Iyo indasitiri yeRF ichataridzika sei mumakore gumi?

Kubva pamafoni akangwara kuenda kusevhisi masevhisi uye GPS RF tekinoroji chinhu chehupenyu hwazvino.Zvakatekeshera kwese zvekuti vazhinji vedu tinozvitora sezvisina basa.

RF engineering inoenderera mberi nekufambisa budiriro yepasirese mumashandisirwo mazhinji munzvimbo dzeveruzhinji uye dzakazvimirira.Asi kufambira mberi kweruzivo rwokugadzira zvinhu kunokurumidza zvokuti dzimwe nguva zvakaoma kufanotaura kuti nyika ichange yakaita sei mumakore mashomanana.Kubva muna 2000, vangani vanhu mukati nekunze kweindasitiri vangafungidzira kuti vaizoona vhidhiyo yekufambisa panharembozha yavo mumakore gumi?

Sezvineiwo, isu tafambira mberi zvakadaro munguva pfupi, uye hapana chiratidzo chekudzikira mukudiwa kweiyo RF tekinoroji.Makambani akazvimirira, hurumende nemauto pasirese ari kukwikwidza kuti ave neazvino maRF ekuvandudza.

Muchikamu chino, tichapindura mibvunzo inotevera: iyo RF indasitiri ichaita sei mumakore gumi?Ndeapi mafambiro azvino uye eramangwana uye tinoramba tiri mberi sei?Tinowana sei vatengesi vanoona zvinyorwa pamadziro uye vanoziva kuti zvinhu zviri kufamba sei?

Inouya RF indasitiri maitiro uye ramangwana reRF Technology.Kana iwe wanga uchiteerera kune budiriro mumunda weRF, iwe unogona kuziva kuti iri kuuya 5g shanduko ndeimwe yekuchinja kukuru pakatarisana.Pakazosvika 2027, ichokwadi kuti tinogona kutarisira kuti 5g network yakatangwa uye ichimhanya kwenguva yakati, uye zvinotarisirwa nevatengi zvekumhanya kwenhare uye kuita zvichange zvakakwirira kupfuura izvozvi.Sezvo vanhu vakawanda pasirese vachishandisa mafoni akangwara, kudiwa kwedata kucharamba kuchikwira, uye tsika yechinyakare bandwidth iri pazasi 6GHz haina kukwana kutarisana nedambudziko iri.Imwe yemayedzo ekutanga eruzhinji ye5g yakaburitsa kumhanya kunoshamisa kwegumi GB pasekondi inosvika 73 GHz.Hapana kupokana kuti 5g ichapa mheni nekukurumidza kuvharika pamafrequency aimboshandiswa kumauto uye satellite application.

5g network ichaita basa rinokosha mukukurumidzira kutaurirana pasina waya, kuvandudza chaiyo chaiyo uye kubatanidza mamirioni emidziyo yatinoshandisa nhasi.Ichava kiyi yekuvhura iyo IoT.Zvigadzirwa zvisingaverengeki zvemumba, zvemagetsi zvinobatika nemaoko, zvishandiso zvinopfekwa, marobhoti, masensa, uye mota dzeautopilot zvichabatanidzwa kuburikidza nekusanzwa kwekumhanya kwetiweki.

Ichi chikamu chezvairehwa naEric Schmidt, sachigaro mukuru wealphabet, Inc, paakataura kuti Indaneti sezvatinoziva yaizo“nyangarika”;Ichave yazara uye yakabatanidzwa mune ese maturusi atinoshandisa zvekuti isu hatigone kusiyanisa kubva kune "hupenyu chaihwo".Kufambira mberi kweRF tekinoroji ndiyo mashiripiti anoita kuti zvese izvi zviitike.

Mauto, aerospace uye satellite application:

Munyika yekukurumidza kufambira mberi kwehunyanzvi uye kusagadzikana kwezvematongerwo enyika, kudiwa kwekuchengetedza hukuru hwemauto kwakasimba kupfuura nakare kose.Munguva pfupi iri kutevera, mari yepasi rose yehondo yemagetsi (EW) inotarisirwa kudarika US $9.3 bhiriyoni panosvika 2022, uye kudiwa kwemauto eRF uye kufambira mberi kwehunyanzvi hwemicrowave kuchawedzera.

Kusvetukira kukuru mu "electronic warfare" tekinoroji

Hondo yemagetsi ndeye "kushandisa electromagnetic (EM) uye inotungamira simba kudzora iyo electromagnetic spectrum kana kurwisa muvengi".(mwrf) makuru ekudzivirira makondirakiti achabatanidza akawanda uye akawanda emagetsi ehondo matekinoroji muzvigadzirwa zvavo mumakore gumi anotevera.Semuenzaniso, Lockheed Martin mutsva weF-35 murwi ane hunyanzvi hwemagetsi ehondo, izvo zvinogona kukanganisa mafambiro evavengi uye kudzvanya radar.

Mazhinji eaya masystem matsva eEW anoshandisa gallium nitride (GAN) zvishandiso kubatsira kuzadzisa zvavanoda masimba emagetsi, pamwe neakaderera ruzha amplifiers (LNAs).Uye zvakare, kushandiswa kwemotokari dzisina munhu pasi, mumhepo uye mugungwa kuchawedzerawo, uye yakaoma RF mhinduro dzinodiwa kutaurirana uye kutonga michina iyi pane yekuchengetedza network.

Munzvimbo dzemauto nedzekutengesa, kudiwa kwepamusoro satellite kutaurirana (SATCOM) RF mhinduro kuchawedzerawo.SpaceX's yepasi rose yeWiFi purojekiti ipurojekiti inoshuvira inoda advanced RF engineering.Iyo purojekiti ichada anopfuura 4000 mu orbit satellite kuti atumire isina waya Internet kuvanhu pasi rese paKu naKa vachishandisa 10-30 GHz frequency - bhendi renji - iyi ingori kambani!
