ABSTRACT:
Method for stabilizing the frequency of a frequency synthesizer by means of a reference oscillator unit coupled to a voltage controlled oscillator (VCO) and a frequency synthesizer, wherein the synthesizer is provided with a phase locked loop (PLL) to stabilize the operation of the voltage controlled oscillator, wherein the reference oscillator unit is a MEMS (MicroElectromechanicalSystems) reference oscillator unit, the temperature of the MEMS reference oscillator unit is measured, and the output frequency is corrected according to the measured temperature by using a frequency/temperature function.
