Sales Briefcase
  • 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.

    Key Features

    • Output frequency range: 1.925 GHz to 16 GHz
      • RF out 1 (VCO, VCO÷2): 1.925-8.0 GHz
      • RF out 2 (VCO x 2): 7.7-16.0 GHz
    • Very Low Noise
      • Normalized phase noise floor: -227 dBc/Hz
      • VCO phase noise (6.0 GHz): -131 dBc/Hz @ 1 MHz offset
      • Noise floor (6.0 GHz): -158 dBc/Hz
      • Phase noise (12 GHz): -125 dBc/Hz @ 1 MHz offset
      • Noise floor (12 GHz): -154 dBc/Hz
    • Integrated VCOs with fast automatic center frequency calibration
    • External VCO option with 5 V charge pump
    • Fundamental VCO rejection at doubler output higher than 20 dB
    • Internally broadband matched RF outputs delivering +6 dBm @6 GHz and +4 dBm @12 GHz single-ended
    • Integrated low noise LDOs
    • Maximum phase detector frequency: 100 MHz
    • Exact frequency mode
    • Differential reference clock input (LVDS and LVECPL compliant) supporting up to 800 MHz
