• Kugabanya ikimenyetso mubimenyetso bibiri bya amplitude angana hamwe na 90 ° cyangwa 180 ° itandukanya icyiciro.
• Kuri quadrature ihuza cyangwa ikora incamake / itandukanye.
Intangiriro
Coupler na Hybride ni ibikoresho aho imirongo ibiri yohereza inyura hafi yizindi kugirango ingufu zikwirakwira kumurongo umwe kugeza kubashakanye kumurongo. Hybrid ya 3dB 90 ° cyangwa 180 ° igabanya ibimenyetso byinjira mubice bibiri bingana na amplitude. Icyerekezo gifatika gisanzwe kigabanya ibimenyetso byinjira mubisubizo bibiri bingana na amplitude. Iri jambo “guhuza icyerekezo”, “90 ° hybrid”, na “180 ° hybrid” rishingiye ku masezerano. Nyamara, imvange ya 90 ° na 180 ° zishobora gutekerezwa nka 3 dB ihuza icyerekezo. Nubwo ibyo bisa, ibipimo bikoreshwa mugusobanura ibimenyetso bitembera mubyerekezo bihuza hamwe na porogaramu, mugukoresha nyabyo, biratandukanye bihagije kugirango umuntu atekereze.
180 ° Hybride Ibisobanuro bikora
Hybrid ya 180 ° nigikoresho gisubirana cyicyambu cya kane gitanga amplitude abiri angana mubyiciro byicyiciro iyo bigaburiwe kuva ku cyambu cyayo (S) hamwe na amplitude abiri angana na 180 ° bitarenze icyiciro iyo bigaburiwe ku cyambu cyacyo gitandukanye (D). Ibinyuranye, ibimenyetso byinjira mubyambu C na D bizongera ku cyambu (B) kandi itandukaniro ryibimenyetso byombi bizagaragara ku cyambu gitandukanye (A). Igishushanyo 1 nigishushanyo mbonera kizakoreshwa muriyi ngingo kugirango kigereranye imvange ya 180 °. Icyambu B gishobora gufatwa nkicyambu hamwe nicyambu A nicyo cyambu gitandukanye. Ibyambu A na B hamwe nicyambu C na D ni bibiri byicyambu.
90 ° Hybride cyangwa ibivangavanze ni 3 dB ihuza icyerekezo aho icyiciro cyibimenyetso bisohoka hamwe nibisohoka bisohoka 90 ° bitandukanye. Kubera ko -3 dB igereranya igice cyimbaraga, 3 dB ihuza igabanya imbaraga zingana (muburyo bwo kwihanganira) hagati yibisohoka hamwe nibisohoka byambu. Itandukanyirizo rya 90 ° hagati yibisohoka bituma ibivange bigira akamaro mugushushanya ibintu bya elegitoroniki bihindagurika, kuvanga microwave, modulator hamwe nibindi byinshi bya microwave hamwe na sisitemu. Igicapo 5 cerekana igishushanyo mbonera hamwe nimbonerahamwe yukuri bizakoreshwa mugusobanura imikorere ya RF frequency 90 ° hybrid. Nkuko bigaragara kuri iki gishushanyo, ikimenyetso gikoreshwa mubyinjijwe byose bizavamo ibimenyetso bibiri bingana amplitude ari quadrature, cyangwa 90 °, bitarangiye hamwe. Ibyambu A na B hamwe na C na D byitaruye. Nkuko byavuzwe mbere mu gice cya 180 ° hybrid, ibikoresho bya RF na microwave bikoresha uburyo butandukanye bwo kubaka. Nubwo ibisubizo byuburyo bisa, icyambu hamwe nibisanzwe biratandukanye. Hasi, mubishushanyo ni "cross-over" na "non-cross-cross" verisiyo zitangwa kuri microwave yumurongo (500 MHz no hejuru) hamwe nimbonerahamwe yukuri. Impamyabumenyi ya dogere mirongo icyenda nayo yitwa quadrature hybrid kuko icyiciro cyibisubizo byombi ari quadrant (90 °) itandukanye. Menya kandi ko ntacyo bihindura icyambu nicyo cyambu cyinjira mugihe cyose umubano uri hagati yicyambu. Ni ukubera ko 90 ° Hybride ifite amashanyarazi hamwe nubukanishi hafi ya X na Y Axes.
Si Chuan Keenlion Microwave ihitamo rinini ryikiraro cya 3DB cyivanga mumirongo migari hamwe nu murongo mugari, 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.
Ibice biza bisanzwe hamwe na SMA cyangwa N ihuza abategarugori, cyangwa 2,92mm, 2.40mm, na 1.85mm ihuza ibice byinshi.
Turashobora kandi gutunganya ikiraro cya 3DB Hybrid dukurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
