Additive Phase Noise in RF & Microwave Amplifiers Part 4 – Low Level RF Measurement Tutorial

Mini-Circuits R&D Fellow, Joe Merenda recently presented a tutorial on Amplifier Additive Phase Noise at the 2025 Low-Level Radio Frequency Workshop at the Thomas Jefferson National Accelerator Facility in Newport News, VA. In this fourth episode of our Additive Phase Noise series, he shares this tutorial for the benefit of the broader RF and microwave engineering community. In this session, Joe explains the measurement setup and reviews fundamentals of additive phase noise theory. He then discusses differences between small signal and large signal behavior and the effect of AM-PM distortion on APN performance. The tutorial concludes with practical cases of additive phase noise performance in various cascade design examples.
