Izindaba

I-Sichuan Keenlion Microwave Technology Yasungulwa ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye zePassive Mircrowave eSichuan Chengdu, eChina.
Sihlinzeka ngezingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezicelo ze-microwave ekhaya naphesheya. Imikhiqizo ibiza kakhulu, kufaka phakathi isihlukanisi samandla ahlukahlukene, ama-couplers aqondisayo, izihlungi, izihlanganisi, ama-duplexer, izakhi ezenziwe ngokwezifiso zokungenzi lutho, ama-isolator nama-circulator. Imikhiqizo yethu iklanyelwe ngokukhethekile izindawo ezihlukahlukene eziyingozi kanye namazinga okushisa. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi iyasebenza kuwo wonke amabhendi amafrikhwensi ajwayelekile nadumile anomkhawulokudonsa ohlukahlukene ukusuka ku-DC kuye ku-50GHz.
i-coupler
Ingxenye yokusabalalisa amandla yokuhlukanisa isignali ye-RF ibe amashaneli amabili ngokulingana bese iwakhiphela ohlelweni lwe-antenna feeder

Izinhlelo zokusebenza eziyinhloko
(1) Isicelo kumjikelezo we-logic
I-coupler ingakha amasekhethi e-logic ahlukahlukene. Ngenxa yokuthi ukuphikisana nokuphazanyiswa nokusebenza kokuhlukaniswa kwe-coupler kungcono kunaleyo ye-transistor, isifunda esinengqondo esakhiwe yiyo sithembeke kakhulu.
Izinkambu zohlelo lokusebenza kanye nezikhathi ze-coupler
(2) Isicelo njengokushintsha kwesimo esiqinile
Emjikelezweni wokushintsha, kuvame ukudingeka ukuthi kube nokuhlukaniswa okuhle kukagesi phakathi kwesifunda sokulawula kanye nokushintsha, okunzima ekushintsheni okujwayelekile kwe-elekthronikhi, kodwa kulula ukukubona nge-coupler.
(3) Isicelo kumjikelezo we-trigger
Uma i-coupler isetshenziswa kumjikelezo okhiphayo we-bistable, inkinga yokuhlukaniswa phakathi kokuphumayo nomthwalo ingaxazululwa ngempumelelo ngoba i-LED ingaxhunywa ngochungechunge kusekethe ye-emitter yamashubhu amabili ngokulandelanayo.
(4) Isicelo kumjikelezo wokukhulisa i-pulse
Imibhangqwana isetshenziswa kumasekhethi edijithali ukukhulisa amasignali okushaya kwenhliziyo.
(5) Isicelo kumjikelezo womugqa
I-coupler yomugqa isetshenziswa kumjikelezo womugqa, onokulingana okuphezulu nokusebenza okuhle kakhulu kokuhlukaniswa kukagesi ophansi.
(6) Ukufaka isicelo ngezikhathi ezikhethekile
I-coupler ingasetshenziswa futhi ekulawuleni i-voltage ephezulu, esikhundleni se-transformer, esikhundleni se-relay yokuxhumana kanye nesekethe ye-A / D.

Izinkomba zobuchwepheshe
1. Idigri yokuhlanganisa: umehluko oqondile phakathi kwamandla okukhiphayo asuka kumbobo yokuhlanganisa namandla esignali yokufaka lapho amandla esignali edlula ku-coupler.
2. Idigri yokuhlukanisa: ibhekisela ekuhlukaniseni phakathi kwembobo yokuphumayo kanye nembobo yokuhlanganisa; Ngokuvamile, le nkomba isetshenziswa kuphela ukukala i-microstrip coupler. Futhi iyahlukahluka ngokuya ngezinga lokuhlanganisa: isibonelo, i-5-10db ingu-18 ~ 23dB, 15dB ingu-20 ~ 25dB, kanye no-20dB (okuhlanganisa ngenhla) ngu-25 ~ 30dB; izinga lokuhlukaniswa kwe-cavity coupler lihle kakhulu, ngakho-ke asikho isidingo sale nkomba.
3. Ukuqondisa ngqo: kubhekisela enanini lokuhlukanisa phakathi kwembobo yokukhipha kanye nembobo yokuhlanganisa khipha inani ledigri yokuhlanganisa. Njengoba ukuqondisa kwe-microstrip kuncipha kancane kancane ngokwanda kwezinga lokuhlanganisa, ngokuyisisekelo akukho ukuqondisa okungaphezulu kuka-30dB, ngakho-ke asikho isidingo esinjalo senkomba se-coupler ye-microstrip. Ukuqondisa kwe-cavity coupler ngokuvamile kungu-17 ~ 19dB ku-1700 ~ 2200MHz, 824 ～ 960MHz: 18 ~ 22dB.
4. Indlela yokubala: ukuqondisa = ukuzihlukanisa - ukuhlanganisa.
5. Ukulahlekelwa kokufaka: kubhekisela enanini elitholwe ngokukhipha inani lokulahlekelwa kokusabalalisa kusukela kumandla esignali ancishisiwe kusukela kumandla wesignali ngokusebenzisa i-coupler kuya kokuphumayo. Ngokuvamile, ukulahlekelwa kokufaka kwe-microstrip coupler kuyehluka kuye ngezinga lokuhlanganisa. Ngokuvamile, ingu-0.35 ~ 0.5dB ngaphansi kuka-10dB kanye no-0.2 ~ 0.5dB ngaphezu kuka-10dB.
6. Isilinganiso segagasi lokuma okokufaka / okukhiphayo: sibhekisela ekufaniswaneni kwezimbobo zokufaka / zokukhiphayo, futhi izimfuneko zembobo ngayinye ngokuvamile zingu-1.2 ~ 1.4;
7. Ukubekezelelana kwamandla: kubhekisela ekubekezeleni kwamandla okusebenza okuphezulu okungadlula kule coupler isikhathi eside (ngaphandle kokulimala). Ngokuvamile, isilinganiso samandla e-microstrip coupler singama-30 ~ 70W, futhi leso sikhala singu-100 ~ 200W.
8. Ibanga lefrequency: ngokuvamile, imvamisa okuzisholo ukuthi 800 ~ 2200MHz. Eqinisweni, ibhendi yefrikhwensi edingekayo ingu-824-960MHz kanye no-1710 ~ 2200MHz. Ibhendi yefrikhwensi emaphakathi ayitholakali.
9. I-Flatness yebhendi: ibhekisela kumehluko phakathi kwedigri ephezulu kanye nencane yokuhlanganisa kuyo yonke ibhendi yefrikhwensi etholakalayo. I-Microstrip ngokuvamile ingu-0.5 ~ 0.2db. I-Cavity: njengoba i-coupling degree iyijika, asikho isidingo esinjalo.

Singakwazi futhi ukwenza ngokwezifiso izingxenye ze-rf passive ngokuya ngezidingo zakho. Ungafaka ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
