Amakuru

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.
coupler
Ikwirakwizwa ryingufu zo kugabanya ibimenyetso bya RF mumiyoboro ibiri ugereranije no kuyisohora muri sisitemu yo kugaburira antene

Porogaramu nyamukuru
(1) Gushyira mu bikorwa uruziga
Coupler irashobora gukora logique zitandukanye. Kuberako ibikorwa byo kurwanya kwivanga no kwigunga bya kupler biruta ibya transistor, inzira ya logique yashizweho nayo irizewe.
Imirima yo gusaba hamwe nibihe bya coupler
(2) Gusaba nkuburyo bukomeye bwa leta
Mumuzunguruko, akenshi birasabwa kugira amashanyarazi meza hagati yumuzunguruko no kugenzura, bikaba bigoye kumurongo rusange wa elegitoronike, ariko biroroshye kubimenya hamwe na kupler.
(3) Gusaba muri trigger circuit
Iyo kupler ikoreshwa mumashanyarazi asohoka, ikibazo cyo kwigunga hagati yumusaruro nu mutwaro kirashobora gukemurwa neza kuko LED irashobora guhuzwa mukurikirane mukuzunguruka gusohora imiyoboro ibiri ikurikiranye.
(4) Gusaba muri pulse amplification circuit
Abashakanye bakoreshwa muburyo bwa digitale kugirango bongere ibimenyetso bya pulse.
(5) Gusaba kumurongo uzunguruka
Umurongo uhuza umurongo ukoreshwa mumuzunguruko, ufite umurongo muremure hamwe nubutaka bwiza bwamashanyarazi.
(6) Gusaba mu bihe bidasanzwe
Coupler irashobora kandi gukoreshwa mugucunga ingufu nyinshi, gusimbuza transformateur, gusimbuza relay hamwe na A / D.

Ibipimo bya tekiniki
1. Impamyabumenyi yo guhuza: itandukaniro ritaziguye hagati yimbaraga zisohoka zivuye ku cyambu hamwe nimbaraga zo kwinjiza ibimenyetso iyo imbaraga zerekana ibimenyetso zinyuze muri kuperi.
2. Impamyabumenyi yo kwigunga: bivuga kwigunga hagati yicyambu gisohoka nicyambu cyo guhuza; Mubisanzwe, iyi index ikoreshwa gusa mugupima microstrip coupler. Kandi biratandukana ukurikije urwego rwo guhuza: urugero, 5-10db ni 18 ~ 23dB, 15dB ni 20 ~ 25dB, naho 20dB (harimo hejuru) ni 25 ~ 30dB; urwego rwo kwigunga rwa cavity coupler nibyiza cyane, kubwibyo rero nta gisabwa kuriyi ngingo.
3. Ubuyobozi: bivuga agaciro ko kwigunga hagati yicyambu gisohoka nicyambu cyo gukuramo ukuyemo agaciro ka dogere. Kubera ko icyerekezo cya microstrip kigabanuka gahoro gahoro hamwe no kwiyongera kurwego rwo guhuza, mubyukuri ntabubasha buri hejuru ya 30dB, kubwibyo rero nta cyerekezo nkicyo gisabwa kuri microstrip coupler. Ubuyobozi bwa cavity coupler muri rusange ni 17 ~ 19dB kuri 1700 ~ 2200MHz, 824 ～ 960MHz: 18 ～ 22dB.
4. Uburyo bwo kubara: directivity = kwigunga - guhuza.
5. Igihombo cyo gushiramo: bivuga agaciro kabonetse mugukuramo agaciro k'igabanywa ryaturutse ku mbaraga zagabanijwe zagabanutse ziva mu mbaraga z'ikimenyetso zinyuze muri kuperi kugeza ku bisohoka. Mubisanzwe, igihombo cyo kwinjiza microstrip coupler kiratandukana ukurikije urwego rwo guhuza. Mubisanzwe, ni 0.35 ~ 0.5dB kuri munsi ya 10dB na 0.2 ~ 0.5dB kurenza 10dB.
6. Iyinjiza / ibisohoka bihagaze ku kigereranyo: bivuga guhuza ibyinjira / ibisohoka ibyambu, kandi ibisabwa kuri buri cyambu muri rusange ni 1.2 ~ 1.4;
7. Kwihanganira imbaraga: bivuga kwihanganira imbaraga ntarengwa zo gukora zishobora kunyura muri iyi coupler igihe kirekire (nta byangiritse). Mubisanzwe, impuzandengo ya microstrip coupler ni 30 ~ 70W, naho ya cavity ni 100 ~ 200W.
8. Urutonde rwinshuro: muri rusange, nominal nominal ni 800 ~ 2200MHz. Mubyukuri, umurongo usabwa ni 824-960MHz wongeyeho 1710 ~ 2200MHz. Hagati yumurongo wo hagati ntushobora kuboneka.
9. Muri bande Flatness: bivuga itandukaniro riri hagati yikigereranyo ntarengwa kandi ntarengwa cyo guhuza murwego rwose rushoboka. Microstrip muri rusange ni 0.5 ~ 0.2db. Cavity: kubera ko impamyabumenyi ihanitse ari umurongo, nta bisabwa nkibyo.

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