Ikoranabuhanga rya Sichuan Keenlion Microwave Yashinzwe mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ni iya mbere mu gukora ibice bya Passive Mircrowave i Sichuan Chengdu, mu Bushinwa.

Dutanga imikorere-yimikorere ya mirrowave hamwe na serivisi zijyanye na porogaramu ya microwave murugo no mumahanga. Ibicuruzwa birahenze cyane, harimo gutandukanya imbaraga zitandukanye, guhuza icyerekezo, gushungura, guhuza, duplexers, ibikoresho byabigenewe byabigenewe, kwigunga no kuzenguruka. Ibicuruzwa byacu byateguwe byumwihariko kubidukikije bikabije nubushyuhe. Ibisobanuro birashobora gutegurwa ukurikije ibyo umukiriya asabwa kandi birakurikizwa kumurongo wose usanzwe kandi uzwi cyane hamwe numuyoboro utandukanye kuva DC kugeza 50GHz.

Muyunguruzi

Akayunguruzo gashobora gushungura neza inshuro yumurongo wihariye mumurongo wamashanyarazi cyangwa inshuro zitari aho zikurikirana, kubona ibimenyetso byingufu zumurongo wumurongo runaka, cyangwa gukuraho ikimenyetso cyumurongo wihariye.

 

Intangiriro

Akayunguruzo ni igikoresho cyo gutoranya cyemerera ibice byihariye bya signal mu kimenyetso cyo gutambuka, nibindi bice bigize imirongo byegeranye cyane. Ingaruka yo guhitamo ukoresheje akayunguruzo irashobora kuyungurura hanze yurusaku rwivanga cyangwa gukora isesengura ryikurikiranya. Muyandi magambo, byitwa akayunguruzo gashobora gutera igice cyihariye cyikimenyetso mu kimenyetso, kandi gihuza cyane cyangwa gihagarika ibindi bice bigize imirongo. Akayunguruzo ni igikoresho cyungururwa n'umuraba. "Umuhengeri" ni igitekerezo cyagutse cyane cyumubiri, mubijyanye na tekinoroji ya elegitoroniki, "umuraba" ugarukira gusa kubikorwa byo gukuramo agaciro k'ibintu bitandukanye bifatika mugihe runaka. Inzira ihindurwa mugihe cyimikorere ya voltage cyangwa ikigezweho binyuze mubintu bitandukanye byumubiri, cyangwa ibimenyetso. Kubera ko igihe cyo kwihinduranya ari agaciro gahoraho, byitwa ibimenyetso byigihe cyigihe, kandi mubisanzwe byitwa ibimenyetso bisa.

Gushungura ni igitekerezo cyingenzi mugutunganya ibimenyetso, kandi umurimo wo kuyungurura uruziga mumashanyarazi ya DC ni ukugabanya ibice bigize AC mumashanyarazi ya DC bishoboka, kugumana ibikoresho byayo bya DC, kugirango coeffisente ya voltage ripple igabanuke, imivumba ihinduka Smooth.

Tibipimo nyamukuru:

Umuyoboro wa Centre: Frequency f0 ya filteri ya passband, mubisanzwe fata f0 = (f1 + f2) / 2, f1, f2 nkumuyoboro wa bande cyangwa bande irwanya akayunguruzo ibumoso, iburyo butandukanye na 1 dB cyangwa 3DB yumurongo wumurongo. Akayunguruzo kagufi gakunze kubara umurongo wa passband hamwe numwanya muto wo gutakaza kwinjiza.

Igihe ntarengwa: Yerekeza ku nzira igana inzira ya passband ya pass pass yo muyunguruzi hamwe na bande ya pass yo hejuru ya filteri. Mubisanzwe bisobanurwa muburyo bwo gutakaza igihombo cya 1 dB cyangwa 3DB. Ikirangantego cyerekeranye no gutakaza ni: pass yo hasi ishingiye ku kwinjiza DC, na Qualcomm ishingiye kumurongo uhagije wo gutambuka wa parasitike.

Umuyoboro mugari: bivuga ubugari bwa spran isabwa kunyura, BW = (F2-F1). F1, F2 ishingiye ku gihombo cyo kwinjiza kuri centre yumurongo F0.

Igihombo cyo gushiramo: Bitewe no kwinjiza akayunguruzo mu kirere cyerekana ibimenyetso byumwimerere mu muzunguruko, igihombo kiri hagati cyangwa inshuro zo guhagarika, nkibisabwa kugira igihombo cyose kugirango ushimangire.

Ripple: Yerekeza kuri 1DB cyangwa 3DB yumurongo wa interineti (gukata inshuro), igihombo cyinjiza gihindura impinga yumurongo kuri gihombo bivuze umurongo.

Imihindagurikire y'imbere: Gutakaza kwinjiza muri bande hamwe na bande itandukanye. Guhindagurika kwitsinda muri 1db umurongo wa 1db.

Muri bande ihagaze: Gupima niba ikimenyetso muri passband muyungurura ari cyiza guhuza ihererekanyabubasha. Umukino mwiza VSWR = 1: 1, VSWR irarenze 1 mugihe idahuye. Kubyungurura nyabyo, umurongo wuzuza VSWR uri munsi ya 1.5: 1 mubusanzwe uri munsi ya BW3DB, ibara igipimo cya BW3DB hamwe na filteri yo kuyungurura no gushiramo igihombo.

Gutakaza umugozi: Umubare wa decibels (DB) ibipimo byibyapa byinjira byinjira nimbaraga zigaragazwa bingana na 20 Log 10ρ, ρ ni coefficient de voltage. Igihombo cyo kugaruka ni ntarengwa iyo imbaraga zinjiza zinjijwe nicyambu.

Imyororokere yo guhagarika umurongo: ikintu cyingenzi cyerekana ubuziranenge bwiyungurura imikorere. Hejuru yikigereranyo, nibyiza byo guhagarika ibimenyetso byo guhagarika ibimenyetso. Mubusanzwe hariho ubwoko bubiri bwibyifuzo: uburyo bwo guhagarika umubare DB ibuza umurongo watanzwe wambukiranya fs, uburyo bwo kubara ni FS igabanuka; ikindi kimenyetso cyerekana icyifuzo cyo kuyungurura ibimenyetso hamwe nuburyo bwiza bwurukiramende - Coefficient yurukiramende (KXDB irenze 1), KXDB = BWXDB / BW3DB, (X irashobora kuba 40dB, 30dB, 20DB, nibindi). Kurenza urukiramende, niko urukiramende ruri hejuru - ni ukuvuga, wegereye agaciro keza 1, kandi ingorane zo gukora umusaruro birumvikana ko ari nini.

Gutinda: Ikimenyetso cyerekana igihe gikenewe kugirango ikimenyetso cyohereze icyiciro cya fonction diagonal frequency, ni ukuvuga TD = DF / DV.

Mu itsinda rya bande umurongo: Iki kimenyetso kiranga akayunguruzo ni icyiciro cyo kugoreka ibimenyetso byanyujijwe muri passband. Akayunguruzo kateguwe n'umurongo wo gusubiza ibikorwa bifite icyiciro cyiza.

Ibyiciro byingenzi

Igabanyijemo igereranya na filteri ya sisitemu ukurikije ibimenyetso bitunganywa.

Ibice byanyuze mubice byayunguruzo bigabanijwemo inzira ntoya, inzira ndende, umurongo, hamwe na byose-byungurura.

Akayunguruzo gato:yemerera ibice bike cyangwa DC mubice byerekana ko byanyuze, guhagarika ibice byinshi byumuvuduko cyangwa kwivanga n urusaku;

Akayunguruzo keza cyane: yemerera ibice byinshi byumurongo mubimenyetso byanyuze, guhagarika imirongo mike cyangwa ibice bya DC;

Bande Pass Pass Muyunguruzi: Yemerera ibimenyetso gutambuka, ibimenyetso byahagaritswe, kwivanga, n urusaku munsi cyangwa hejuru yumurongo;

Akayunguruzo: Ihagarika ibimenyetso mubice bimwe byinshyi byemerera ibimenyetso bitari bande, bizwi kandi nkayunguruzo.

Byose-byungurura: Iyungurura ryuzuye-bisobanura ko amplitude yikimenyetso itazahinduka murwego rwuzuye, ni ukuvuga, inyungu ya amplitude yurwego rwuzuye ihwanye na 1. Rusange byose-byungurujwe byungururwa bikoreshwa mugice cyiciro, ni ukuvuga icyiciro cyo kwinjiza ibimenyetso bihinduka, kandi icyiza nuko ihinduka ryicyiciro rihwanye ninshuro, ibyo bikaba bihwanye na sisitemu yo gutinda.

Ibice byombi byakoreshejwe byombi ni pasiporo kandi ikora muyunguruzi.

Ukurikije ishyirwa muyungurura, muri rusange igabanijwemo isahani yo kuyungurura.

Ku kibaho, shyira ku kibaho, nka PLB, akayunguruzo ka JLB. Ibyiza byiyi filteri nubukungu, kandi ibibi ni uko gushungura inshuro nyinshi atari byiza. Impamvu nyamukuru yacyo ni:

1. Nta bwigunge buri hagati yinjiza nibisohoka muyungurura, bikunda guhuzwa;

2, gushingira kubutaka bwa filteri ntabwo ari hasi cyane, bigabanya intege nke za bypass ingaruka;

3, igice cyo guhuza hagati ya filteri na chassis bizabyara ingaruka ebyiri mbi: imwe ni interineti ya electronique ya magnetiki yumwanya wimbere wa chassis, ihita yinjizwa kumurongo, kumurongo, hanyuma ikayungurura akayunguruzo hakoreshejwe imirasire yumurongo. Kunanirwa; ikindi ni uko interineti yo hanze yungururwa na filteri iyungurura ku kibaho, cyangwa imirasire ikorwa mu buryo butaziguye cyangwa butaziguye ku muzunguruko ku kibaho cy’umuzunguruko, bikavamo ibibazo byo kumva;

Akayunguruzo k'ibisahani, akayunguruzo gahuza hamwe nibindi bikoresho byungurura byashyizwe kumurongo wicyuma cya chassis ikingira. Kubera ko yashyizwe mu buryo butaziguye ku cyuma, ibyinjira n’ibisohoka muyungurura byitaruye rwose, ubutaka burahagaze neza, kandi kwivanga kuri kabili byungururwa hejuru yicyambu cya chassis, bityo ingaruka zo kuyungurura nibyiza cyane.

Akayunguruzo

Akayunguruzo ka pasiporo ni akayunguruzo gakoresha rezistor, reaction, hamwe na capacitor. Iyo rezanse yumurongo, agaciro k'umuzunguruko agaciro ni gake, kandi inzitizi zumuzunguruko nini, agaciro k'ibice bigize uruzinduko bihindurwamo ibintu biranga inshuro nyinshi, kandi ihuriro rishobora gushungura; mugihe inshuro nyinshi zihuza Inzira zuzuzanya zakozwe, noneho ibintu bihuye nibisanzwe bihuza bishobora gushungura, no kuyungurura umubare nyamukuru uhuza (3, 5, 7) bigerwaho no kurenga inzitizi nke. Ihame nyamukuru ni ryumubare utandukanye wubwuzuzanye, gushushanya inshuro zingana ni nto, kugera ku ngaruka zo kugabana imiyoboro ihuje, itanga inzira yo kunyuramo kugirango ihindurwe neza.

Akayunguruzo ka pasiporo gashobora kugabanywa muyunguruzi ya capacitif, amashanyarazi yumuriro w'amashanyarazi, L-RC muyunguruzi, π-shusho ya RC iyungurura, imirongo myinshi ya RC iyungurura, hamwe na π ifite LC yo kuyungurura. Kanda kugirango ukore mumurongo umwe wo guhuza, guhuza ibice bibiri, hamwe na pass yo hejuru. Akayunguruzo ka pasiporo gafite ibyiza bikurikira: imiterere iroroshye, ikiguzi cyishoramari ni gito, kandi ibintu bifatika muri sisitemu birashobora kwishyura ibintu byingufu muri sisitemu. Itezimbere imbaraga za gride; imikorere ihamye ni ndende, kubungabunga biroroshye, gukura tekinike, nibindi birakoreshwa cyane. Hariho ibintu byinshi byerekana amakosa ya filozofiya ya pasiporo: ingaruka zumurongo wa gride ya gride, sisitemu impedance agaciro numubare munini wumurongo wa resonant akenshi uhinduka nkibikorwa byakazi; akayunguruzo gahuza ni kagufi, gusa umubare wingenzi wibihe byingenzi ushobora gushungura gusa Harmonics, cyangwa kubera ibisigara bisa, byongerera imbaraga; guhuza hagati yo kuyungurura nindishyi zidasanzwe hamwe nigitutu kigenga; nkibiriho byanyuze muyungurura, birashobora gutera imikorere irenze ibikoresho; Ibikoreshwa ni binini cyane, uburemere nubunini ni binini; imikorere ihamye ni mibi. Kubwibyo, ibikorwa byungurura nibikorwa byiza nibindi byinshi.

Turashobora kandi gutunganya ibice bya rf bikurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
