Abstract: | In this paper, an approach of developing high performance millimeter-wave 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 millimeter-wave multiplier HMC283 are also used. Moreover, the PLL
is implemented with the form of charge pump followed by a passive three-order low-pass filter which can further suppress the
phase noise. Finally, a low spurious level and high frequency resolution millimeter-wave 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. |
