Izindaba

Ubuchwepheshe be-Microwave beSichuan Keenlion Obusungulwe ngo-2004, i-Sichuan Keenlion Mircrowave techenology CO., Ltd. ingumkhiqizi ohamba phambili wezingxenye ze-Passive Mircrowave eSichuan Chengdu, eShayina.
Sinikeza izingxenye ze-mirrowave ezisebenza kahle kakhulu kanye nezinsizakalo ezihlobene nezinhlelo zokusebenza ze-microwave ekhaya nakwamanye amazwe. Imikhiqizo ishibhile, kufaka phakathi i-power divider ehlukahlukene, ama-directional couplers, ama-filters, ama-combiners, ama-duplexers, izingxenye ezingasebenzi ezenziwe ngokwezifiso, ama-isolators nama-circulator. Imikhiqizo yethu yenzelwe ngokukhethekile izindawo ezahlukene kanye namazinga okushisa aphezulu. Imininingwane ingakhiwa ngokuya ngezidingo zamakhasimende futhi isebenza kuwo wonke ama-frequency band ajwayelekile nathandwayo anama-bandwidth ahlukahlukene kusukela ku-DC kuya ku-50GHz.
i-coupler
Ingxenye yokusatshalaliswa kwamandla yokuhlukanisa isignali ye-RF ibe iziteshi ezimbili ngokulingana bese uyikhipha ohlelweni lwe-antenna feeder

Izinhlelo zokusebenza eziyinhloko
(1) Ukusetshenziswa kwesekethe ye-logic
I-coupler ingakha amasekethe ahlukahlukene e-logic. Ngenxa yokuthi ukusebenza kwe-coupler okulwa nokuphazamiseka kanye nokuhlukaniswa kungcono kunokwe-transistor, isekethe ye-logic eyakhiwe yiyo ithembeke kakhulu.
Amasimu okusetshenziswa kanye nezikhathi zokuxhuma
(2) Isicelo njengesishintshi sesimo esiqinile
Kusekhethi yokushintsha, kuvame ukudingeka ukuthi kube nokuhlukaniswa okuhle kukagesi phakathi kwesekethe yokulawula kanye neswishi, okuyinto enzima kuswishi ejwayelekile kagesi, kodwa kulula ukuyiqonda nge-coupler.
(3) Ukusetshenziswa kusekethe ye-trigger
Uma i-coupler isetshenziswa kusekethe yokukhipha e-bistable, inkinga yokuhlukaniswa phakathi kokukhipha nomthwalo ingaxazululwa ngempumelelo ngoba i-LED ingaxhunywa ngokulandelana kusekethe ye-emitter yamashubhu amabili ngokulandelana.
(4) Ukusetshenziswa kwesekethe yokukhulisa i-pulse
Ama-couplers asetshenziswa kumasekethe edijithali ukukhulisa izimpawu zokushaya kwenhliziyo.
(5) Ukusetshenziswa kwesekethe eqondile
I-Linear coupler isetshenziswa ku-linear circuit, enomugqa ophezulu kanye nokusebenza okuhle kakhulu kokuhlukaniswa kukagesi omhlaba.
(6) Isicelo ngezikhathi ezikhethekile
I-coupler ingasetshenziswa futhi ekulawuleni i-voltage ephezulu, ukufaka esikhundleni se-transformer, ukufaka esikhundleni se-contact relay kanye ne-A / D circuit.

Izinkomba zobuchwepheshe
1. Izinga lokuxhuma: umehluko oqondile phakathi kwamandla okukhipha avela echwebeni lokuxhuma kanye namandla esignali yokufaka lapho amandla esignali edlula e-coupler.
2. Izinga lokuhlukaniswa: libhekisela ekuhlukanisweni phakathi kwembobo yokukhipha kanye nembobo yokuhlanganisa; Ngokuvamile, le nkomba isetshenziswa kuphela ukukala i-microstrip coupler. Futhi iyahlukahluka ngokuya ngezinga lokuhlanganisa: isibonelo, i-5-10db ingu-18 ~ 23dB, i-15dB ingu-20 ~ 25dB, kanti i-20dB (kufaka phakathi ngenhla) ingu-25 ~ 30dB; izinga lokuhlukaniswa kwe-cavity coupler lihle kakhulu, ngakho-ke akukho mfuneko yale nkomba.
3. Ukuqondisa: kubhekisela enanini lokuhlukaniswa phakathi kwembobo yokukhipha kanye nembobo yokuxhuma ngaphandle kwenani lezinga lokuxhuma. Njengoba ukuqondisa kwe-microstrip kwehla kancane kancane ngokwanda kwezinga lokuxhuma, ngokuyisisekelo akukho ukuqondisa okungaphezu kuka-30dB, ngakho-ke akukho mfuneko enjalo yenkomba ye-microstrip coupler. Ukuqondisa kwe-cavity coupler ngokuvamile kungu-17 ~ 19dB ku-1700 ~ 2200MHz, 824 ～ 960MHz: 18 ～ 22dB.
4. Indlela yokubala: isiqondiso = ukuhlukaniswa - ukuxhumanisa.
5. Ukulahlekelwa kokufakwa: kubhekisela enanini elitholwe ngokususa inani lokulahlekelwa kokusabalalisa emandleni esignali ancishisiwe emandleni esignali ngokusebenzisa i-coupler kuya kokukhiphayo. Ngokuvamile, ukulahlekelwa kokufakwa kwe-coupler ye-microstrip kuyahlukahluka ngokuya ngezinga lokuhlanganisa. Ngokuvamile, kungu-0.35 ~ 0.5dB ngaphansi kuka-10dB kanye no-0.2 ~ 0.5dB ngaphezu kuka-10dB.
6. Isilinganiso segagasi lokuma lokufaka/lokukhipha: sibhekisela ekufanisweni kwama-port okufaka/okukhiphayo, futhi izidingo ze-port ngayinye ngokuvamile ziyi-1.2 ~ 1.4;
7. Ukubekezelelana kwamandla: kubhekisela ekubekezeleni kwamandla okusebenza okuphezulu okungadlula kulesi sixhumi isikhathi eside (ngaphandle komonakalo). Ngokuvamile, amandla ajwayelekile esixhumi se-microstrip angama-30 ~ 70W, kanti amandla omgodi angama-100 ~ 200W.
8. Ububanzi bemvamisa: ngokuvamile, imvamisa ejwayelekile ingu-800 ~ 2200MHz. Eqinisweni, ibhendi yemvamisa edingekayo ingu-824-960MHz kanye no-1710 ~ 2200MHz. Ibhendi yemvamisa ephakathi ayitholakali.
9. Kubhendi Ukuthamba: kubhekisela emehluko phakathi kwezinga eliphezulu nelincane lokuhlanganisa kubhendi yonke yemvamisa etholakalayo. I-Microstrip ngokuvamile ingu-0.5 ~ 0.2db. Umgodi: njengoba izinga lokuhlanganisa liyijika, asikho isidingo esinjalo.

Singakwazi futhi ukwenza ngezifiso izingxenye ze-rf passive ngokwezidingo zakho. Ungangena ekhasini lokwenza ngezifiso ukuze unikeze imininingwane oyidingayo.
