XHUMANA MANJE

Ijeneretha yamandla e-microwave e-Solid-state iyidivayisi kagesi esebenzisa amadivayisi e-semiconductor njenge-Gunn diodes, i-IMPATT diodes, i-FET transistors, i-HEMT transistors, njll. ukukhiqiza amaza kagesi e-microwave frequency (ngokuvamile abhekisela ku-300MHz ~ 300GHz).

Ihluke kakhulu emithonjeni ye-microwave yendabuko "yamadivayisi kagesi okuhlanza" njenge-magnetrons, amashubhu amagagasi okuhambayo, kanye nama-klystrons. Amadivayisi endabuko athembele ekunyakazeni kwama-electron amahhala ku-vacuum ukuze akhiqize ama-microwave, kuyilapho ama-generator kagesi e-microwave aqinile ethembele ngokuphelele ezicini zezinto eziqinile ze-semiconductor, ekhiqiza ukunyakaza ngokushintsha kwezinga lokunyakaza kanye namandla ama-electron ngaphakathi kwesakhiwo se-lattice se-semiconductor.

Izici:

1. Usayizi omncane nesisindo esilula: Ingaphakathi liyi-chip ye-semiconductor, engadingi amashubhu e-vacuum noma izinsiza zamandla ezinamandla aphezulu, okwenza yonke idivayisi ibe ncane kakhulu futhi kube lula ukuyihlanganisa nezinhlelo zesimanje ze-elekthronikhi.
2. I-voltage yokusebenza ephansi kanye nokuphepha okuphezulu: Ngokuvamile kudingeka ama-volt ambalwa kuya kwamashumi ama-volts wamandla aphansi e-DC, kuyilapho amadivayisi kagesi okuhlanza ngokuvamile edinga izinkulungwane zama-volts wamandla aphezulu. Lokhu kwenza kube okuphephile futhi ukwakheka kwamandla kube lula.
3. Isikhathi eside sokuphila kanye nokuthembeka okuphezulu: Ngaphandle kwezinto ezisetshenziswayo njenge-cathode filaments, isikhathi sokuphila samadivayisi e-semiconductor side kakhulu, sifinyelela emashumini noma ngisho namakhulu ezinkulungwane zamahora, sidlula kakhulu amashubhu e-microwave endabuko.
4. Ubumsulwa be-spectrum kanye nokuqina kwemvamisa: Ikakhulukazi emithonjeni yesimo esiqinile esebenzisa ubuchwepheshe be-phase-locked loop (PLL), ingakhiqiza amasignali e-microwave ahlanzekile kakhulu futhi azinzile kakhulu ngomsindo wesigaba ophansi.
5. Isivinini sokulungisa okusheshayo kanye nokulawula okuguquguqukayo: Imvamisa yokukhipha, isigaba, kanye ne-amplitude kungashintshwa ngokushesha nangokunembile nge-voltage (i-voltage controlled oscillator VCO) noma amasignali edijithali, okwenza kube lula ukufeza ukuguqulwa okuyinkimbinkimbi kanye nokuguquguquka.
6. Ukumelana okuhle nokushaqeka nokudlidliza: Njengoba inesakhiwo esiqinile ngokuphelele, azikho izingqimba zeglasi ezibuthakathaka noma imicu, okwenza kube lula ukuzivumelanisa nezimo ezibucayi zemishini.

Isicelo:

1. I-radar core yesimanje: Isetshenziswa kabanzi kwi-automotive millimeter wave radar, i-military phased array radar, njll., ukuze kutholakale ukutholakala okunembile kanye nokuskena okusheshayo kwe-beam.
2. Isisekelo sokuxhumana okungenantambo: Siyingxenye ebalulekile yeziteshi zesisekelo ze-5G/6G, ukuxhumana kwesathelayithi, kanye nemishini yokudlulisa ama-microwave, enesibopho sokukhiqiza amasignali okuthwala amaza aphezulu.
3. Ukuhlolwa nokulinganisa ngokunemba: Njengomthombo wesignali, "yinhliziyo" yezinsimbi ezisezingeni eliphezulu njengezihlaziyi ze-spectrum kanye nezihlaziyi zenethiwekhi, okuqinisekisa ukunemba kokuhlola.
4. Amathuluzi ezimboni nawesayensi: Asetshenziselwa ukushisa, ukomisa, kanye nezisheshisi zezinhlayiya kanye nokushisa kwe-plasma kwamadivayisi okuhlanganisa i-nuclear emikhakheni yocwaningo lwesayensi.
5. Ukuphepha kanye nempi ye-elekthronikhi: Kusetshenziselwa izinhlelo zokuthwebula izithombe zokuphepha kwabantu kanye nemishini yokujima empini ye-elekthronikhi, okukhiqiza izimpawu eziyinkimbinkimbi zokusebenzisa ukuphazamiseka.

I-Qualwaveinikeza ijeneretha yamandla e-microwave eqinile enemvamisa engu-2.45GHz. Imikhiqizo yethu isetshenziswa kabanzi ezindaweni eziningi.
