    Phase noise measurement using a interferometric measurement technique

    Jan. 14, 2025
    This paper describes the measurement of additive/residual phase noise of power amplifiers or multipliers for automotive radar sensors at 80 GHz using the interferometric measurement approach in combination with a phase noise and VCO tester.

    Learn how to use the interferometric measurement approach in combination with a phase noise test system to characterize the additive/residual phase noise of amplifiers down to -150 dBc/Hz at 100 kHz to offset the microwave range at 80 GHz.
