Tuned DRO & CRO

Tuned DRO (Dielectric Resonator Oscillator) and CRO (Crystal Resonator Oscillator) are types of microwave oscillators used in communication systems, radar systems, and other applications that require a stable and precise frequency source.

Tuned DROs use a dielectric resonator, which is a ceramic block with high dielectric constant, as the frequency reference. The dielectric resonator is excited by a high-Q circuit, such as a varactor diode, and the oscillator frequency is tuned by varying the voltage applied to the varactor diode. Tuned DROs have a high frequency stability and can generate frequencies in the range of several gigahertz.

CROs, on the other hand, use a quartz crystal resonator as the frequency reference. The crystal resonator is cut in a specific orientation and shape that allows it to vibrate at a specific frequency. The oscillator circuit is designed to amplify the crystal's natural vibrations, resulting in a stable and precise oscillator frequency. CROs have a lower frequency stability than DROs, but they can generate frequencies up to several hundred megahertz.
