Abstract :
We report a 4.596 GHz frequency synthesis based on a 2.1 GHz Solid Mounted Resonator (SMR) voltage controlled oscillator (VCO). The SMR source exhibits a power consumption of about 18 mW, a chip size of 2mm2 and a phase noise of - 89 dBc/Hz at 2 kHz offset frequency. A synthesizer is constructed from this source to generate a low noise 4.596 GHz signal. The synthesizer is preliminary used as a local oscillator in a compact Cs atomic clock based on Coherent Population Trapping (CPT).
