Jenereta yamagetsi ya microwave yolimba ndi chipangizo chamagetsi chomwe chimagwiritsa ntchito zida za semiconductor monga ma Gunn diode, ma IMPATT diode, ma transistors a FET, ma transistors a HEMT, ndi zina zotero kuti apange mafunde a electromagnetic a frequency microwave (nthawi zambiri amatanthauza 300MHz ~ 300GHz).

Ndi yosiyana kwambiri ndi ma microwave achikhalidwe "zipangizo zamagetsi zotsukira mpweya" monga ma magnetron, ma wave tubes oyendayenda, ndi ma klystrons. Zipangizo zakale zimadalira kuyenda kwa ma electron aulere mu vacuum kuti apange ma microwave, pomwe ma microwave power generators a boma amadalira kwathunthu mawonekedwe a zinthu zolimba za semiconductor, zomwe zimapangitsa kugwedezeka kudzera mu kayendedwe ndi kusintha kwa mphamvu kwa ma electron mkati mwa kapangidwe ka semiconductor lattice.

Makhalidwe:

1. Kukula kochepa komanso kulemera kopepuka: Pakati pake ndi chip ya semiconductor, yomwe siifuna machubu otayira mpweya kapena magetsi amphamvu kwambiri, zomwe zimapangitsa chipangizo chonsecho kukhala chocheperako komanso chosavuta kuchiphatikiza mu makina amakono amagetsi.
2. Voliyumu yogwira ntchito yochepa komanso chitetezo champhamvu: Nthawi zambiri pamafunika ma volts ochepa mpaka ma volts makumi ambiri a DC low voltage, pomwe zida zamagetsi zotsukira mpweya nthawi zambiri zimafuna ma volts zikwizikwi a high voltage. Izi zimapangitsa kuti ikhale yotetezeka komanso kapangidwe ka mphamvu kakhale kosavuta.
3. Moyo wautali komanso wodalirika kwambiri: Popanda zinthu zogwiritsidwa ntchito monga ma filaments a cathode, moyo wa zipangizo za semiconductor ndi wautali kwambiri, umafika maola makumi kapena mazana ambiri, kuposa machubu achikhalidwe a microwave.
4. Kuyera kwa ma spectrum ndi kukhazikika kwa ma frequency: Makamaka magwero olimba omwe amagwiritsa ntchito ukadaulo wa phase-locked loop (PLL), amatha kupanga ma microwave signaling oyera komanso okhazikika kwambiri okhala ndi phokoso lotsika.
5. Liwiro losinthira mwachangu komanso kulamulira kosinthasintha: Mafupipafupi otulutsa, gawo, ndi kukula kwake zimatha kusinthidwa mwachangu komanso molondola kudzera mu voltage (voltage controlled oscillator VCO) kapena ma signals a digito, zomwe zimapangitsa kuti zikhale zosavuta kukwaniritsa kusintha kovuta komanso kusinthasintha.
6. Kukana kugwedezeka ndi kugwedezeka bwino: Ndi kapangidwe kolimba, palibe zipolopolo zagalasi kapena ulusi wosalimba, zomwe zimapangitsa kuti zikhale zosavuta kusintha ku malo ovuta amakina.

Ntchito:

1. Radar core yamakono: Imagwiritsidwa ntchito kwambiri mu automotive millimeter wave radar, military phased array radar, ndi zina zotero, kuti ipezeke molondola komanso ipange scanning yachangu.
2. Maziko olumikizirana opanda zingwe: Ndi gawo lofunika kwambiri la malo oyambira a 5G/6G, kulumikizana kwa satellite, ndi zida zotumizira ma microwave, zomwe zimayang'anira kupanga ma signalo onyamula ma frequency apamwamba.
3. Kuyesa ndi kuyeza molondola: Monga gwero la chizindikiro, ndi "mtima" wa zida zapamwamba monga zowunikira za spectrum ndi zowunikira za netiweki, zomwe zimawonetsetsa kuti mayeso ndi olondola.
4. Zida zamafakitale ndi zasayansi: Zimagwiritsidwa ntchito potenthetsera, kuumitsa mafakitale, komanso zotenthetsera tinthu tating'onoting'ono ndi kutentha kwa plasma pazida zolumikizira nyukiliya m'magawo ofufuza asayansi.
5. Chitetezo ndi nkhondo zamagetsi: Amagwiritsidwa ntchito popanga zithunzi zachitetezo cha anthu ndi makina ojambulira pankhondo zamagetsi, kupanga zizindikiro zovuta kuti zisokoneze.

Qualwaveimapereka jenereta yamagetsi ya microwave yolimba yokhala ndi pafupipafupi ya 2.45GHz. Zogulitsa zathu zimagwiritsidwa ntchito kwambiri m'malo ambiri.
