• Kugabanya ikimenyetso mo ibimenyetso bibiri bifite amplitude ingana n'itandukaniro rihoraho rya 90° cyangwa 180°.
• Ku bijyanye no guhuza ibice bine cyangwa gukora ihuza ry’ibice bitandatu/ibitandukanye.
Intangiriro
Ibikoresho bihuza n'ibihujwe ni ibikoresho aho imirongo ibiri yohereza inyura hafi cyane kugira ngo ingufu zikwirakwizwe ku murongo umwe kugira ngo zifatanye n'undi murongo. Ibihujwe bya 3dB 90° cyangwa 180° bigabanyije ikimenyetso cyinjiye mu bisohoka bibiri bingana bya amplitude. Ibihujwe bihuza mu buryo bw'icyerekezo ubusanzwe bigabanyije ikimenyetso cyinjiye mu bisohoka bibiri bitangana bya amplitude. Iri jambo "ibihujwe bihuza mu cyerekezo", "90° hybrid", na "180° hybrid" rishingiye ku buryo busanzwe. Ariko, ibihujwe bya 90° na 180° bishobora gufatwa nk'ibihujwe bihuza mu cyerekezo bya 3 dB. Nubwo hari ibi bisa, ibipimo bikoreshwa mu gusobanura urujya n'uruza rw'ibimenyetso mu bihujwe bihuza mu cyerekezo kandi ikoreshwa, mu mikoreshereze nyayo, biratandukanye bihagije ku buryo bikwiye kwitabwaho bitandukanye.
Ibisobanuro by'imikorere y'ibinyabutabire bya 180° Hybrids
Ihuriro rya 180° ni igikoresho gifite imiyoboro ine gitanga ibimenyetso bibiri bingana mu cyiciro iyo gitanzwe bivuye kuri port yayo y'ingano (S) n'ibimenyetso bibiri bingana bya 180° hanze y'igice iyo gitanzwe bivuye kuri port yayo y'itandukaniro (D). Ku rundi ruhande, ibimenyetso byinjira muri port C na D bizongera kuri port y'ingano (B) kandi itandukaniro ry'ibimenyetso bibiri rizagaragara kuri port y'itandukaniro (A). Ishusho ya 1 ni igishushanyo mbonera kizakoreshwa muri iyi ngingo kugira ngo gigaragaze ihuriro rya 180°. Port B ishobora gufatwa nk'ihuriro ry'ingano naho port A ikaba ari isoko y'itandukaniro. Port A na B na port C na D ni imiyoboro ibiri itandukanye.
90° Hybrids cyangwa hybrid couplers ni 3 dB directional couplers aho phase y'ikimenyetso cyo gusohora hamwe n'ikimenyetso cyo gusohora biri hagati ya 90°. Kubera ko -3 dB ihagarariye igice cy'ingufu, 3 dB coupler igabanya ingufu mu buryo bungana (muri tolerance runaka) hagati y'ibisohoka n'ibisohoka bihujwe. Itandukaniro ry'ibisohoka rya 90° hagati y'ibisohoka rituma hybrids ziba ingirakamaro mu gushushanya ibyuma bipima ibintu mu buryo bw'ikoranabuhanga, microwave mixers, modulators n'ibindi bice byinshi bya microwave na sisitemu. Ishusho ya 5 igaragaza igishushanyo mbonera cy'uruziga n'imbonerahamwe y'ukuri bizakoreshwa mu gusobanura imikorere ya RF frequency 90° hybrid. Nkuko bigaragara kuri iyi mbonerahamwe, ikimenyetso gikoreshwa ku kintu icyo ari cyo cyose cyinjiye kizavamo ibimenyetso bibiri bingana bya amplitude ari quadrature, cyangwa 90°, bitari mu cyiciro kimwe. Ports A na B na Ports C na D ziratandukanye. Nkuko byavuzwe mbere mu gice cya 180° hybrid, RF na microwave frequency devices bikoresha uburyo butandukanye bwo kubaka. Nubwo ibisubizo by'ibitekerezo ari bimwe, aho port iherereye n'uburyo ikoreshwa biratandukanye. Hasi, ku Ishusho hari verisiyo "cross-over" na "non-crossover" zitangwa kuri microwave frequencies (500 MHz no hejuru) hamwe n'imbonerahamwe y'ukuri iboneka. Imvange mirongo icyenda na dogere nazo zitwa quadrature hybrids kuko icyiciro cy'ibisohoka bibiri gitandukanye na quadrant (90°). Menya kandi ko ntacyo bihindura ku imvange ari yo inyuramo igihe cyose isano iri hagati y'imvange ikiriho. Ibi biterwa nuko imvange ya 90° ihuza amashanyarazi n'imikorere ya mekanike kuri X na Y Axes zombi.
Si Chuan Keenlion Microwave ni ubwoko bwinshi bw'ikiraro cya 3DB hybrid mu buryo bwa narrowband na broadband, gifata umurongo kuva kuri 0.5 kugeza kuri 50 GHz. Zagenewe 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.
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 3DB Hybrid Bridge dukurikije ibyo ukeneye. Ushobora kwinjira ku ipaji yo guhindura kugira ngo utange ibisobanuro ukeneye.
