The evolution of the dielectric resonator filter (DRF) design is discussed and the incorporation of this design into a low-noise dielectric resonator oscillator (DRO) is described. The results of each intermediate step are included along with the final results. The unique properties of the DRF allow it to have a loaded Q of >6500 at 1.538 GHz with an insertion loss of ~6 dB while maintaining a vibration sensitivity 2.2×10-8 (G-1). The use of high-pressure bonding and the elimination of the metallization at the cavity and substrate interface allows this configuration to work
