    The STuW81300 includes a dual architecture frequency synthesizer (Fractional-N and Integer- N), four low phase noise VCOs with a fast automatic center frequency calibration providing a very wide frequency range, from 1.925 GHz to 16 GHz, with a single device.


    The STuW81300 optimizes size and cost of the final application by the integration of low noise LDO voltage regulators and internally matched broadband RF outputs.


    Additional features include a crystal oscillator core, external VCO mode, output mute function and low power mode to trade current consumption with phase noise performance and/or output level.
