi zotsika mtengo zidzagwirizana.Tengani chitsanzo cha kampani yotchuka ya ku America yotchedwa qorvo.Sizimagwira ntchito ngati PA ya malo oyambira, komanso imapereka Power Amplifier MMIC kwa radar yankhondo, yomwe imagwiritsidwa ntchito mu Shipborne, airborne and land-based radar system, komanso njira zolumikizirana ndi zida zamagetsi.M'tsogolomu, dziko la China lidzawonetsanso mkhalidwe wa chitukuko chogwirizanitsa anthu wamba, ndipo pali mwayi waukulu woti asitikali atembenuke kukhala anthu wamba.
