Ukubuka Konke Komkhiqizo

Izihlungi ze-cavity ze-Sichuan Keenlion Microwave Technology zaklanywa ngokusebenzisa izakhiwo ezi-resonant ezine-Q ephezulu kakhulu futhi zilungele izinhlelo zokusebenza ezincanyana, ezikhetha kakhulu. Lezi zakhiwo zinganikeza ama-bandwidth amancane njenge-1% ngokukhetha okuphezulu kakhulu kanye nephansi elihle kakhulu lomsindo ophansi. Ukulahlekelwa okuphansi kokufakwa kuhlanganiswe nokuphathwa kwamandla okuhle kuzenza zifaneleke kahle i-transmitter kanye ne-receiver front end. Ukwakheka kwezihlungi ezithuthukisiwe kanye nokwakhiwa kwenza ububanzi be-stopband bube ngaphezu kwemvamisa ephakathi kathathu.

Izihlungi ze-cavity ze-Sichuan Keenlion Microwave Technology zine-assembly ekhethekile yokuvikela ukuvimbela ukuhlukaniswa ngengozi okungadinga ukushintshwa okubizayo noma ukubuyiselwa efektri ukuze kulungiswe kabusha. Umshini oqondile uvumela ukuqashelwa kwezihlungi ze-cavity ezinezici ezincane zefomu lezicelo lapho usayizi ubalulekile khona. Ukuphindaphinda okuhle kakhulu kuwo wonke amayunithi kufezwa ngokulungisa okunembile nokulawula inqubo.

Iphrofayela Yenkampani

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.

Isihlungi se-Lowpass singenye yezingxenye zamagagasi angaphezu kwe-RF, i-microwave kanye ne-millimeter ezinikezwa yi-Sichuan Keenlion Microwave Technology. Isihlungi sethu se-lowpass singathengwa futhi sithunyelwe emhlabeni wonke ngosuku olufanayo nezinye izingxenye zethu ze-RF ezikhona esitokweni.

Isihlungi sokudlula okuphansi:

setha iphuzu lokuvama. Uma imvamisa yesignali iphakeme kunale mvamisa, ayikwazi ukudlula. Kumasignali edijithali, leli phuzu lokuvama liyimvamisa yokunqamula. Uma isizinda sokuvama siphakeme kunale mvamisa yokunqamula, wonke amanani abelwa njengo-0. Ngoba kule nqubo, wonke amasignali okuvama okuphansi adlula, kubizwa ngokuthi ukuhlunga okuphansi

Isibonelo sesihlungi sokudlula okuphansi:

Isithiyo esiqinile siyisihlungi esidlula kancane samaza omsindo. Uma udlala umculo kwelinye igumbi, kulula ukuzwa i-bass yomculo, kodwa iningi le-treble liyahlungwa. Ngokufanayo, umculo ophakeme kakhulu emotweni eyodwa uzwakala njengesigqi se-bass kubantu abakwenye imoto, ngoba ngalesi sikhathi, imoto evaliwe (kanye negebe lomoya) isebenza njengesihlungi esidlula kancane futhi yenza buthaka yonke i-treble.

Izihlungi ze-elekthronikhi ezisebenzisa i-low-pass zisetshenziselwa ukushayela ama-subwoofers nezinye izinhlobo zezikhulumi nokuvimba ukushaya kwe-treble ezingakwazi ukukusabalalisa ngempumelelo.

Ama-radio transmitter asebenzisa izihlungi ezisebenzisa i-low pass ukuvimba ukukhishwa kwe-harmonic okungase kubangele ukuphazamiseka kwezinye izindlela zokuxhumana.

Isihlukanisi se-DSL sisebenzisa izihlungi ze-low-pass kanye ne-high pass ukuze sihlukanise amasignali e-DSL kanye nama-pots abelana nge-twisted pair.

Izihlungi ze-Low pass nazo zidlala indima ebalulekile ekucutshungulweni komsindo womculo we-elekthronikhi owenziwe yi-analog synthesizers njengeRoland.

Isihlungi esifanelekile nesisebenzayo isihlungi esifanelekile esiphansi singasusa ngokuphelele zonke izimpawu zemvamisa ezingaphezu kwemvamisa yokusika, futhi izimpawu ezingaphansi kwemvamisa yokusika zingadlula zingathinteki. Indawo yangempela yokuguqula ayisekho. Isihlungi esifanelekile esiphansi singatholakala ngendlela yezibalo (ngokwethiyori) siphindaphinda isignali ngomsebenzi ongunxande kusizinda semvamisa. Njengendlela enomphumela ofanayo, ingatholakala futhi ngokuguqulwa komsebenzi we-sinc kusizinda sesikhathi.

Kodwa-ke, isihlungi esinjalo asikwazi ukutholakala ngesignali yangempela yangempela. Lokhu kungenxa yokuthi umsebenzi we-sinc uwumsebenzi ofinyelela ku-infinity. Ngakho-ke, isihlungi esinjalo sidinga ukubikezela ikusasa futhi sibe nayo yonke idatha yesikhathi esidlule ukuze senze i-convolution. Lokhu kungenzeka ngesignali yedijithali eqoshiwe ngaphambilini (u-zero wengezwa ngemuva kwesignali ukuze iphutha elihlungiwe elivelayo libe ngaphansi kwephutha le-quantization) noma isignali yomjikelezo ongenamkhawulo.

Izihlungi ezisebenzayo ezinhlelweni zokusebenza zesikhathi sangempela zilinganisa isihlungi esifanele ngokubambezela isignali isikhathi esifushane ukuze zikwazi "ukubona" ​​ingxenye encane yesikhathi esizayo, okuye kwafakazelwa ukushintsha kwesigaba. Uma ukunemba kokulinganisa kuphakeme, kulapho ukubambezeleka kudingeka khona isikhathi eside.

Ithiyori yokusampula ichaza indlela yokwakha kabusha isignali eqhubekayo kusuka ekuhlolweni kwesignali yedijithali usebenzisa isihlungi esiphelele esiphansi kanye nefomula yokufakelwa kwe-Nyquist Shannon. Abaguquli bangempela bedijithali kuya ku-analog basebenzisa izihlungi ezilinganiselwe.

Imibuzo Evame Ukubuzwa

U: Uyini umbono wakho we-R&D yomkhiqizo?

A: Ukusungula izinto ezintsha kushintsha isiko futhi ikhwalithi iholela esikhathini esizayo.
