Abstract
Systems and methods for frequency drift compensation for a dielectric resonator oscillator and systems and methods to reduce temperature drift in a dielectric resonator oscillator are provided. Some systems can include an oscillator circuit and a dielectric resonator electrically coupled to the oscillator circuit. The oscillator circuit can have a first temperature coefficient, and the dielectric resonator can have a second temperature coefficient to compensate for frequency drift caused by the first temperature coefficient of the oscillator circuit.
