Amakuru

Udukoresho duhuza icyerekezo ni ubwoko bw'ingenzi bw'igikoresho gitunganya ibimenyetso. Akazi kabo k'ibanze ni ugupima ibimenyetso bya RF ku rugero rwagenwe rwo guhuza, hamwe no kwitandukanya cyane hagati y'aho ibimenyetso bihurira n'aho byafatiwe icyitegererezo - bishyigikira isesengura, gupima no gutunganya porogaramu nyinshi. Kubera ko ari ibikoresho bidakora, binakora mu cyerekezo gitandukanye, hamwe n'ibimenyetso bishyirwa mu nzira nyamukuru hakurikijwe icyerekezo cy'ibikoresho n'urwego byo guhuza. Hari itandukaniro rike mu miterere y'udukoresho duhuza icyerekezo, nk'uko tuzabibona hano hepfo.

Ibisobanuro

Byaba byiza ko umuhuza (coupler) uba udafite igihombo, uhuye kandi uhuza. Imiterere y'ibanze y'imiyoboro itatu n'ine ni ukwitandukanya, guhuza no kuyobora, agaciro kabyo kagakoreshwa mu kuranga umuhuza. Umuhuza mwiza ufite ubuyobozi n'ubwiyongere butagira iherezo, hamwe n'ikintu gihuza cyatoranijwe mu ikoreshwa ryacyo.

Ishusho y'imikorere iri ku Ishusho ya 1 igaragaza imikorere ya coupler y'icyerekezo, ikurikirwa n'ibisobanuro by'imikorere bifitanye isano. Ishusho yo hejuru ni coupler ifite imiyoboro ine, irimo imiyoboro yombi ihujwe (imbere) n'ihujwe (inyuma, cyangwa igaragara). Ishusho yo hepfo ni imiterere ya 3-ports, ikuraho umuyoboro umwe gusa. Ibi bikoreshwa mu bikorwa bisaba gusa umusaruro umwe uhujwe imbere. Coupler ifite imiyoboro itatu ishobora guhuzwa mu cyerekezo gisubira inyuma, aho umuyoboro wari uhujwe mbere uba umuyoboro wihariye:

Igishushanyo cya 1: Ishingiroumuyoboro w'icyerekezoimikoreshereze

Ibiranga imikorere:

Igipimo cyo guhuza: Ibi bigaragaza igice cy'ingufu z'injira (kuri P1) zigezwa kuri pori ihujwe, P3

Inzira: Iki ni igipimo cy'ubushobozi bwa coupler bwo gutandukanya imiraba ikwirakwira imbere n'inyuma, nk'uko byagaragaye ku byambu bihujwe (P3) n'ibyakuwemo (P4)

Gutandukanya: Bigaragaza imbaraga zitangwa ku mutwaro udafite aho uboheye (P4)

Igihombo cyo gushyiramo: Ibi bikubiyemo ingufu z’injira (P1) zigezwa ku cyambu cyoherejwe (P2), zigabanywa n’imbaraga zigezwa ku cyambu gihujwe n’icyakuwemo.

Agaciro k'ibi biranga muri dB ni:

Guhuza = C = 10 logi (P1/P3)

Inzira y'ubuyobozi = D = 10 logi (P3/P4)

Kwitandukanya = I = 10 logi (P1/P4)

Igihombo cyo gushyiramo = L = logi 10 (P1/P2)

Ubwoko bw'abahuza

Ibikoresho byo guhuza icyerekezo:

Ubu bwoko bw'umuhuza bufite imiyoboro itatu ishoboka, nk'uko bigaragara ku Ishusho ya 2, aho umuhuza wa kane uhagarikwa imbere kugira ngo utange ubuyobozi ntarengwa. Akamaro k'ibanze k'umuhuza w'icyerekezo ni ugupima ikimenyetso cyashyizwe mu mwanya umwe (cyangwa VSWR). Uburyo busanzwe bwo gukoresha ni ugupima imbaraga zigaragara (cyangwa mu buryo butaziguye, VSWR). Nubwo gishobora guhuzwa inyuma, ubu bwoko bw'umuhuza ntabwo buhuza. Kubera ko imwe mu miyoboro ihujwe ihagarikwa imbere, ikimenyetso kimwe gusa gihujwe kiraboneka. Mu cyerekezo cy'imbere (nk'uko bigaragara), umuhuza w'icyerekezo uhujwe upima umuraba usubira inyuma, ariko iyo uhujwe mu cyerekezo cy'inyuma (RF Input iburyo), umuhuza w'icyerekezo waba icyitegererezo cy'umuraba ujya imbere, ugabanijwe n'ikintu gihuza. Hamwe n'iyi miyoboro, igikoresho gishobora gukoreshwa nk'icyitegererezo cyo gupima ikimenyetso, cyangwa gutanga igice cy'ikimenyetso cy'umusaruro ku miyoboro y'ibitekerezo.

Igishushanyo cya 2: Igikoresho cyo guhuza icyerekezo cya 50-Ohm

Ibyiza:

1. Imikorere ishobora kunozwa kugira ngo inzira igere imbere

2. Icyerekezo cyo hejuru no kwitandukanya

3. Inzira y'igikoresho gihuza amashanyarazi iterwa cyane n'impinduka zitangwa n'irangira ry'amashanyarazi ku cyambu cyashyizwe mu mwanya wacyo. Gutanga iyo mpanuka imbere bituma habaho imikorere myiza.

Ibibi:

1. Guhuza ibintu bihari gusa mu nzira yo kugana imbere

2. Nta murongo ufatanye

3. Ingufu za port zifatanye ni nkeya ugereranyije n'ingufu zinjiye kuko ingufu zikoreshwa kuri port zifatanye ziba hafi ya zose mu mpera z'imbere.

Microwave ya Si Chuan Keenlion ni ubwoko bwinshi bwa Directional Coupler mu buryo bwa narrowband na broadband, bufata umurongo kuva kuri 0.5 kugeza kuri 50 GHz. Yagenewe gutwara imbaraga kuva kuri watts 10 kugeza kuri 30 muri sisitemu yo kohereza ya 50-ohm. Imiterere ya microstrip cyangwa stripline irakoreshwa, kandi ikanozwa kugira ngo ikore neza.

Ibikoresho biza bifite ibihuza bya SMA cyangwa N by’abagore, cyangwa ibihuza bya 2.92mm, 2.40mm, na 1.85mm ku bikoresho bifite umurongo munini w’itumanaho.
