Near-Field Radiation of Millimeter Wave Power Amplifier

With the development of advanced packaging, electromagnetic interference from monolithic microwave integrated circuits (MMIC) has emerged as a significant noise source impacting electronic system stability. However, there is little work reported yet. To calculate the electromagnetic field distribution above this work proposes a linear superposition method to represent the non-linear response of a transistor using harmonic power sources. The results by using a GaN millimeter wave power amplifier MMIC show that the proposed method can capture the near-field electromagnetic field characteristics while maintaining good accuracy in predicting nonlinear performance, The results of the work are useful for compact electronic system optimization.
