Chinoburitsa simba rema microwave chinonzi Solid-state mudziyo wemagetsi unoshandisa michina ye semiconductor yakaita seGunn diodes, IMPATT diodes, FET transistors, HEMT transistors, nezvimwewo kugadzira ma microwave frequency electromagnetic waves (anowanzoreva 300MHz ~ 300GHz).

Zvakasiyana zvachose nemidziyo ye "electrical vacuum devices" yema microwave yechinyakare yakaita semagnetrons, traveling wave tubes, uye klystrons. Midziyo yechinyakare inoshandisa ma "free electrons" mu vacuum kuti igadzire ma microwave, nepo ma solid-state power generators achishandisa zvizere hunhu hwezvinhu zvakasimba zve semiconductor, zvichigadzira oscillations kuburikidza nekufamba uye simba rekuchinja kwema electrons mukati me semiconductor lattice structure.

Hunhu:

1. Saizi diki uye huremu hwakareruka: Chidimbu chepakati i semiconductor chip, chisingade machubhu evacuum kana magetsi ane voltage yakawanda, zvichiita kuti mudziyo wese uve mudiki uye nyore kuubatanidza mumasisitimu emagetsi emazuva ano.
2. Voltage shoma yekushanda uye kuchengetedzeka kwakanyanya: Kazhinji chete magetsi mashoma eDC anodiwa, nepo michina yemagetsi inobvisa magetsi inowanzoda zviuru zvevolts zvevoltage yakakwira. Izvi zvinoita kuti ive yakachengeteka uye dhizaini yemagetsi ive nyore.
3. Kugara kwenguva refu uye kuvimbika kwakanyanya: Pasina zvinhu zvinoshandiswa senge cathode filaments, hupenyu hwepfungwa hwemidziyo ye semiconductor hwakareba zvikuru, hunosvika makumi kana kunyange mazana ezviuru zvemaawa, hunopfuura zvakanyanya machubhu e microwave echinyakare.
4. Kuchena kwespectrum uye kugadzikana kwefrequency: Kunyanya kune masosi e-solid-state anoshandisa tekinoroji ye-phase-locked loop (PLL), anogona kugadzira masaini e-microwave akachena uye akasimba ane ruzha rwe-phase rushoma.
5. Kukurumidza kugadzirisa uye kudzora kunochinjika: Kubuda kwefrequency, phase, uye amplitude zvinogona kuchinjwa nekukurumidza uye nemazvo kuburikidza nevoltage (voltage controlled oscillator VCO) kana masaini edhijitari, zvichiita kuti zvive nyore kuwana modulation yakaoma uye agility.
6. Kudzivirira kuvhunduka nekudedera zvakanaka: Nechimiro chakasimba chose, hapana magoko egirazi asina kusimba kana filaments, zvichiita kuti ive nyore kuchinjika kumamiriro ezvinhu akaomarara emakanika.

Kushandiswa:

1. Radar core yemazuva ano: Inoshandiswa zvakanyanya mu automotive millimeter wave radar, military phased array radar, nezvimwewo, kuti ionekwe nemazvo uye ikurumidze kuskena.
2. Nheyo yekutaurirana isina waya: Ndiyo chikamu chakakosha chezviteshi zve5G/6G, kutaurirana kwesatellite, uye michina yekutumira ma microwave, ine basa rekugadzira masaini ekutakura ane ma frequency akakwira.
3. Kuyedza nekuyera nemazvo: Senzira yekuratidza chiratidzo, ndiyo "moyo" wezvishandiso zvepamusoro-soro zvakaita se spectrum analyzers uye network analyzers, zvichiita kuti bvunzo dzive dzakarurama.
4. Zvishandiso zvemaindasitiri nesainzi: Zvinoshandiswa pakudziisa, kuomesa, pamwe chete nezvinokurumidzisa zvidimbu uye kudziisa plasma yemidziyo yekubatanidza nuclear muminda yekutsvagisa kwesainzi.
5. Kuchengetedzwa uye hondo yemagetsi: Inoshandiswa pakugadzira mifananidzo yevanhu uye michina yekudzivirira muhondo yemagetsi, ichigadzira zviratidzo zvakaoma kuti zvipindire.

Qualwaveinopa jenareta yemagetsi ye microwave yakasimba ine frequency ye 2.45GHz. Zvigadzirwa zvedu zvinoshandiswa zvakanyanya munzvimbo dzakawanda.
