DRO ndiyofupikitsa dielectric oscillator, yomwe imadziwikanso kuti crystal oscillator, yomwe ndi gwero lokhazikika komanso lodalirika la ma frequency.

Ntchito yayikulu ya DRO ndikusinthira siginecha yachindunji kukhala ma frequency apamwamba a AC.Makhalidwe apamwamba a DRO amapangitsa kuti ikhale ngati gawo la "microwave crystal oscillator", yomwe imakhala yosavuta kukwaniritsa phokoso lotsika la gwero la ma frequency a microwave;DRO ali ndi resonance pafupipafupi kutentha koyenera kungakhale zabwino kapena zoipa makhalidwe abwino, kwambiri kusintha DRO pafupipafupi kutentha kutengeka ntchito;Ngakhale DRO sangathe kukwaniritsa Broadband multifrequency, ili ndi zabwino mukamagwira ntchito pafupipafupi.

Zina ndi izi:

1.Kukhazikika kwapang'onopang'ono: oscillators a dielectric resonator amakhala ndi kukhazikika kwafupipafupi komanso kusinthasintha kwapang'onopang'ono, kuwapangitsa kukhala oyenera kwambiri kuwongolera pafupipafupi.
2.Chikhalidwe chapamwamba: Chinthu chamtengo wapatali cha dielectric resonator oscillators ndi chapamwamba kwambiri, chomwe chingathe kupanga zizindikiro ndi ma harmonics otsika, kusokoneza pang'ono, ndi kuchepa kwa mphamvu, zomwe zimathandiza kupititsa patsogolo machitidwe.
3.Kukhazikika kwa kutentha kwapamwamba: Kukhazikika kwafupipafupi kwa dielectric resonator oscillators ndi yabwino pa kutentha kosiyana ndipo sikukhudzidwa mosavuta ndi kusintha kwa kutentha.
Phokoso la 4.Low gawo: Poyerekeza ndi oscillator ena, ma dielectric resonator oscillators ali ndi phokoso lochepa la gawo ndipo nthawi zambiri amagwiritsa ntchito njira zochepetsera phokoso kuti apitirize kuchepetsa phokoso la gawo.
5.Zosavuta kuphatikiza: ma oscillators a dielectric resonator angagwiritsidwe ntchito m'mabwalo ophatikizika, okhala ndi voliyumu yaying'ono komanso kugwiritsa ntchito mphamvu zochepa, oyenera kugwiritsa ntchito zomwe zimafunikira miniaturization komanso kutsika kwamphamvu.Chifukwa cha mawonekedwewa, ma oscillator a dielectric resonator amagwiritsidwa ntchito kwambiri m'magawo monga kuyankhulana kwa satellite, machitidwe a radar, kulumikizana kwankhondo, zakuthambo, ndi kafukufuku wasayansi.

Qualwaveperekani mitundu yosiyanasiyana ya DRO, pafupipafupi mpaka 30GHz, phokoso lotsika, zizindikiro zonse ndizabwino, zimagwiritsidwa ntchito m'magawo ambiri.
