Abstract

In this paper an approach of developing high performance millimeterwave frequency synthesizer is proposed which is significantly simpler than the conventional cases The synthesizer is driven by one triple tuned typed synthesizer which adjusts the output frequency of DDS and frequency division ratios of variable frequency divider to suppress the spurious level With the proposed method a microwave phase locked loop PLL PE3236 and a millimeterwave multiplier HMC283 are also used Moreover the PLL is implemented with the form of charge pump followed by a passive threeorder lowpass filter which can further suppress the phase noise Finally a low spurious level and high frequency resolution millimeterwave frequency synthesizer without degradation of frequency switching speed is developed Experimental results show that this method can achieve the performances of low spurious level low phase noise and high frequency resolution
