Jenereithara ea motlakase ea microwave e tiileng ke sesebelisoa sa elektroniki se sebelisang lisebelisoa tsa semiconductor tse kang li-diode tsa Gunn, li-diode tsa IMPATT, li-transistors tsa FET, li-transistors tsa HEMT, jj. ho hlahisa maqhubu a motlakase a maqhubu a microwave (hangata a bua ka 300MHz ~ 300GHz).

E fapane ka ho feletseng le mehloli ea microwave ea setso ea "lisebelisoa tsa motlakase tsa vacuum" tse kang li-magnetron, li-tube tsa maqhubu a tsamaeang, le li-klystrons. Lisebelisoa tsa setso li itšetlehile ka motsamao oa lielektrone tse lokolohileng ka har'a vacuum ho hlahisa li-microwave, ha lijenereithara tsa matla a microwave tsa boemo bo tiileng li itšetlehile ka botlalo ka litšobotsi tsa thepa e tiileng ea semiconductor, e leng se hlahisang ho sisinyeha ka liphetoho tsa motsamao le boemo ba matla ba lielektrone ka har'a sebopeho sa lattice ea semiconductor.

Litšobotsi:

1. Boholo bo bonyenyane le boima bo bobebe: Karolo e ka sehloohong ke chip ea semiconductor, e sa hlokeng lipeipi tsa vacuum kapa lisebelisoa tsa motlakase tse nang le motlakase o phahameng, e leng se etsang hore sesebelisoa sohle se be se senyenyane haholo 'me se be bonolo ho se kopanya le litsamaiso tsa sejoale-joale tsa elektroniki.
2. Motlakase o tlase o sebetsang le polokeho e phahameng: Hangata ho hlokahala li-volt tse 'maloa feela ho isa ho tse mashome tsa motlakase o tlase oa DC, athe lisebelisoa tsa motlakase tse hloekisang hangata li hloka li-volt tse likete tsa motlakase o phahameng. Sena se etsa hore e bolokehe haholoanyane 'me moralo oa motlakase o be bonolo.
3. Nako e telele ea bophelo le ts'epo e phahameng: Ntle le lintho tse sebelisoang tse kang li-filament tsa cathode, nako ea thuto ea lisebelisoa tsa semiconductor e telele haholo, e fihla lihora tse mashome kapa esita le makholo a likete, e feta li-tube tsa microwave tsa setso haholo.
4. Bohloeki ba spectrum le botsitso ba maqhubu: Haholo-holo bakeng sa mehloli ea boemo bo tiileng e sebelisang theknoloji ea phase-locked loop (PLL), li ka hlahisa matšoao a microwave a hloekileng haholo le a tsitsitseng haholo ka lerata le tlase la phase.
5. Lebelo la ho lokisa ka potlako le taolo e tenyetsehang: Maqhubu a tlhahiso, mohato le boholo ba motlakase li ka fetoloa kapele haholo le ka nepo ka motlakase (voltage controlled oscillator VCO) kapa matšoao a dijithale, e leng se etsang hore ho be bonolo ho fihlella modulation e rarahaneng le bokgoni ba ho sebetsa.
6. Ho hanyetsa ho thothomela le ho thothomela hantle: Ka sebopeho se tiileng ka botlalo, ha ho na likhetla tsa khalase tse senyehang habonolo kapa likhoele, e leng se etsang hore e ikamahanye le maemo a thata a mechini.

Kopo:

1. Sehlohlolo sa radar sa sejoale-joale: Se sebelisoa haholo ho radar ea maqhubu a millimeter ea likoloi, radar ea mekhahlelo ea sesole, jj., ho fihlella ho fumanoa ka nepo le ho hlahlojoa ha mahlaseli ka potlako.
2. Motheo oa puisano o se nang mohala: Ke karolo ea bohlokoa ea liteishene tsa motheo tsa 5G/6G, puisano ea sathelaete, le lisebelisoa tsa phetisetso ea microwave, tse ikarabellang bakeng sa ho hlahisa matšoao a sephethephethe a maqhubu a phahameng.
3. Teko le tekanyo e nepahetseng: Jwalo ka mohlodi wa letshwao, ke "pelo" ya disebediswa tsa maemo a hodimo tse kang di-spectrum analyzer le di-network analyzer, tse netefatsang ho nepahala ha teko.
4. Lisebelisoa tsa indasteri le tsa saense: Li sebelisetsoa ho futhumatsa, ho omisa indasteri, hammoho le li-accelerator tsa likaroloana le ho futhumatsa plasma bakeng sa lisebelisoa tsa ho kopanya nyutlelie masimong a lipatlisiso tsa saense.
5. Tšireletso le ntoa ea elektroniki: E sebelisoa bakeng sa litsamaiso tsa litšoantšo tsa ts'ireletso ea batho le mechini ea ho thibela likhohlano ntoeng ea elektroniki, e hlahisang matšoao a rarahaneng ho kenya tšebetsong tšitiso.

Qualwavee fana ka jenereithara ea motlakase ea microwave e tiileng e nang le maqhubu a 2.45GHz. Lihlahisoa tsa rona li sebelisoa haholo libakeng tse ngata.
