Amakuru

Akugabanya ingufuigabanya ikimenyetso cyinjiye mo ibimenyetso bibiri (cyangwa byinshi) bisohoka. Mu gihe cyiza, igikoresho cyo kugabanya ingufu gishobora gufatwa nk'aho nta gihombo kirimo, ariko mu by'ukuri hariho uburyo bwo gukwirakwiza ingufu. Kubera ko ari umuyoboro uhuza, igikoresho cyo kugabanya ingufu gishobora kandi gukoreshwa nk'igikoresho cyo kugabanya ingufu, aho imiyoboro ibiri (cyangwa myinshi) ikoreshwa mu guhuza ibimenyetso byinjiye mu musaruro umwe. Mu buryo bw'imitekerereze, igikoresho cyo kugabanya ingufu n'igikoresho cyo kugabanya ingufu bishobora kuba igice kimwe, ariko mu by'ukuri hashobora kubaho ibisabwa bitandukanye ku bikoresho byo kugabanya ingufu n'ibikoresho byo kugabanya ingufu, nko gucunga ingufu, guhuza ibice, guhuza imiyoboro no kwitandukanya.

Ibitandukanya ingufu n'ibihuza imbaraga bikunze kwitwa ibitandukanya ingufu. Nubwo ibi ari ukuri mu buryo bwa tekiniki, injeniyeri akenshi zifata ijambo "ibitandukanya" kugira ngo bivuze inyubako ihendutse igabanya ingufu ku buryo bunini cyane, ariko ikaba ifite igihombo kinini kandi ikaba ifite ubushobozi buke bwo gucunga ingufu.

Ijambo "divider" rikunze gukoreshwa iyo ikimenyetso cyinjiye kizagabanywamo kimwe ku bisohoka byose. Urugero, niba hari imiyoboro ibiri yo gusohora, buri imwe yabona munsi gato y'igice cy'ikimenyetso cyinjiye, byaba byiza -3 dB ugereranije n'ikimenyetso cyinjiye. Niba hari imiyoboro ine yo gusohora, buri muyoboro wabona kimwe cya kane cy'ikimenyetso, cyangwa -6 dB ugereranije n'ikimenyetso cyinjiye.

Kwishyira mu kato

Mu guhitamo ubwoko bw'umusemburo cyangwa umusemburo ugomba gukoresha, ni ngombwa gutekereza ku kwitandukanya. Kwitandukanya cyane bivuze ko ibimenyetso by'impanuka (muri umusemburo) bitabangamirana, kandi ingufu zose zitaroherejwe ku musemburo zirasenyuka aho koherezwa kuri pouteur. Ubwoko butandukanye bw'umusemburo bubikora mu buryo butandukanye. Urugero, muri Wilkinson divider, resistor ifite agaciro ka 2Z0 kandi ihambiriye ku musemburo. Muri quadrature coupler, pouteur ya kane ifite iherezo. Iherezo ntirikuraho ingufu keretse habayeho ikintu kibi, nko kuba amplifier imwe yananiwe cyangwa amplifier zifite ibyiciro bitandukanye.

Ubwoko bw'Ibitandukanya

Hariho ubwoko bwinshi n'ubwoko butandukanye bw'ibitandukanya imbaraga cyangwa ibihuza. Bimwe muri byo bikunze kugaragara birimo:

Wilkinson power divider

Itsinda rya Wilkinson rigabanya ikimenyetso cy’inyongera mo ibimenyetso bibiri bingana, cyangwa rigahuza ibimenyetso bibiri bingana mu cyerekezo kimwe mu cyerekezo gitandukanye. Itsinda rya Wilkinson rikoresha transformers za quarter-wave kugira ngo rihuze n’aho itandukaniye. Resistor ishyirwa ku bisohoka, aho ntacyo byangiza ku kimenyetso cy’inyongera kuri Port 1. Ibi birushaho kunoza itandukaniro kandi bigatuma ports zose zihuzwa n’impedance. Ubu bwoko bw’itsinda rigabanya intera bukunze gukoreshwa muri sisitemu za radio frequency nyinshi kuko bushobora gutanga urwego rwo hejuru rwo kwitandukanya hagati y’aho isohoka. Mu gukwirakwiza ibice byinshi bya quarter-wave, Wilkinson ishobora gukora byoroshye bandwidths za 9:1 za sisitemu za elegitoroniki.

Nk'uko izina ribisobanura, icyuma gitandukanya ingufu za RF/microwave kizagabanya ikimenyetso cy’injira mo ibimenyetso bibiri bingana kandi bisa (ni ukuvuga mu cyiciro). Gishobora kandi gukoreshwa nk'igikoresho gihuza ingufu, aho icyambu gisanzwe ari cyo gisohoka naho icyambu cy’amashanyarazi bibiri bingana kikaba ari cyo gikoreshwa. Ibisobanuro by'ingenzi iyo gikoreshejwe nk'icyambu gitandukanya ingufu birimo igihombo cyo kwinjira, ubwinshi bw'amabanga n'icyiciro hagati y'amaboko, n'igihombo cyo kugaruka. Ku bijyanye no guhuza ingufu z'ibimenyetso bidafite aho bihuriye, igipimo cy'ingenzi ni ukwitandukanya, ari cyo gihombo cyo kwinjira kuva kuri kimwe cyambu cy'amashanyarazi kingana ujya ku kindi.

Ibigabanya ububashaIbiranga

• Ibikoresho bigabanya ingufu bishobora gukoreshwa nk'ibihuza cyangwa ibigabanya

• Wilkinson na High isolation power dividers bitanga ahantu henshi ho kwitandukanya, bikinga itumanaho ry'ibimenyetso hagati y'aho ibicuruzwa bisohoka

• Gushyiramo ibintu bike no kugaruka kw'ibintu bidafite akamaro

• Wilkinson n'ibikoresho bigabanya imbaraga bitanga ubwinshi bwiza cyane (<0.5dB) hamwe n'uburinganire bw'ibyiciro (<3°)

Microwave ya Si Chuan Keenlion ni ubwoko bwinshi bw'imashini zigabanya ingufu mu buryo bubiri mu miterere ya narrowband na broadband, zikora ku murongo kuva kuri DC kugeza kuri 50 GHz. Zagenewe 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.

Dushobora kandi guhindura igikoresho cyo kugabanya ingufu ukurikije ibyo ukeneye. Ushobora kwinjira ku ipaji yo guhindura kugira ngo utange ibisobanuro ukeneye.
