Sichuan Keenlion Ikoranabuhanga rya Microwave --—kugabanya imbaraga
Ikoranabuhanga rya Sichuan Keenlion Microwave Yashinzwe mu 2004, Sichuan Keenlion Mircrowave techenology CO., Ltd. ni iya mbere mu gukora ibice bya Passive Mircrowave i Sichuan Chengdu, mu Bushinwa.
Dutanga imikorere-yimikorere ya mirrowave hamwe na serivisi zijyanye na porogaramu ya microwave murugo no mumahanga. Ibicuruzwa birahenze cyane, harimo gutandukanya imbaraga zitandukanye, guhuza icyerekezo, gushungura, guhuza, duplexers, ibikoresho byabigenewe byabigenewe, kwigunga no kuzenguruka. Ibicuruzwa byacu byateguwe byumwihariko kubidukikije bikabije nubushyuhe. Ibisobanuro birashobora gutegurwa ukurikije ibyo umukiriya asabwa kandi birakurikizwa kumurongo wose usanzwe kandi uzwi cyane hamwe numuyoboro utandukanye kuva DC kugeza 50GHz.
kugabanya imbaraga

Igabana imbaragani igikoresho kigabanya ingufu zerekana ibimenyetso byinjira mubice bibiri cyangwa byinshi kandi bisohora ingufu zingana cyangwa zingana. Na none, irashobora guhuza imbaraga nyinshi zerekana ibimenyetso mubisohoka. Muri iki gihe, birashobora kandi kwitwa combiner.

Urwego runaka rwo kwigunga rugomba kwemezwa hagati yicyambu gisohoka amashanyarazi. Imbaraga zikwirakwiza nazo zitwa kurenza-kugabura, kugabanijwe mubikorwa kandi byoroshye. Irashobora gukwirakwiza ikimenyetso kimwe mubisubizo byinshi. Mubisanzwe, buri sub umuyoboro ufite dB nyinshi. Kwiyongera kw'abagabuzi batandukanye nabyo biratandukanye kubera ibimenyetso byerekana ibimenyetso bitandukanye. Kugirango hishyurwe attenuation, pasive power igabanya nyuma yo kongeramo amplifier.

Intangiriro

Igikorwa cyo gukwirakwiza amashanyarazi ni ukugabanya kimwe icyogajuru niba ibimenyetso byinjira biva kumuyoboro umwe muburyo butandukanye bwo gusohora, mubisanzwe harimo ibice bibiri byamashanyarazi, ibice bine byamashanyarazi, ibice bitandatu byamashanyarazi nibindi. Imikoreshereze n'imikorere y'ibikoresho bitatu byavuzwe haruguru biratandukanye rwose, ariko akenshi biroroshye kwitiranya amazina mugukoresha burimunsi, bigatuma abantu bitiranya imikoreshereze. Imashini nyinshi yakira satelite muri sisitemu yo kwakira televiziyo igabana antenne imwe, antene nyinshi zisangira imashini imwe, hamwe niyakira zirenga ebyiri hamwe na antene zirenga ebyiri. Usibye insinga, ihuriro hagati yaryo rigerwaho ahanini no guhuza

gahunda yo guhinduranya. Ikwirakwiza ryamashanyarazi rikoreshwa muguhuza ibyogajuru byinshi. Niba antenne ikeneye guhuzwa na satelite nyinshi yakira, hagomba gukoreshwa gukwirakwiza amashanyarazi. Hitamo gukwirakwiza amashanyarazi ukurikije umubare wabakiriye bahujwe. Niba imashini ebyiri zahujwe, amashanyarazi abiri akoreshwa. Huza imashini enye kandi ukoreshe amashanyarazi ane.

Ibipimo bya tekiniki

Ibipimo bya tekiniki yo gukwirakwiza ingufu zirimo intera yumurongo, gutwara imbaraga, gutakaza igihombo kuva kumuzunguruko mukuru kugeza kumashami, igihombo cyo kwinjiza hagati yinjiza nibisohoka, kwigunga hagati yicyambu cyamashami, igipimo cya voltage ihagaze kuri buri cyambu, nibindi.

1. Urutonde rwinshuro. Nibikorwa byakazi bya RF / microwave itandukanye. Igishushanyo mbonera cyogukwirakwiza amashanyarazi gifitanye isano rya hafi nakazi kenshi. Inshuro zakazi zabakwirakwiza zigomba gusobanurwa mbere yuko igishushanyo gikurikira gishobora gukorwa

2. Kurwanya imbaraga. Mububasha bukomeye bwo gukwirakwiza / synthesizer, imbaraga ntarengwa ibice byumuzunguruko bishobora kwihanganira ni indangagaciro yibanze, igena uburyo bwo kohereza umurongo ushobora gukoreshwa kugirango ugere ku gikorwa cyo gushushanya. Mubisanzwe, gahunda yingufu zitwarwa numurongo wogukwirakwiza kuva muto kugeza munini ni umurongo wa microstrip, umurongo, umurongo wa coaxial, umurongo windege hamwe numurongo wa coaxial. Nuwuhe murongo ugomba guhitamo ukurikije igishushanyo mbonera.

3. Kugabana igihombo. Igihombo cyo kugabura kuva kumuzunguruko kugeza kumuzunguruko wamashami bifitanye isano cyane nigipimo cyo gukwirakwiza ingufu zogukwirakwiza amashanyarazi. Kurugero, igihombo cyo gukwirakwiza ibice bibiri bingana imbaraga ni 3dB naho icya kane kigabanya ingufu ni 6dB.

4. Gutakaza kwinjiza. Igihombo cyo kwinjiza hagati yinjiza nibisohoka biterwa numuyoboro udatunganye cyangwa uyobora umurongo wogukwirakwiza (nkumurongo wa microstrip), urebye igihombo cyatewe numubare uhagaze kumurongo winjiye.

5. Kwigunga. Gutandukanya ibyambu by'ishami ni ikindi kimenyetso cyingenzi cyo gukwirakwiza ingufu. Niba imbaraga zinjiza muri buri cyambu cyishami zishobora gusohoka gusa ku cyambu gikuru kandi ntigomba gusohoka muyandi mashami, bisaba kwigunga bihagije hagati yamashami.

6.Igipimo cyo guhagarara. Gutoya VSWR ya buri cyambu, nibyiza.

Uwitekakugabanya imbaragairashobora kugabanywamo ibyiciro bibiri ukurikije imiterere:

（1 characteristics Ibintu nyamukuru biranga imbaraga zitandukanya imbaraga ni: imikorere ihamye, imiterere yoroshye kandi ahanini nta rusaku; Ingaruka nyamukuru yacyo nuko igihombo cyo kwinjira ari kinini cyane.

（2 power Imbaraga zigabanya imbaraga zigizwe na amplifier. Ibintu nyamukuru biranga ni: inyungu no kwigunga cyane. Ingaruka nyamukuru zayo ni urusaku, imiterere igoye kandi ugereranije no gukora nabi. Icyambu gisohoka cyingufu zigabanya ingufu ebyiri, ingingo eshatu zingufu, ingingo enye zamashanyarazi, ingingo esheshatu zamashanyarazi, umunani wumuriro nimbaraga cumi na zibiri.

Izina ryuzuye ryigabana imbaraga ni igabana imbaraga. Nigikoresho kigabanya ingufu zerekana ibimenyetso byinjira mubice bibiri cyangwa byinshi kandi bisohora ingufu zingana cyangwa zingana. Na none, irashobora guhuza imbaraga nyinshi zerekana ibimenyetso mubisohoka. Muri iki gihe, birashobora kandi kwitwa combiner. Urwego runaka rwo kwigunga rugomba kwemezwa hagati yicyambu gisohoka amashanyarazi. Ukurikije ibyasohotse, ubusanzwe amashanyarazi agabanyijemo kabiri mo kabiri (icyinjijwe kimwe n’ibisohoka bibiri), kimwe muri bitatu (icyinjijwe kimwe n’ibisohoka bitatu), n'ibindi. Ibipimo nyamukuru bya tekiniki yo kugabanya amashanyarazi harimo gutakaza ingufu (harimo gutakaza insimburangingo, gutakaza igihombo no gutakaza ibitekerezo), igipimo cy’umuvuduko w’umuvuduko wa buri cyambu, kwigunga hagati y’ibyambu bikwirakwiza amashanyarazi, kuringaniza ingufu, ubwinshi bw’umuriro n’ubugari bw’umurongo.

Turashobora kandi gutunganya ibice bya rf bikurikije ibyo usabwa. Urashobora kwinjiza urupapuro rwihariye kugirango utange ibisobanuro ukeneye.
