Ni ikiAkayunguruzo ka RF?

Akayunguruzo k'amajwi ya radiyo ni igice cy'ingenzi cy'ikoranabuhanga ritagira umugozi. Kakoreshwa hamwe n'akayunguruzo ka radiyo kugira ngo kayunguruze izindi nsinga zidakenewe kandi kagahabwa gusa umugozi ukwiye. Akayunguruzo ka RF kagenewe gukora byoroshye mu ntera y'amajwi kuva kuri frequence iri hagati kugeza kuri frequence iri hejuru cyane (ni ukuvuga megahertz na gigahertz). Kubera imiterere yako ikora, gakoreshwa cyane muri radiyo, itumanaho ritagira umugozi, televiziyo n'ibindi bikoresho.

Muri rusange, filter nyinshi za RF zigizwe na resonators zifatanye, kandi ubwiza bwazo bushobora kugena urwego rwo kuyungurura muri RF. Dukurikije ikoreshwa n'ingano y'ibikoresho bidafite insinga, hari ubwoko bwinshi bw'filter, ari bwo cavity filter, plane filter, electroacoustic filter, dielectric filter, coaxial filter (itari ku nsinga ya coaxial), n'ibindi.

Ubwoko bw'ibanze bwa filter ya radio frequency

Akayunguruzo ka RF ni urusobe rwihariye rwemerera ibimenyetso nyabyo kunyuramo mu gihe hakurwaho ibimenyetso bidakenewe. Ku bijyanye n'imiterere y'akayunguruzo, hari ubwoko bune bw'ibanze bwa kayunguruzo ka RF, ari bwo kayunguruzo ka henshi, kayunguruzo ka low pass, kayunguruzo ka band pass na kayunguruzo ka band stop

Akayunguruzo k'inzira ntoya:

Nk’uko izina ribisobanura, akayunguruzo k’amajwi make ni akayunguruzo kemerera gusa amajwi make kunyura no kugabanya amajwi y’andi marangamutima icyarimwe. Iyo ikimenyetso kinyuze mu kayunguruzo k’amajwi, kugabanuka kwacyo bigenwa n’ibintu byinshi, nko mu kayunguruzo k’amajwi, imiterere n’ubwiza bw’ibice byacyo. Byongeye kandi, akayunguruzo k’amajwi kagena umuvuduko w’impinduka z’akayunguruzo kava mu kayunguruzo k’amajwi kugira ngo kagere ku guhagarara kwako kwa nyuma.

Akayunguruzo k'amajwi gake kari mu buryo butandukanye. Ikoreshwa ry'ingenzi rya akayunguruzo ni ukugabanya uburyo bwo guhuza imikorere ya amplifier ya RF. Iki gikorwa ni ingenzi kuko gifasha gukumira ingaruka zitari ngombwa ku miyoboro itandukanye yo kohereza ubutumwa. Mbere na mbere, akayunguruzo k'amajwi gake kari gukoreshwa mu bikorwa by'amajwi no gukuramo urusaku ruturutse hanze. Nyuma y'uko ikimenyetso cy'amajwi menshi kiyunguruwe, ingano y'amajwi yabonetse iba ifite ubuziranenge busobanutse.

Akayunguruzo k'inzira nini:

Bitandukanye na filter y'inzira ntoya, filter y'inzira nini yemerera gusa ibimenyetso bya frequency yo hejuru. Mu by'ukuri, filter y'inzira nini n'filter y'inzira ntoya byuzuzanya cyane, kuko filter zombi zishobora gukoreshwa hamwe kugira ngo hakorwe filter y'inzira ya band-pass. Imiterere ya filter y'inzira nini ni direct kandi igabanya frequency iri munsi y'aho umurongo ugarukira.

Muri rusange, ibyuma biyungurura amajwi menshi bikoreshwa muri sisitemu z'amajwi, aho frequencies zose zo hasi ziyungururwa. Byongeye kandi, binakoreshwa mu gukuraho indangururamajwi nto na bass mu bihe byinshi; Izi mashini ziba zubatswe mu ndangururamajwi. Ariko, niba hari umushinga wa DIY urimo, icyuma giyungurura amajwi menshi gishobora guhuzwa byoroshye na sisitemu.

Akayunguruzo k'Inyandiko z'Itsinda:

Akayunguruzo k'amajwi (band-pass filter) ni urujya n'uruza rwemerera ibimenyetso bivuye ku miyoboro ibiri itandukanye kunyuramo no kugabanya ibimenyetso bitari mu rwego rwemewe. Akayunguruzo kenshi k'amajwi (band-pass filters) gashingira ku isoko ry'ingufu zo hanze kandi gakoresha ibice bikora, ni ukuvuga imiyoboro ihuriweho na transistors. Ubwo bwoko bw'akayunguruzo bwitwa akayunguruzo k'amajwi (active band-pass filter). Ku rundi ruhande, amwe mu makayunguruzo y'amajwi (band-pass filters) ntakoresha ingufu zo hanze kandi yishingikiriza cyane ku bice bidakora (passive components), ni ukuvuga inductors na capacitors. Izi kayunguruzo zitwa akayunguruzo k'amajwi (passive band-pass filters).

Akayunguruzo ka Bandpass gakunze gukoreshwa mu byuma byakira n’ibyohereza bidafite umugozi. Akamaro kayo k’ingenzi muri transmitter ni ukugabanya umuvuduko w’ikimenyetso cy’umuvuduko kugeza ku rugero ruto, kugira ngo amakuru akenewe ashobore koherezwa ku muvuduko n’imiterere bisabwa. Iyo icyuma cyakira kigize uruhare, akayunguruzo ka Bandpass kemerera gusa gusesengura cyangwa kumva umubare w’imivuduko isabwa, mu gihe kagabanya andi majwi aturutse ku mivuduko idakenewe.

Muri make, iyo icyuma gikoresha band-pass cyakozwe, gishobora kongera ubwiza bw'ikimenyetso no kugabanya irushanwa cyangwa ubwivanganzo hagati y'ibimenyetso.

Kwanga itsinda:

Rimwe na rimwe yitwa filter yo guhagarika umurongo, filter yo guhagarika umurongo ni filter yemerera imirongo myinshi kunyuramo idahindutse. Ariko, igabanya imirongo iri munsi y'urwego runaka. Imikorere yayo inyuranye rwose n'iya filter yo guhagarika umurongo. Mu by'ukuri, inshingano yayo ni ukurenga umurongo kuva kuri zeru ukagera ku gice cya mbere cyo guhagarika umurongo. Hagati aho, irenga imirongo yose iri hejuru y'igice cya kabiri cyo guhagarika umurongo. Ariko, yanga cyangwa igahagarika indi mirongo yose iri hagati y'izi ngingo ebyiri.

Mu ijambo rimwe, akayunguruzo ni ikintu cyemerera ibimenyetso kunyuramo hifashishijwe agace k'inzira. Mu yandi magambo, agace k'inzira kari muri aka gafunguzo niho imirongo imwe n'imwe yanzwe na akayunguruzo ako ari ko kose. Yaba ari ugutanga ubutumwa bwinshi, ugutanga ubutumwa bugufi cyangwa ugutanga ubutumwa bugufi, akayunguruzo keza ni akayunguruzo kadafite igihombo muri aka gace k'inzira. Ariko, mu by'ukuri, nta kayunguruzo keza gahari kuko agafunguzo k'inzira kazatakaza umurongo kandi ntibishoboka kugera ku guhagarara kutagira iherezo iyo agafunguzo k'inzira kagezeho.

Kuki Filters za Radio Frequency ari ingenzi cyane?

Utwuma twa RF dukoreshwa mu gushyira mu byiciro imirongo y'amajwi, ariko ni iki gituma ari ingenzi cyane? Muri make, utwuma twa RF dushobora gushungura amajwi ashobora kugira ingaruka ku bwiza cyangwa imikorere ya sisitemu iyo ari yo yose y'itumanaho cyangwa kugabanya ukwivanga kw'ibimenyetso byo hanze. Kutagira utwuma twa RF dukwiye bishobora kwangiza uburyo bwo kohereza umurongo w'amajwi, kandi amaherezo bikangiza inzira y'itumanaho.

Bityo rero, ibyuma biyungurura amashanyarazi bigira uruhare runini muri sisitemu z'itumanaho zidafite insinga (urugero: icyogajuru, radar, sisitemu zigendanwa zidafite insinga, nibindi). Ku bijyanye n'imikorere y'imodoka zitagira abapilote (UAS), akamaro ka ibyuma biyungurura amashanyarazi bivuze ko ibyuma biyungurura amashanyarazi bigira ingaruka kuri UAS mu buryo bwinshi, nko:

Ingano y'itumanaho ishobora kugabanuka bitewe n'ingaruka ziterwa n'ibidukikije byo hanze. Byongeye kandi, kuba hari umubare munini w'ibimenyetso bya RF mu kirere bishobora kwangiza cyane sisitemu y'itumanaho ya UAV. Ibimenyetso bibi biva ku zindi mbuga birimo ariko ntibigarukira gusa kuri:; Ibikorwa bikomeye by'ibimenyetso bya Wi Fi n'izindi sisitemu z'itumanaho zikorera muri UAS.

Guhagarika kw'izindi sisitemu z'itumanaho bizahagarika umuyoboro w'itumanaho wa UAS, bityo bikagabanya cyangwa bikagabanya urwego rw'itumanaho rwa izo sisitemu.

Kubangamira bizagira ingaruka ku kwakira ibimenyetso bya GPS bya UAS; Ibi byongera amahirwe yo gukora amakosa mu gukurikirana GPS. Mu gihe kibi kurushaho, ibi bishobora gutuma ibimenyetso bya GPS bitakirwa burundu.

Hamwe n'urufunguzo rwa RF rukwiye, kubangamirana kw'inyuma no kubangamirana kw'amajwi bikomoka kuri sisitemu z'itumanaho zegeranye bishobora gukurwaho byoroshye. Ibi bikomeza ubwiza bw'umuvuduko w'amajwi wifuza mu gihe biyungurura byoroshye umurongo wose w'amajwi udakenewe.

Byongeye kandi, ibyuma bya RF bigira uruhare runini mu bijyanye na telefoni zigendanwa. Ku bijyanye na telefoni zigendanwa, zikenera umubare runaka w'imirongo ya frequency kugira ngo zikore neza. Kubera kutagira ibyuma bya RF bikwiye, imirongo itandukanye ya frequency ntizaba hamwe icyarimwe, bivuze ko imirongo imwe n'imwe ya frequency izangwa, ari yo Global Navigation Satellite System (GNSS), umutekano rusange, Wi Fi, nibindi. Aha, ibyuma bya RF bigira uruhare runini mu gutuma imirongo yose iba hamwe icyarimwe.

Muri rusange, ibyuma bipima ubunini bworoheje kandi bifasha kunoza imikorere y'umuvuduko w'ibimenyetso. Niba icyuma gipima ubunini cya RF kidatanga imikorere wifuza, ushobora gushakisha andi mahitamo atandukanye, imwe muri yo ikaba ari ukongeramo amplifiers ku gishushanyo cyawe. Kuva kuri amplifiers za grid kugeza kuri amplifiers zose za RF, ushobora guhindura umuvuduko muto w'ibimenyetso ukajya kuri frequency nini y'ibimenyetso; Kugira ngo wongere imikorere rusange y'igishushanyo cya RF.

Microwave ya Si Chuan Keenlion ni amahitamo menshi mu miterere ya narrowband na broadband, ifite umurongo wa frequencies kuva kuri 0.5 kugeza kuri 50 GHz. Yagenewe gutwara imbaraga za watts 10 kugeza kuri 30 muri sisitemu yo kohereza ya 50-ohm. Imiterere ya microstrip cyangwa stripline irakoreshwa, kandi ikanozwa kugira ngo ikore neza.

Dushobora kandi guhindura RF Filter dukurikije ibyo ukeneye. Ushobora kwinjira ku ipaji yo guhindura kugira ngo utange ibisobanuro ukeneye.
