DRO gajere ne don oscillator dielectric, wanda kuma aka sani da oscillator crystal, wanda shine tsayayye kuma ingantaccen tushen mita.

Babban aikin DRO shine canza siginar halin yanzu kai tsaye zuwa siginar AC mai girma.Halayen Q na DRO masu girma sun sa ya zama matsayin "microwave crystal oscillator", wanda ya fi sauƙi don cimma ƙaramar ƙararrakin lokaci na tushen mitar microwave;DRO yana da madaidaicin mitar zafin jiki na iya zama tabbatacce ko mara kyau kyawawan halaye, haɓaka haɓaka mitar zazzabi na DRO sosai;Kodayake DRO ba zai iya cimma yawan mitar watsa labarai ba, yana da fa'idodi yayin aiki a mitar digo.

Sauran siffofi sun haɗa da:

1.High mitar kwanciyar hankali: dielectric resonator oscillatorss suna da kwanciyar hankali mai girma da ƙananan sauye-sauye na mita, yana sa su musamman dacewa da aikace-aikacen sarrafa mitar mai mahimmanci.
2.High quality factor: Matsayin ingancin dielectric resonator oscillators yana da girma sosai, wanda zai iya haifar da sigina tare da ƙananan jituwa, ƙananan tsangwama, da ƙananan asarar makamashi, wanda ke taimakawa wajen inganta tsarin aiki.
3.High zafin jiki kwanciyar hankali: Matsayin kwanciyar hankali na dielectric resonator oscillators yana da kyau a yanayin zafi daban-daban kuma ba a sauƙaƙe ta hanyar canjin yanayi.
4.Low lokaci amo: Idan aka kwatanta da sauran oscillators, dielectric resonator oscillators da ƙananan lokaci amo da kullum amfani da amo rage dabaru don kara rage lokaci amo.
5.Easy don haɗawa: dielectric resonator oscillatorss za a iya amfani da su a cikin haɗin gwiwar da'irori, tare da ƙarami ƙarami da ƙananan amfani da wutar lantarki, dace da aikace-aikacen da ke buƙatar miniaturization da ƙananan amfani.Saboda waɗannan halayen, dielectric resonator oscillators ana amfani da su sosai a fannoni kamar sadarwar tauraron dan adam, tsarin radar, sadarwar soja, sararin samaniya, da binciken kimiyya.

Qualwavesamar da nau'ikan DRO iri-iri, mita har zuwa 30GHz, ƙaramar ƙarar lokaci, duk alamun suna da kyau, ana amfani da su sosai a fagage da yawa.
