Abstract
The AM/AM and AM/PM characteristics of a power amplifier are typically measured in a static manner using a CW signal. For communications signals, the amplitude envelope is varying so the distortion is actually occurring dynamically. This paper presents a technique to measure dynamic AM/AM and AM/PM. Results are presented for two examples of power amplification: a traveling-wave tube amplifier and a solid-state amplifier.
