Ubuchwepheshe be-Microwave be-Sichuan Keenlion——Amadivayisi angasebenzi

Ubuchwepheshe be-Microwave beSichuan Keenlion Obusungulwe ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye ze-Passive Mircrowave eSichuan Chengdu, eShayina.
Sinikeza izingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezinhlelo zokusebenza ze-microwave ekhaya nakwamanye amazwe. Imikhiqizo ishibhile, kufaka phakathi i-power divider ehlukahlukene, ama-directional couplers, ama-filters, ama-combiners, ama-duplexers, izingxenye ezingasebenzi ezenziwe ngokwezifiso, ama-isolators nama-circulator. Imikhiqizo yethu yenzelwe ngokukhethekile izindawo ezahlukene kanye namazinga okushisa aphezulu. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi isebenza kuwo wonke ama-frequency band ajwayelekile nathandwayo anama-bandwidth ahlukahlukene kusukela ku-DC kuya ku-50GHz.

Amadivayisi angasebenzi
Amadivayisi angasebenzi ayisigaba esibalulekile samadivayisi e-microwave kanye ne-RF, adlala indima ebaluleke kakhulu kubuchwepheshe be-microwave. Izingxenye ezingasebenzi zifaka phakathi ama-resistor, ama-capacitor, ama-inductor, ama-converter, ama-gradients, amanethiwekhi afanayo, ama-resonator, izihlungi, ama-mixer kanye nama-switch.

Uhlobo lwedivayisi
Isingeniso sezinhlobo
Izingxenye ezingasebenzi zifaka phakathi ama-resistor, ama-capacitor, ama-inductor, ama-converter, ama-gradients, amanethiwekhi afanayo, ama-resonator, ama-filters, ama-mixer nama-switch. Ingxenye ye-elekthronikhi engabonisa izici zayo ngaphandle kokunikezwa kwamandla kwangaphandle. Izingxenye ezingasebenzi ngokuyinhloko zingamadivayisi avimbelayo, avuselelayo kanye navikelayo. Isici sazo esivamile ukuthi zingasebenza uma kunesignali ngaphandle kokwengeza amandla kusekethe.

isithambisi
Uma ugesi udlula kumqhubi, isici esivimbela ukumelana kwangaphakathi komqhubi ugesi kubizwa ngokuthi ukumelana. Izingxenye ezidlala indima yokuvimba ugesi kumjikelezo zibizwa ngokuthi ama-resistors, abizwa ngokuthi ama-resistors ngamafuphi. Inhloso eyinhloko ye-resistor ukunciphisa ugesi, ukuhlukanisa ugesi noma i-shunt. Isetshenziswa njengomthwalo, impendulo, ukuxhuma, ukuhlukaniswa, njll. kwezinye izifunda ezikhethekile.
Uphawu lokumelana kumdwebo wesekethe luhlamvu u-R. Iyunithi ejwayelekile yokumelana yi-Ohm, eqoshwe njenge-Ω. Okuvame ukusetshenziswa yi-kiloohm KΩ kanye ne-megaohm mΩ.
IKΩ=1000Ω 1MΩ=1000KΩ

i-capacitor
I-Capacitor ingenye yezingxenye ezivame kakhulu kumasekethe kagesi. Iyingxenye yokugcina amandla kagesi. I-capacitor yakhiwe ngama-conductor amabili anobukhulu obufanayo kanye nekhwalithi efanayo ahlanganiswe nesendlalelo se-insulating medium. Uma i-voltage isetshenziswa kuzo zombili izinhlangothi ze-capacitor, ishaja kagesi igcinwa ku-capacitor. Uma ingekho i-voltage, inqobo nje uma kunesekethe evaliwe, izokhipha amandla kagesi. I-capacitor ivimbela i-DC ukuthi idlule kusekethe futhi ivumela i-AC ukuthi idlule. Uma imvamisa ye-AC iphakeme, ikhono lokudlulisa liqina kakhulu. Ngakho-ke, ama-capacitor avame ukusetshenziswa kumasekethe okuhlanganisa, ukuhlunga i-bypass, impendulo, isikhathi kanye nokunyakaza.
Ikhodi yohlamvu lwe-capacitor ingu-C. Iyunithi ye-capacitance i-farad (iqoshwe njengo-f), evame ukusetshenziswa njenge-μF (indlela encane), i-PF (okungukuthi i-μμF. Indlela ye-Pico).
1F=1000000μF=10^6μF=10^12PF 1μF=1000000PF
Izici ze-capacitance kusekethe aziqondile. I-impedance ku-current ibizwa ngokuthi i-capacitive reactance. I-capacitive reactance ilingana ngokuphambene ne-capacitance kanye nemvamisa yesignali.

I-Inductor
Njenge-capacitance, i-inductance nayo iyisici sokugcina amandla. Ama-inductor ngokuvamile enziwa ngama-coil. Uma i-AC voltage isetshenziswa kuzo zombili izinhlangothi ze-coil, amandla e-electromotive akhiqizwayo akhiqizwa ku-coil, okuvimbela ukudlula kogesi ku-coil ukuthi kushintshe. Lokhu kuvimbela kubizwa ngokuthi ukumelana kokungenisa. I-inductive reactance ilingana ngqo ne-inductance kanye nemvamisa yesignali. Ayivimbeli ugesi we-DC (kungakhathaliseki ukumelana kwe-DC kwe-coil). Ngakho-ke, indima ye-inductance kumasekethe kagesi yile: ukuvimba ugesi, ukuguqulwa kwe-voltage, ukuxhumanisa kanye nokulinganisa ne-capacitance yokulungisa, ukuhlunga, ukukhetha imvamisa, ukuhlukaniswa kwemvamisa, njll.
Ikhodi ye-inductance kusekethe yi-L. Iyunithi ye-inductance nguHenry (eqoshwe njengo-H), kanti evame ukusetshenziswa yi-milliheng (MH) kanye ne-micro Heng (μH).
1H=1000mH 1mH=1000μH
I-inductance iyisici esijwayelekile sokungeniswa kwe-electromagnetic kanye nokuguqulwa kwe-electromagnetic. Ukusetshenziswa okuvame kakhulu yi-transformer.

Isiqondiso sentuthuko
1. I-modularization ehlanganisiwe yindlela yokuthuthukiswa kwesikhathi esizayo kwezingxenye ezingasebenzi. I-module yokuhlanganisa inikeza ikhono lokuhlanganisa izingxenye ezisebenzayo noma amamojula kanye nezingxenye ezingasebenzi, futhi ihlangabezana nezidingo zokunciphisa amamojula kanye nezindleko eziphansi ngesikhathi esisodwa. Izindlela eziyinhloko zifaka: ubuchwepheshe be-ceramic obusebenzisa izinga lokushisa eliphansi (i-LTCC), ubuchwepheshe befilimu encane, ubuchwepheshe be-silicon wafer semiconductor, ubuchwepheshe bebhodi lesekethe elinobubanzi obuningi, njll.
2. Ukwenziwa kube lula. Ukuphishekela ukwenziwa kube lula futhi kube lula embonini engenantambo kudinga amadivayisi angasebenzi ukuze athuthukiswe ngendlela encane. Uhlelo lwe-Micro electro mechanical (MEMS) lusetshenziswa kakhulu ukwenza izingxenye ze-RF zibe zincane, zibe nezindleko eziphansi, zibe namandla futhi zilungele ukuhlanganiswa.
3. Umphumela we-encapsulation. Uma kuqhathaniswa nezingxenye ezivame ukusetshenziswa ezifakwe ebusweni, ukuhlanganiswa kwezingxenye ephaketheni kungathuthukisa ngempumelelo ukuthembeka kohlelo, kufinyeze indlela yokuqhuba, kunciphise imiphumela yezinambuzane, kunciphise izindleko futhi kunciphise usayizi wamadivayisi.

Umehluko phakathi kwezingxenye ezisebenzayo nezingasebenzi
Amadivayisi angasebenzi amadivayisi angabonisa izici zawo zangaphandle ngokuzimela ngaphandle kokuba khona kokunikezwa kwamandla kwangaphandle (i-DC noma i-AC). Ngaphandle kwalokho, kunezisetshenziswa ezisebenzayo. Okubizwa ngokuthi "isici sangaphandle" ukuchaza inani elithile lobudlelwano bedivayisi, yize i-voltage noma i-current, insimu kagesi noma insimu yamagnetic, ingcindezi noma isivinini kanye nezinye izinto zisetshenziswa ukuchaza ubuhlobo bayo.

Singakwazi futhi ukwenza ngezifiso izingxenye ze-rf passive ngokwezidingo zakho. Ungangena ekhasini lokwenza ngezifiso ukuze unikeze imininingwane oyidingayo.
