NikiAkayunguruzo ka RF?

Akayunguruzo ka radiyo ni igice cyingenzi cyikoranabuhanga ridafite umugozi. Ikoreshwa hamwe na radio yakira kugirango iyungurure andi matsinda adakenewe kandi yakira gusa umurongo ukwiye. Akayunguruzo ka RF kagenewe gukora byoroshye murwego rwumurongo uva hagati yigihe kinini kugeza kuri radiyo ndende cyane (urugero megahertz na gigahertz). Kubera imiterere yakazi, ikoreshwa cyane mumaradiyo, itumanaho ridafite insinga, tereviziyo nibindi bikoresho.

Mubisanzwe, RF nyinshi muyunguruzi igizwe na resonator ihujwe, kandi ibintu byiza birashobora kugena urwego rwo kuyungurura muri RF. Ukurikije porogaramu nubunini bwibikoresho bidafite umugozi, hari ubwoko bwinshi bwo kuyungurura, aribwo filteri ya cavity, filteri yindege, filteri ya electroacoustic, filteri ya dielectric, filteri ya coaxial (idashingiye kumurongo wa coaxial), nibindi.

Ubwoko bwibanze bwa Radio Frequency Akayunguruzo

Akayunguruzo ka RF ni umuzenguruko udasanzwe utanga ibimenyetso nyabyo kunyuramo mugihe ukuraho ibimenyetso udashaka. Kubyerekeranye no kuyungurura topologiya, hari ubwoko bune bwibanze bwa RF muyunguruzi, aribyo, hejuru ya filteri yo hejuru, iyungurura rito, iyungurura ryayunguruzo hamwe na bande ihagarika akayunguruzo

Akayunguruzo gato:

Nkuko izina ribivuga, akayunguruzo gato-kayunguruzo ni akayunguruzo gatuma gusa imirongo mike inyuramo kandi igahuza ibindi bimenyetso byerekana icyarimwe. Iyo ikimenyetso kinyuze kumurongo, kugabanuka kwinshuro kugenwa nibintu byinshi, nka filteri topologiya, imiterere nubuziranenge bwibigize. Mubyongeyeho, akayunguruzo topologiya nayo igena umuvuduko winzibacyuho ya filteri kuva kuri passband kugirango igere kumurongo wanyuma.

Akayunguruzo gato kayunguruzo kaza muburyo butandukanye. Porogaramu nyamukuru yo kuyungurura ni uguhagarika guhuza kwa amplifier ya RF. Iyi mikorere ni ngombwa kuko ifasha kwirinda kwivanga bitari ngombwa biturutse kumirongo itandukanye. Byibanze, pass pass yo kuyungurura ikoreshwa mumajwi ya porogaramu no kuyungurura urusaku ruva hanze. Nyuma yikimenyetso kinini-cyayungurujwe, ibimenyetso byabonetse byabonetse bifite ireme risobanutse.

Akayunguruzo Kurenga:

Bitandukanye na buke yo muyunguruzi, urwego rwo hejuru rwungurura rwemerera gusa ibimenyetso byihuta byo kunyuramo. Mubyukuri, inzira ndende yo kuyungurura hamwe na pass yo muyunguruzi iruzuzanya cyane, kuko byombi muyunguruzi birashobora gukoreshwa hamwe kugirango bibyare umurongo-unyuramo. Igishushanyo mbonera cyo hejuru cyayunguruzo kirayobora kandi gihuza inshuro munsi yumuryango.

Mubisanzwe, inzira ndende yo kuyungurura ikoreshwa muri sisitemu yijwi, unyuzamo imirongo mike yo hasi. Mubyongeyeho, ikoreshwa kandi mugukuraho abavuga rito na bass mubihe byinshi; Iyungurura ryubatswe muburyo bwihariye. Ariko, niba hari umushinga DIY urimo, urwego rwo hejuru rwungurura rushobora guhuzwa byoroshye na sisitemu.

Bande Pass Muyunguruzi:

Akayunguruzo-kayunguruzo ni uruziga rwemerera ibimenyetso kuva kuri radiyo ebyiri zitandukanye kunyuramo no guhuza ibimenyetso bitari murwego rwemewe. Byinshi muri band-pass muyunguruzi yishingikiriza kumasoko yose yo hanze kandi ikoresha ibice bikora, aribyo bizunguruka hamwe na tristoriste. Ubu bwoko bwa filteri bwitwa gukora band-pass muyunguruzi. Kurundi ruhande, bande-pass ya filteri ntabwo ikoresha amashanyarazi yo hanze kandi yishingikiriza cyane kubice bya pasiporo, aribyo inductors na capacator. Muyunguruzi byitwa passiyo band-pass muyunguruzi.

Akayunguruzo ka bande gakoreshwa muburyo butemewe bwo kwakira no kohereza. Igikorwa cyacyo nyamukuru muri transmitter ni ukugabanya umurongo mwinshi wibimenyetso bisohoka kugeza byibuze, kugirango amakuru asabwa ashobora koherezwa kumuvuduko ukenewe. Iyo uwakiriye abigizemo uruhare, bande-pass muyunguruzi yemerera gusa decoding cyangwa kumva umubare ukenewe wa frequence, mugihe uca ibindi bimenyetso bivuye kumurongo udashaka.

Mu ijambo, iyo band-pass ya filteri yateguwe, irashobora kugabanya byoroshye ubwiza bwibimenyetso no kugabanya irushanwa cyangwa kwivanga hagati yibimenyetso.

Itsinda ryanze:

Rimwe na rimwe byitwa guhagarika guhagarika akayunguruzo, guhagarika guhagarika akayunguruzo ni akayunguruzo gatuma imirongo myinshi inyuramo idahindutse. Ariko, ihuza imirongo iri munsi yurwego rwihariye. Imikorere yacyo ihabanye rwose niyindi ya bande-pass filter. Ahanini, imikorere yacyo ni ukunyuza inshuro kuva kuri zeru kugeza kumwanya wambere waciwe. Hagati, itambutsa imirongo yose hejuru ya kabiri yo guca kumurongo. Ariko, iramagana cyangwa ikabuza izindi frequency zose hagati yizi ngingo zombi.

Mu ijambo, akayunguruzo nikintu cyemerera ibimenyetso kunyuramo hifashishijwe passband. Muyandi magambo, guhagarika umurongo muyungurura ni ingingo aho imirongo imwe yangwa nayunguruzo. Byaba ari hejuru cyane, pass yo hasi cyangwa bande pass, icyunguruzo cyiza ni akayunguruzo nta gihombo mumatsinda. Ariko, mubyukuri, nta filteri nziza ihari kuko bande izagira igihombo cyinshyi kandi ntibishoboka kugera kubihagarika bitagira umupaka mugihe umurongo uhagaze.

Kuki Akayunguruzo ka Radio Frequency Akamaro?

Akayunguruzo ka RF gakoreshwa mugutondekanya ibimenyetso bya signal, ariko niki kibatera akamaro cyane? Muri make, RF muyunguruzi irashobora gushungura urusaku rushobora kugira ingaruka kumiterere cyangwa imikorere ya sisitemu iyo ari yo yose y'itumanaho cyangwa kugabanya kwivanga kw'ibimenyetso byo hanze. Kubura akayunguruzo ka RF birashobora kwangiza ihererekanyabubasha ryibimenyetso, kandi amaherezo bishobora kwangiza inzira yitumanaho.

Kubwibyo, filteri ya RF igira uruhare runini muri sisitemu yitumanaho ridafite umugozi (ni ukuvuga satelite, radar, sisitemu igendanwa, nibindi). Iyo bigeze ku mikorere yimodoka zitagira abapilote (UAS), akamaro ka filteri ya RF iragaragara. Kubura uburyo bwiza bwo kuyungurura bizagira ingaruka kuri UAS muburyo bwinshi, nka:

Urwego rwitumanaho rushobora kugabanuka kubangamira ibintu biterwa nibidukikije. Byongeye kandi, kuba hari umubare munini wibimenyetso bya RF mu kirere bishobora kwangiza bikomeye sisitemu yitumanaho rya UAV. Ibimenyetso bibi biva mubindi bibuga birimo ariko ntibigarukira kuri:; Igikorwa cyibanze cya Wi Fi hamwe nubundi buryo bwitumanaho bukorera muri UAS.

Guhagarika izindi sisitemu zitumanaho bizahagarika umuyoboro witumanaho UAS, bityo bigabanye cyangwa bigabanye urwego rwitumanaho rwa sisitemu.

Kwivanga bizagira ingaruka kandi kuri GPS yakira ibimenyetso bya UAS; Ibi byongera amahirwe yamakosa mugukurikirana GPS. Mugihe kibi cyane, ibi birashobora kuvamo igihombo cyuzuye cyo kwakira ibimenyetso bya GPS.

Hamwe na filteri ya RF ikwiye, kwivanga hanze no guhuza ibimenyetso byakozwe na sisitemu yitumanaho yegeranye birashobora kuvaho byoroshye. Ibi bikomeza ubuziranenge bwibimenyetso byifuzwa mugihe cyo kuyungurura byoroshye ibimenyetso byose bidakenewe.

Mubyongeyeho, filteri ya RF nayo igira uruhare runini mubidukikije bya terefone igendanwa. Ku bijyanye na terefone zigendanwa, bakeneye umubare runaka wa bande ya frequency kugirango ikore neza. Bitewe no kubura akayunguruzo ka RF, imirongo itandukanye yumurongo ntizishobora kubana icyarimwe, bivuze ko imirongo imwe nimwe izangwa, aribyo, Global Navigation Satellite Sisitemu (GNSS), umutekano rusange, Wi Fi, nibindi. Hano, filteri ya RF igira uruhare runini mukwemerera amatsinda yose kubana icyarimwe.

Muri rusange, muyunguruzi biroroshye muburemere kandi bifasha kunoza imikorere yumurongo wikimenyetso. Niba akayunguruzo ka RF kadatanga imikorere yifuzwa, noneho urashobora gushakisha ubundi buryo butandukanye, bumwe murubwo bwo kongeramo amplifier mubishushanyo byawe. Kuva kuri gride amplifier kugeza kubindi byose byongera ingufu za RF, urashobora guhindura ibimenyetso bya signal yo hasi kuri signal nyinshi; Kugirango rero tunoze imikorere rusange yubushakashatsi bwa RF.

Si Chuan Keenlion Microwave ihitamo rinini muburyo bwagutse kandi bwagutse, bikubiyemo imirongo kuva kuri 0.5 kugeza kuri 50 GHz. Byaremewe gukora kuva kuri 10 kugeza 30 watt yinjiza muri sisitemu yohereza 50-ohm. Microstrip cyangwa stripline ibishushanyo birakoreshwa, kandi bigashyirwa mubikorwa byiza.

Turashobora kandi gutunganya RF Filter dukurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
