Akugabanya imbaragaigabanya ibimenyetso byinjira mubice bibiri (cyangwa byinshi) bisohoka. Mugihe cyiza, igabana imbaraga zirashobora gufatwa nkigihombo-gito, ariko mubikorwa harigihe habaho imbaraga zo gutandukana. Kuberako numuyoboro usubiranamo, umuhuza wamashanyarazi urashobora kandi gukoreshwa nkumuhuza wamashanyarazi, aho ibyambu bibiri (cyangwa byinshi) bikoreshwa muguhuza ibimenyetso byinjira mubisohoka rimwe. Mu buryo bw'igitekerezo, imbaraga zigabanya imbaraga hamwe nimbaraga zishobora kuba ibice bimwe, ariko mubikorwa hashobora kubaho ibisabwa bitandukanye kubihuza no kubitandukanya, nko gukoresha amashanyarazi, guhuza icyiciro, guhuza ibyambu no kwigunga.

Gutandukanya imbaraga hamwe na combiners bakunze kwitwa gutandukana. Mugihe ibi aribyukuri muburyo bwa tekiniki, injeniyeri mubusanzwe abika ijambo "splitter" kugirango asobanure imiterere ihendutse irwanya imbaraga igabanya imbaraga kumurongo mugari cyane, ariko ifite igihombo kinini kandi ikoresha ingufu nke.

Ijambo "kugabana" rikoreshwa cyane mugihe ibimenyetso byinjira bizagabanywa neza mubisubizo byose. Kurugero, niba hari ibyambu bibiri bisohoka, buri kimwe cyabona munsi ya kimwe cya kabiri cyibimenyetso byinjira, nibyiza -3 dB ugereranije nibimenyetso byinjira. Niba hari ibyambu bine bisohoka, buri cyambu cyabona hafi kimwe cya kane cyibimenyetso, cyangwa -6 dB ugereranije nibimenyetso byinjira.

Kwigunga

Mugihe uhisemo ubwoko bwo gutandukanya cyangwa guhuza gukoresha, ni ngombwa gutekereza ku bwigunge. Kwigunga cyane bivuze ko ibimenyetso byabaye (muri kombineri) bitavangira, kandi ingufu zose zoherejwe mubisohoka ziratangwa aho koherezwa ku cyambu gisohoka. Ubwoko butandukanye bwabatandukanya bakemura ibi muburyo butandukanye. Kurugero, mugice cya Wilkinson, résistoriste ifite agaciro ka 2Z0 kandi ihambiriye kumusaruro. Muri quadrature coupler, icyambu cya kane gifite iherezo. Kurangiza ntibisohora imbaraga keretse habaye ikintu kibi kibaye, nka amp imwe yananiwe cyangwa amplifier ifite ibyiciro bitandukanye.

Ubwoko bw'abatandukanya

Hariho ubwoko bwinshi nubwoko butandukanye bwo kugabana imbaraga cyangwa guhuza. Bimwe mubisanzwe bikunze kuboneka harimo:

Wilkinson imbaraga zigabanya

Igabana rya Wilkinson rigabanya ibimenyetso byinjira mubice bibiri bingana ibyasohotse bisohoka, cyangwa bihuza ibimenyetso bibiri bingana icyiciro kimwe muburyo butandukanye. Igabana rya Wilkinson ryishingikiriza kuri kimwe cya kane-gihinduranya guhuza icyambu. Ristoriste ishyirwa hejuru yibisohoka, aho ntacyo byangiza kubimenyetso byinjira kuri Port 1. Ibi bitezimbere cyane kwigunga kandi bituma ibyambu byose bibangikanya. Ubu bwoko bwo gutandukanya bukoreshwa kenshi mumirongo myinshi ya radiyo yumurongo wa radiyo kuko irashobora gutanga urwego rwo hejuru rwo kwigunga hagati yibisohoka. Mugukurikirana ibice byinshi byigihembwe, ibya Wilkinson birashobora gukemura byoroshye umurongo wa 9: 1 wa sisitemu yintambara ya elegitoroniki.

Nkuko izina ribivuga, RF / microwave power divider izagabanya ibimenyetso byinjira mubice bibiri bingana kandi bisa (ni ukuvuga mubice). Irashobora kandi gukoreshwa nkimbaraga zihuza imbaraga, aho icyambu gisanzwe aricyo gisohoka kandi ibyambu bibiri bingana byifashishwa nkibisubizo. Ibisobanuro byingenzi iyo bikoreshejwe nkigabanura imbaraga harimo igihombo cyo gushiramo, amplitude hamwe nuburinganire hagati yintwaro, no gutakaza igihombo. Ku mbaraga zihuza ibimenyetso bidafitanye isano, icyangombwa cyingenzi ni ukwigunga, nicyo gihombo cyo kwinjiza kuva ku cyambu kimwe kingana ku kindi.

Abatandukanya ImbaragaIbiranga

• Gutandukanya ingufu birashobora gukoreshwa nka kombineri cyangwa ibice

• Wilkinson hamwe nogutandukanya imbaraga zitanga imbaraga zitanga kwigunga cyane, guhagarika ibimenyetso byambukiranya ibiganiro hagati yicyambu

• Kwinjiza bike no gutakaza igihombo

• Wilkinson hamwe nimbaraga zigabanya imbaraga zitanga amplitude nziza (<0.5dB) hamwe na (<3 °) impagarike yicyiciro

Si Chuan Keenlion Microwave ihitamo rinini ryamashanyarazi 2-muburyo bwo kugabanya umurongo mugari hamwe nu murongo mugari, bikubiyemo imirongo kuva kuri DC 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.

Ibice biza bisanzwe hamwe na SMA cyangwa N ihuza abategarugori, cyangwa 2,92mm, 2.40mm, na 1.85mm ihuza ibice byinshi.

Turashobora kandi guhitamo imbaraga zigabanya imbaraga ukurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
