Ceramic dielectric resonator oscillator aging [PDF]

open access: yesProceedings of IEEE 48th Annual Symposium on Frequency Control, 2002
Two ceramic dielectric resonator oscillators (CDROs), one operating at center frequency of 1.5 GHz and the other one operating at 8.3 GHz, are being investigated for frequency aging characteristics. The oscillators were ovenized in a Sigma temperature chamber with aging temperature set at +65/spl deg/C.
