Abstract :
This paper describes the design and performance of a novel, planar 24 GHz low phase noise GaAs HBT dielectric resonator oscillator (DRO) for millimeter wave short range radar sensors for automotive and industrial applications. The detailed design, circuit development and experimental results for the DRO are presented and discussed. The measurement of the oscillator showed a center frequency of 23.82 GHz with a fundamental output power of 3.33 dBm and a phase noise performance of -125.67 dBc/Hz at 100 KHz offset, the lowest yet reported.
