XHUMANA MANJE

Ijeneretha yamandla e-solid-state microwave iyinsiza kagesi esebenzisa amadivaysi esemiconductor afana nama-Gunn diode, ama-IMPATT diode, ama-FET transistors, ama-HEMT transistors, njll. ukuze kukhiqizwe amaza kagesi kagesi e-microwave (ngokuvamile ebhekisela ku-300MHz~300GHz).

Ihluke kakhulu emithonjeni yendabuko ye- "vacuum vacuum kagesi" yendabuko efana nozibuthe, amashubhu ajikelezayo, nama-klystrons. Amadivayisi avamile ancike ekunyakazeni kwama-electron amahhala ku-vacuum ukuze akhiqize ama-microwave, kuyilapho amajeneretha wamandla e-microwave embuso athembele ngokuphelele ezicini zezinto eziqinile ze-semiconductor, akhiqiza ama-oscillation ngokunyakaza nezinga lamandla lama-electron ngaphakathi kwesakhiwo se-semiconductor lattice.

Izici:

1. Usayizi omncane nesisindo esilula: Ingqikithi iyi-chip ye-semiconductor, engadingi amashubhu e-vacuum noma amandla kagesi aphezulu, okwenza yonke idivayisi iminyene kakhulu futhi kube lula ukuhlanganisa izinhlelo zikagesi zesimanje.
2. Amandla kagesi aphansi okusebenza nokuphepha okuphezulu: Ngokuvamile ama-volts ambalwa kuphela kuya kumashumi amavolthi wamandla kagesi aphansi e-DC ayadingeka, kuyilapho izisetshenziswa zikagesi zevacuum ngokuvamile zidinga izinkulungwane zamavolthi kagesi aphezulu. Lokhu kuyenza iphephe kakhudlwana futhi nomklamo wamandla ube lula.
3. Ukuphila okude nokuthembeka okuphezulu: Ngaphandle kwezinto ezisetshenziswayo ezifana ne-cathode filaments, isikhathi sethiyori se-semiconductor side kakhulu, sifinyelela amashumi noma amakhulu ezinkulungwane zamahora, adlula kude amashubhu e-microwave endabuko.
4. I-Spectrum pureness kanye nokuzinza kwe-frequency: Ikakhulukazi emithonjeni ye-solid-state esebenzisa ubuchwepheshe be-phase-locked loop (PLL), ingakwazi ukukhiqiza amasiginali we-microwave ahlanzekile kakhulu futhi azinze kakhulu ngomsindo wesigaba esiphansi.
5. Isivinini sokushuna esisheshayo nokulawula okuguquguqukayo: Imvamisa yokuphuma, isigaba, kanye ne-amplitude ingashintshwa ngokushesha futhi ngokunembile nge-voltage (i-voltage elawulwa i-oscillator VCO) noma amasignali edijithali, okwenza kube lula ukufeza ukuguquguquka okuyinkimbinkimbi kanye nobubha.
6. Ukushaqeka okuhle nokumelana nokudlidliza: Ngaso sonke isimo sombuso esiqinile, awekho amagobolondo ezingilazi ezintekenteke noma imicu, okuyenza ivumelane nezimo zemishini ezinonya.

Isicelo:

1. I-radar core yesimanje: Isetshenziswa kakhulu ku-radar yamagagasi emilimitha yezimoto, i-radar yezigaba zamasosha, njll., ukuze kuzuzwe ukutholwa okunembayo kanye nokuskena kwe-beam okusheshayo.
2. Isisekelo sokuxhumana okungenantambo: Kuyingxenye ebalulekile yeziteshi eziyisisekelo ze-5G/6G, ukuxhumana ngesathelayithi, kanye nemishini yokudlulisela i-microwave, enesibopho sokukhiqiza amasignali enkampani yenethiwekhi ye-high-frequency.
3. Ukuhlola ukunemba nokulinganisa: Njengomthombo wesignali, "inhliziyo" yamathuluzi asezingeni eliphezulu njengabahlaziyi be-spectrum nabahlaziyi benethiwekhi, okuqinisekisa ukunemba kokuhlola.
4. Amathuluzi ezimbonini nawesayensi: Asetshenziselwa ukushisisa izimboni, ukomisa, kanye nama-accelerator ezinhlayiyana kanye nokushisisa i-plasma kumishini yokuhlanganisa yenuzi emikhakheni yocwaningo lwesayensi.
5. Ukuphepha kanye nempi ye-elekthronikhi: Isetshenziselwa amasistimu wokucabanga ngokuvikeleka kwabantu kanye nemishini yokuhlanganisa impi ye-elekthronikhi, ekhiqiza amasignali ayinkimbinkimbi ukuze kusetshenziswe ukuphazamiseka.

Qualwaveinikeza ijeneretha yamandla e-microwave yesifunda esiqinile enefrikhwensi engu-2.45GHz. Imikhiqizo yethu isetshenziswa kabanzi ezindaweni eziningi.
