I-Sichuan Keenlion Microwave Technology——Imishini yokwenziwa

I-Sichuan Keenlion Microwave Technology Yasungulwa ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye zePassive Mircrowave eSichuan Chengdu, eChina.
Sihlinzeka ngezingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezicelo ze-microwave ekhaya naphesheya. Imikhiqizo ibiza kakhulu, kufaka phakathi isihlukanisi samandla ahlukahlukene, ama-couplers aqondisayo, izihlungi, izihlanganisi, ama-duplexer, izakhi ezenziwe ngokwezifiso zokungenzi lutho, ama-isolator nama-circulator. Imikhiqizo yethu iklanyelwe ngokukhethekile izindawo ezihlukahlukene eziyingozi kanye namazinga okushisa. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi iyasebenza kuwo wonke amabhendi amafrikhwensi ajwayelekile nadumile anomkhawulokudonsa ohlukahlukene ukusuka ku-DC kuye ku-50GHz.

Imishini yokwenziwa
Imishini engenzi lutho iyisigaba esibalulekile semishini ye-microwave ne-RF, edlala indima ebaluleke kakhulu kubuchwepheshe be-microwave. Izingxenye ze-Passive ikakhulukazi zifaka ama-resistors, ama-capacitor, ama-inductors, iziguquli, ama-gradient, amanethiwekhi afanayo, ama-resonators, izihlungi, izihlanganisi namaswishi.

Uhlobo lwedivayisi
Isingeniso sezinhlobo zezilwane
Izingxenye ze-Passive ikakhulukazi zifaka ama-resistors, ama-capacitor, ama-inductors, iziguquli, ama-gradient, amanethiwekhi afanayo, ama-resonators, izihlungi, izihlanganisi namaswishi. Ingxenye ye-elekthronikhi engabonisa izici zayo ngaphandle kokunikezwa kwamandla angaphandle. Izingxenye ze-Passive ikakhulukazi zingamadivayisi aphikisayo, ama-inductive kanye nama-capacitive. Isici sabo esivamile ukuthi bangasebenza uma kukhona isignali ngaphandle kokwengeza amandla kumjikelezo.

isiphikisa
Lapho i-current idlula ku-conductor, indawo lapho ukumelana kwangaphakathi kwe-conductor kuvimbela okwamanje kubizwa ngokuthi ukumelana. Izingxenye ezidlala indima yokuvimbela okwamanje kumjikelezo zibizwa ngokuthi ama-resistors, abizwa ngokuthi ama-resistors okwesikhashana. Inhloso eyinhloko ye-resistor ukunciphisa i-voltage, ukuhlukanisa i-voltage noma i-shunt. Isetshenziswa njengomthwalo, impendulo, ukuhlanganisa, ukuhlukaniswa, njll. kwezinye izifunda ezikhethekile.
Uphawu lokumelana kumdwebo wesifunda uhlamvu R. Iyunithi evamile yokumelana i-Ohm, erekhodwa ngokuthi Ω. Okuvame ukusetshenziswa yi-kiloohm KΩ kanye ne-megaohm mΩ.
I-IKΩ=1000Ω 1MΩ=1000KΩ

i-capacitor
I-Capacitor futhi ingenye yezingxenye ezivame kakhulu kumasekethe kagesi. Kuyingxenye yokugcina amandla kagesi. I-capacitor yakhiwe ngama-conductor amabili anosayizi ofanayo kanye nekhwalithi ehlanganiswe nongqimba lwe-insulating medium. Uma i-voltage isetshenziswa kuzo zombili iziphetho ze-capacitor, inkokhelo kagesi igcinwa ku-capacitor. Uma ingekho i-voltage, inqobo nje uma kunesekhethi evaliwe, izokhipha amandla kagesi. I-capacitor ivimbela i-DC ukuthi ingadluli kumjikelezo futhi ivumela i-AC ukuthi idlule. Uma iphakeme imvamisa ye-AC, inamandla okudlula. Ngakho-ke, ama-capacitor avame ukusetshenziswa kumasekethe okuhlanganisa, ukuhlunga kwe-bypass, impendulo, isikhathi kanye ne-oscillation.
Ikhodi yezinhlamvu ye-capacitor ithi C. Iyunithi ye-capacitance ithi farad (irekhodwe ngokuthi f), evame ukusetshenziswa μF (indlela encane), PF (okungukuthi μμF. Indlela ye-Pico).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Izici ze-capacitance kusekethe azikho emthethweni. I-impedance to current ibizwa ngokuthi i-capacitive reactance. Ukusabela kwe-Capacitive kuqhathaniswa ngokuphambene namandla kanye nemvamisa yesignali.

Inductor
Njenge-capacitance, i-inductance nayo iyingxenye yokugcina amandla. Ama-inductors ngokuvamile enziwa ngamakhoyili. Lapho i-voltage ye-AC isetshenziswa kuzo zombili iziphetho zekhoyili, amandla e-electromotive akhangisiwe akhiqizwa kukhoyili, okuvimbela ukuguquguquka kwamanje okudlula kukhoyili. Lesi sithiyo sibizwa ngokuthi ukumelana ne-inductive. Ukusabela kwe-inductive kuhambisana ngokuqondile ne-inductance kanye nemvamisa yesiginali. Ayivimbeli i-DC yamanje (kungakhathaliseki ukuthi i-DC imelana kanjani nekhoyili). Ngakho-ke, indima ye-inductance kumasekethe e-elekthronikhi yilena: ukuvinjwa kwamanje, ukuguqulwa kwe-voltage, ukuhlanganisa nokumatanisa ne-capacitance yokulungisa, ukuhlunga, ukukhetha imvamisa, ukuhlukaniswa kwamafrikhwensi, njll.
Ikhodi ye-inductance kusekethe ithi L. Iyunithi ye-inductance ngu-Henry (erekhodwe njengo-H), futhi evame ukusetshenziswa yi-milliheng (MH) ne-micro Heng (μH).
1H=1000mH 1mH=1000μH
I-inductance iyisici esijwayelekile sokungeniswa kwe-electromagnetic kanye nokuguqulwa kwe-electromagnetic. Isicelo esivame kakhulu i-transformer.

Isiqondiso sentuthuko
1. I-modularization ehlanganisiwe iyinkambo yokuthuthukiswa yesikhathi esizayo yezingxenye ze-passive. Imojula yokuhlanganisa inikeza ikhono lokuhlanganisa izingxenye ezisebenzayo noma amamojula kanye nezingxenye ze-passive, futhi ihlangabezana nezidingo zokunciphisa amamojula kanye nezindleko eziphansi ngesikhathi esifanayo. Izindlela eziyinhloko zihlanganisa: ukushisa okuphansi kokushisa okuphansi kobuchwepheshe be-ceramic (LTCC), ubuchwepheshe befilimu encane, ubuchwepheshe be-silicon wafer semiconductor, ubuchwepheshe bebhodi lesifunda se-multilayer, njll.
2. I-Miniaturization. Ukuphishekela ukwenza i-miniaturization kanye ne-lightweight embonini engenazintambo kudinga amadivaysi angenzi lutho ukuthi athuthuke endaweni encane. I-Micro electro mechanical system (MEMS) isetshenziswa ngokuyinhloko ukwenza izingxenye ze-RF zibe zincane, izindleko eziphansi, ezinamandla kakhudlwana futhi ezilungele ukuhlanganiswa.
3. Umphumela we-encapsulation. Uma kuqhathaniswa nezingxenye ezisetshenziswayo ezisetshenziswayo ezisetshenziswa kakhulu, ukuhlanganiswa kwezingxenye ephaketheni kungathuthukisa ngempumelelo ukwethembeka kwesistimu, kufinyeze indlela yokuqhuba, kunciphise imiphumela ye-parasitic, kunciphise izindleko futhi kunciphise ubukhulu bamadivayisi.

Umehluko phakathi kwezingxenye ezisebenzayo nezingenzi lutho
Amadivayisi angasebenzi angamadivayisi angabonisa izici zawo zangaphandle ngokuzimela ngaphandle kokuba khona kwamandla angaphandle (DC noma AC). Ngaphandle kwalokho, kukhona amadivaysi asebenzayo. Okubizwa ngokuthi "isici sangaphandle" ukuchaza inani elithile lobudlelwano bedivayisi, nakuba i-voltage noma yamanje, inkambu kagesi noma indawo kazibuthe, ingcindezi noma isivinini kanye nezinye izinto eziningi kusetshenziswa ukuchaza ubudlelwano bayo.

Singakwazi futhi ukwenza ngokwezifiso izingxenye ze-rf passive ngokuya ngezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
