After an initial review of the vertically integrated resonator structure, an extracted temperature drift profile of the ceramic substrate is utilized to estimate the temperature dependence of the oscillation frequency of the entire circuit. Adding a low sensitivity tuning structure combined with a low complexity thermistor-network, the temperature shift can be significantly reduced from plusmn50 MHz to about plusmn5 MHz in an interval of 50 K, entirely compensating the drift at around room temperature. Finally, the impact of the additional tuning structure on the phase noise performance is analyzed.encavity resonatorsceramic packagingcircuit noisecircuit tuningcompensationmicrowave oscillatorsphase noisethermistorsvoltage-controlled oscillatorstemperature drift compensationK-band hybrid voltage-controlled oscillatorLTCC hybrid voltage-controlled oscillatorvertically integrated resonator structureceramic substrateoscillation frequencylow complexity thermistor-networklow sensitivity tuning structurelow temperature co-fired ceramicsrectangular cavity resonatorfrequency 20 GHzTemperature sensorsVoltage-controlled oscillatorsTemperature dependenceFrequency estimationCircuit optimizationTuningK-bandCeramicsPhase noisePerformance analysisJournal ArticleOther
