XHUMANA MANJE

I-DRO imfushane ku-dielectric oscillator, eyaziwa nangokuthi i-crystal oscillator, okuwumthombo ozinzile nonokwethenjelwa.

Indima eyinhloko ye-DRO ukuguqula isignali yamanje eqondile ibe isignali ye-AC yemvamisa ephezulu.Izici ze-DRO eziphezulu ze-Q ziyenza isebenze njengendima ye-"microwave crystal oscillator", okulula ukufeza umsindo wesigaba esiphansi somthombo wefrikhwensi ye-microwave;I-DRO ine-resonance frequency lokushisa i-coefficient ingaba yizici ezinhle kakhulu noma ezingezinhle, ithuthukise kakhulu ukusebenza kokushisa kwe-DRO frequency drift;Nakuba i-DRO ingakwazi ukufeza i-broadband multifrequency, inezinzuzo lapho isebenza kumachashazi amachashazi.

Ezinye izici zihlanganisa:

I-1.Ukuzinza okuphezulu kwe-frequency: ama-oscillators e-dielectric resonator ane-high-frequency stability kanye nohlu oluncane lwezinguquko zemvamisa, okubenza bafaneleke ngokukhethekile izinhlelo zokusebenza zokulawula imvamisa ephezulu.
I-2.Isici sekhwalithi ephezulu: Ikhwalithi yekhwalithi ye-dielectric resonator oscillators iphakeme kakhulu, engakwazi ukukhiqiza amasignali ngama-harmonics aphansi, ukuphazamiseka okuphansi, nokulahlekelwa kwamandla aphansi, okusiza ukuthuthukisa ukusebenza kwesistimu.
I-3.Ukuqina kokushisa okuphezulu: Ukuzinza kwemvamisa ye-dielectric resonator oscillators kuhle emazingeni okushisa ahlukene futhi akuthintwa kalula ukushintsha kwezinga lokushisa.
I-4.Umsindo wesigaba esiphansi: Uma kuqhathaniswa namanye ama-oscillator, ama-oscillators e-dielectric resonator anomsindo wesigaba esiphansi futhi ngokuvamile asebenzisa amasu okunciphisa umsindo ukuze aqhubeke nokunciphisa umsindo wesigaba.
I-5.Kulula ukuhlanganisa: ama-oscillators e-dielectric resonator angasetshenziswa kumasekethe ahlanganisiwe, anevolumu encane kanye nokusetshenziswa kwamandla aphansi, afanele izinhlelo zokusebenza ezidinga i-miniaturization kanye nokusetshenziswa kwamandla okuphansi.Ngenxa yalezi zici, ama-oscillator e-dielectric resonator asetshenziswa kabanzi emikhakheni efana nokuxhumana ngesathelayithi, izinhlelo ze-radar, ukuxhumana kwezempi, i-aerospace, kanye nocwaningo lwesayensi.

Qualwavehlinzeka ngezinhlobonhlobo ze-DRO, imvamisa kufika ku-30GHz, umsindo wesigaba esiphansi, zonke izinkomba zinhle, zisetshenziswa kabanzi emikhakheni eminingi.
