• Ntchito zina zamaukadaulo opanda zingwe zomwe titha kukuthandizani ndi:

​

- Makina achitetezo opanda zingwe

 

- Kuwongolera kutali kwa zida zamagetsi zamagetsi kapena zida zamalonda.

 

- Mafoni am'manja (mafoni ndi ma modemu):

 

- Wifi

 

- Kutumiza kwamagetsi opanda zingwe

 

- Zida zoyankhulirana ndi wailesi

 

- Zida zoyankhulirana zazifupi monga ma maikolofoni opanda zingwe, zowongolera zakutali, IrDA, RFID (Radio Frequency Identification), Wireless USB, DSRC (Dedicated Short Range Communications), EnOcean, Near Field Communication, Wireless Sensor Networks : ZigBee , EnOcean; Maukonde amdera lanu, Bluetooth, Ultra-wideband, makina apakompyuta opanda zingwe: Wireless Local Area Networks (WLAN), Wireless Metropolitan Area Networks (WMAN)...etc.

​

Zamagetsi za Microwave kuphatikiza ma silicon microwave diode, ma dot touch diode, schottky diode, PIN diode, varactor diode, step recovery diode, microwave Integrated circuits, splitters/combiners, mixers, directional couplers, detectors, I/Q modulators, filters, fixed attenuators, RF zosinthira, zosinthira gawo loyeserera, LNA, PA, masiwichi, zowongolera, ndi zochepetsera. Timapanganso ma microwave subassemblies ndi magulu malinga ndi zofuna za ogwiritsa ntchito. 

Ma microwave ndi mafunde a electromagnetic okhala ndi kutalika kwa mafunde kuyambira 1 mm mpaka 1 m, kapena ma frequency apakati pa 0.3 GHz ndi 300 GHz. Mitundu ya ma microwave imaphatikizapo ma ultra-high frequency (UHF) (0.3–3 GHz), super high frequency (SHF) (3– 30 GHz), komanso ma frequency apamwamba kwambiri (EHF) (30–300 GHz) siginecha.

ZINTHU ZOGWIRITSA NTCHITO:

 

Asanakhazikitsidwe ukadaulo wa fiber optic transmission, mafoni ambiri akutali ankayendetsedwa kudzera pa ma microwave point-to-point kudzera pamasamba ngati AT&T Long Lines. Kuyambira koyambirira kwa zaka za m'ma 1950, ma frequency division multiplexing adagwiritsidwa ntchito kutumiza matchanelo amafoni ofikira 5,400 pa tchanelo chilichonse chawayilesi ya microwave, ndi ma wayilesi ofikira khumi ophatikizidwa kukhala mlongoti umodzi wa hop kupita kumalo ena, komwe kunali mtunda wa makilomita 70. .

 

Ma protocol a LAN opanda zingwe, monga Bluetooth ndi mafotokozedwe a IEEE 802.11, amagwiritsanso ntchito ma microwave mu 2.4 GHz ISM band, ngakhale 802.11a imagwiritsa ntchito ISM band ndi U-NII ma frequency mu 5 GHz. Ntchito zokhala ndi zilolezo zautali wautali (mpaka pafupifupi 25 km) Ntchito za Wireless Internet Access zitha kupezeka m'maiko ambiri mumtundu wa 3.5–4.0 GHz (osati ku USA komabe).

 

Metropolitan Area Networks: Ma protocol a MAN, monga WiMAX (Worldwide Interoperability for Microwave Access) yozikidwa mu IEEE 802.16. Mafotokozedwe a IEEE 802.16 adapangidwa kuti azigwira ntchito pakati pa 2 mpaka 11 GHz. Zochita zamalonda zili mu 2.3GHz, 2.5 GHz, 3.5 GHz ndi 5.8 GHz.

 

Wide Area Mobile Broadband Wireless Access: Ma protocol a MBWA kutengera milingo monga IEEE 802.20 kapena ATIS/ANSI HC-SDMA (monga iBurst) adapangidwa kuti azigwira ntchito pakati pa 1.6 ndi 2.3 GHz kuti apereke mawonekedwe olowera ndikumangika ofanana ndi mafoni am'manja. koma ndi kuthekera kokulirapo kwa spectral.

 

Zina mwa mawonekedwe otsika a ma microwave frequency spectrum amagwiritsidwa ntchito pa Cable TV ndi intaneti pa chingwe cha coaxial komanso wailesi yakanema. Komanso maukonde ena amafoni, monga GSM, amagwiritsanso ntchito ma frequency otsika a ma microwave.

 

Wailesi ya Microwave imagwiritsidwa ntchito powulutsa ndi kutumizirana matelefoni chifukwa, chifukwa cha kutalika kwake kwakanthawi, tinyanga zowongolera kwambiri ndi zazing'ono motero ndizothandiza kuposa momwe zikadakhalira pamayendedwe otsika (mafunde ataliatali). Palinso bandiwifi zambiri mu microwave sipekitiramu kuposa zina zonse wailesi sipekitiramu; bandwidth yogwiritsidwa ntchito pansi pa 300 MHz ndiyochepera 300 MHz pomwe ma GHz ambiri amatha kugwiritsidwa ntchito pamwamba pa 300 MHz. Nthawi zambiri, ma microwave amagwiritsidwa ntchito m'nkhani za pawailesi yakanema kutumiza chizindikiro kuchokera kutali kupita ku wailesi yakanema m'galimoto yokhala ndi zida zapadera.

 

Ma C, X, Ka, kapena Ku Band a ma microwave sipekitiramu amagwiritsidwa ntchito pamayendedwe ambiri a satana. Ma frequency awa amalola bandwidth yayikulu kwinaku akupewa kuchulukana kwa UHF ndikukhala pansi pa mayamwidwe amlengalenga a EHF. Satellite TV mwina imagwira ntchito mu C band ya mbale yayikulu Fixed Satellite Service kapena Ku band ya Direct Broadcast Satellite. Njira zoyankhulirana zankhondo zimayendera makamaka ulalo wa X kapena Ku Band, pomwe gulu la Ka likugwiritsidwa ntchito ku Milstar.

KUGWIRITSA NTCHITO KUTI:

 

Ma radar amagwiritsa ntchito ma radiation a microwave kuti azindikire kuchuluka, kuthamanga, ndi mawonekedwe ena azinthu zakutali. Ma radar amagwiritsidwa ntchito kwambiri pazinthu monga kuwongolera kayendetsedwe ka ndege, kuyendetsa zombo, komanso kuwongolera liwiro la magalimoto.

 

Kupatula akupanga ma decices, nthawi zina ma Gunn diode oscillators ndi ma waveguides amagwiritsidwa ntchito ngati zowunikira zotsegulira zitseko zokha. Zambiri zakuthambo za wailesi zimagwiritsa ntchito ukadaulo wa microwave.

​

NAVIGATION SYSTEMS:

 

Global Navigation Satellite Systems (GNSS) kuphatikiza American Global Positioning System (GPS), Chinese Beidou ndi Russian GLONASS zimawulutsa ma siginecha oyenda m'magulu osiyanasiyana pakati pa pafupifupi 1.2 GHz ndi 1.6 GHz.

​

MPHAMVU:

 

Ovuni ya microwave imadutsa (yopanda ionizing) ma radiation a microwave (pafupifupi 2.45 GHz) kudzera muzakudya, zomwe zimapangitsa kutentha kwa dielectric ndi kuyamwa kwa mphamvu m'madzi, mafuta ndi shuga zomwe zili m'zakudya. Mavuni a Microwave adadziwika pambuyo popanga maginito otsika mtengo.

 

Kutentha kwa microwave kumagwiritsidwa ntchito kwambiri m'mafakitale poyanika ndi kuchiritsa zinthu.

 

Njira zambiri zopangira ma semiconductor amagwiritsa ntchito ma microwave kuti apange plasma pazinthu monga reactive ion etching (RIE) ndi plasma-enhanced chemical vapor deposition (PECVD).

 

Ma Microwaves atha kugwiritsidwa ntchito kufalitsa mphamvu pamtunda wautali. NASA idagwira ntchito mzaka za m'ma 1970 ndi koyambirira kwa 1980 kuti ifufuze kuthekera kogwiritsa ntchito makina a Solar Power Satellite (SPS) okhala ndi zida zazikulu zadzuwa zomwe zimayatsira mphamvu padziko lapansi kudzera pa ma microwave.

 

Zida zina zopepuka zimagwiritsa ntchito mafunde a millimeter kutenthetsa khungu lopyapyala la munthu mpaka kutentha kosasunthika kupangitsa munthu yemwe akumufunayo asamuke. Kuphulika kwa masekondi awiri kwa 95 GHz wolunjika kumatenthetsa khungu mpaka kutentha kwa 130 ° F (54 ° C) pakuya kwa 1/64th inchi (0.4 mm). United States Air Force ndi Marines amagwiritsa ntchito mtundu uwu wa Active Denial System.
