Dielectric Resonator Oscillators (DROs)

A Dielectric Resonator Oscillator or DRO is a type of electronic oscillator that is designed to generate high frequency signals. The DRO consists of a hollow metallic enclosed tube that exhibits resonance behavior when excited by an electromagnetic field. Resonance is a characteristic frequency of an RF system when it reaches the maximum degree of oscillation. The metallic tube is typically constructed using materials with low loss and a high dielectric constant, to ensure that most of the electromagnetic fields will be contained within the dielectric medium. The resonating frequency of a DRO also depends upon the physical dimensions of the dielectric material used. Circular, rectangular, hemispherical, and cylindrical are some of the predominant shapes that are preferred for designing these oscillators. DROs are ideal for tuned amplifiers, frequency meters, antennas, bandpass filters, bandstop filters, frequency-selective limiters, and phased equalizer applications.
