Low phase noise 55MHz-15GHz fractional-N synth

ADI’s ADF5610 fractional-N synthesiser covers 55MHz to 15GHz, and is claimed to have “industry’s lowest phase noise performance on a single chip” by its maker. Fabbed on a SiGe BiCMOS process, at 10GHz VCO phase noise is -114dBc/Hz at 100kHz offset and -165dBc/Hz at 100MHz offset. Normalized phase noise floor is -229dBc/Hz. Typical output power is  ...
