Ihuza ryerekezo nubwoko bwingenzi bwibikoresho byo gutunganya ibimenyetso. Igikorwa cyabo cyibanze ni uguhitamo ibimenyetso bya RF kurwego rwateganijwe rwo guhuza, hamwe no kwigunga cyane hagati yicyambu cyerekana ibyambu - bifasha gusesengura, gupima no gutunganya porogaramu nyinshi. Kubera ko ari ibikoresho byoroshye, bikora no muburyo bwinyuma, hamwe nibimenyetso byinjijwe munzira nyamukuru ukurikije icyerekezo cyibikoresho hamwe nurwego rwo guhuza. Hariho itandukaniro rito muburyo bwimikorere ihuza, nkuko tuzabibona hepfo.
Ibisobanuro
Byiza, coupler yaba idafite igihombo, ihuye kandi isubiranamo. Ibintu shingiro byimiyoboro itatu-ine-port ni ukwigunga, guhuza no kuyobora, indangagaciro zikoreshwa mukuranga abashakanye. Ihuza ryiza rifite icyerekezo kitagira umupaka no kwigunga, hamwe nibintu bifatika byatoranijwe kubigenewe.
Igishushanyo gikora mu gishushanyo cya 1 cyerekana imikorere ya coupler yerekanwe, ikurikirwa no gusobanura ibipimo bifitanye isano. Igishushanyo cyo hejuru ni 4-icyuma gihuza, gikubiyemo ibyerekezo byombi (imbere) hamwe na byitaruye (bihindagurika, cyangwa byerekanwe). Igishushanyo cyo hasi ni imiterere ya 3-port, ikuraho icyambu cyitaruye. Ibi birakoreshwa mubisabwa bikenera gusa imbere imwe ihujwe ibisohoka. Ihuza rya 3-port irashobora guhuzwa muburyo bwinyuma, aho icyambu cyahoze gihujwe gihinduka icyambu cyitaruye:
Igishushanyo 1: ShingiroicyerekezoIboneza
Ibiranga imikorere:
Ikintu cyo guhuza: Ibi byerekana agace k'imbaraga zinjiza (kuri P1) zagejejwe ku cyambu cyahujwe, P3
Ubuyobozi: Iki ni igipimo cyubushobozi bwa coupler bwo gutandukanya imiraba ikwirakwiza imbere kandi igana inyuma, nkuko bigaragara ku byambu bihujwe (P3) hamwe na (P4) byitaruye;
Kwigunga: Yerekana imbaraga zagejejwe ku mutwaro udafunze (P4)
Gutakaza Kwinjiza: Iyi konte yimbaraga zinjiza (P1) zagejejwe ku cyambu cyoherejwe (P2), kigabanywa nimbaraga zashyikirijwe ibyambu bifatanye kandi byitaruye.
Indangagaciro zibi biranga muri dB ni:
Guhuza = C = ibiti 10 (P1 / P3)
Ubuyobozi = D = 10 log (P3 / P4)
Kwigunga = I = ibiti 10 (P1 / P4)
Gutakaza Kwinjiza = L = 10 log (P1 / P2)
Ubwoko bw'Abashakanye
Ubu bwoko bwa coupler bufite ibyambu bitatu byoroshye, nkuko bigaragara ku gishushanyo cya 2, aho icyambu cya kane kirangirira imbere kugirango gitange icyerekezo kinini. Igikorwa cyibanze cyerekezo gihuza nicyitegererezo cyitaruye (revers). Porogaramu isanzwe ni gupima imbaraga zigaragara (cyangwa mu buryo butaziguye, VSWR). Nubwo ishobora guhuzwa muburyo butandukanye, ubu bwoko bwa coupler ntabwo busubiranamo. Kubera ko kimwe mu byambu bifatanye cyarangiye imbere, ikimenyetso kimwe gusa kirahari. Mu cyerekezo cyerekezo (nkuko byerekanwe), icyambu cyahujwe cyerekana icyitegererezo cyinyuma, ariko iyo gihujwe nicyerekezo cyinyuma (Iyinjiza rya RF iburyo), icyambu cyahujwe cyaba icyitegererezo cyumuvuduko wimbere, wagabanijwe nibintu bifatika. Hamwe niyi sano, igikoresho gishobora gukoreshwa nkicyitegererezo cyo gupima ibimenyetso, cyangwa gutanga igice cyibisohoka mubisubizo byatanzwe.
Igishushanyo 2: 50-Ohm Icyerekezo Coupler
Ibyiza:
1 、 Imikorere irashobora gutezimbere inzira igana imbere
2 direct Ubuyobozi bukomeye no kwigunga
3 、 Ubuyobozi bwa coupler bugira ingaruka cyane kumikino ya impedance itangwa no kurangiza ku cyambu cyitaruye. Gutwika ibyo kurangiza imbere bitanga imikorere myiza
Ibibi:
1 、 Guhuza biboneka gusa munzira igana imbere
2 、 Nta murongo uhujwe
3 rating Ihuriro ryimbaraga zahujwe ni munsi yicyambu cyinjiza kuko imbaraga zashyizwe kumurongo wahujwe hafi ya zose zarangiye mugihe cyo kurangiza imbere.
Si Chuan Keenlion Microwave ihitamo rinini rya Diregiteri Coupler 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.
