DRO e khuts'oane bakeng sa dielectric oscillator, e tsejoang hape e le crystal oscillator, e leng mohloli o tsitsitseng le o tšepahalang oa maqhubu.

Karolo e ka sehloohong ea DRO ke ho fetolela lets'oao le tobileng la hona joale hore e be lets'oao le phahameng la AC.Litšobotsi tse phahameng tsa DRO tsa Q li etsa hore e sebetse e le karolo ea "microwave crystal oscillator", e leng bonolo ho finyella lerata le tlaase la karolo ea mohloli oa maqhubu a microwave;DRO e na le coefficient ea mocheso oa maqhubu a resonance e ka ba le litšobotsi tse ntle kapa tse mpe, e ntlafatsa haholo ts'ebetso ea ho hoholeha ha mocheso oa maqhubu a DRO;Le hoja DRO e sa khone ho finyella multifrequency ea Broadband, e na le melemo ha e sebetsa ka makhetlo a mangata.

Likarolo tse ling li kenyelletsa:

1.Botsitso bo phahameng ba maqhubu: li-oscillators tsa dielectric resonator li na le botsitso bo phahameng ba maqhubu le mefuta e fokolang ea liphetoho tsa makhetlo a mangata, e leng se etsang hore e be tse loketseng ka ho khetheha bakeng sa likopo tse phahameng tsa ho laola maqhubu.
2.Boleng ba boleng bo phahameng: Ntho ea boleng ba dielectric resonator oscillators e phahame haholo, e ka hlahisang matšoao a nang le li-harmonics tse tlaase, ho kena-kenana le ho fokotseha ha matla, ho thusang ho ntlafatsa ts'ebetso ea tsamaiso.
3.Botsitso bo phahameng ba mocheso: Ho tsitsa ha maqhubu a dielectric resonator oscillators ho molemo ka mocheso o fapaneng 'me ha ho amehe habonolo ke liphetoho tsa mocheso.
4.Lerata la mekhahlelo e tlaase: Ha ho bapisoa le li-oscillator tse ling, li-oscillator tsa dielectric resonator li na le lerata le tlaase la mekhahlelo 'me ka kakaretso li sebelisa mekhoa ea ho fokotsa lerata ho tsoela pele ho fokotsa lerata la mekhahlelo.
5.Ho bonolo ho kopanya: li-oscillators tsa dielectric resonator li ka sebelisoa lipotolohong tse kopantsoeng, tse nang le molumo o monyenyane le matla a tlaase a matla, a loketseng likopo tse hlokang miniaturization le matla a tlaase a matla.Ka lebaka la litšobotsi tsena, li-oscillator tsa dielectric resonator li sebelisoa haholo mafapheng a kang puisano ea satellite, tsamaiso ea radar, puisano ea sesole, sefofane le lipatlisiso tsa saense.

Qualwavefana ka mefuta e fapaneng ea DRO, khafetsa ho fihla ho 30GHz, lerata la mekhahlelo e tlase, lipontšo tsohle li ntle, li sebelisoa haholo libakeng tse ngata.
