Implementation of RF frequency synthesizer for smart utility network system

A wideband frequency synthesizer has been designed and fabricated to generate 780MHz(China), 868MHz(Europe), and 915MHz(Korea, North America) of three bands at the same time. It will be applied in the IEEE 802.15.4g SUN system. Measurement results show the frequency synthesizer has wide bandwidth of...

More Information
Summary:A wideband frequency synthesizer has been designed and fabricated to generate 780MHz(China), 868MHz(Europe), and 915MHz(Korea, North America) of three bands at the same time. It will be applied in the IEEE 802.15.4g SUN system. Measurement results show the frequency synthesizer has wide bandwidth of 1527~2020MHz(about 27.8% of center frequency) and low phase noise characteristics of -98.63dBc/Hz at 100KHz offset, -122.05dBc/Hz at 1MHz offset.
