High-Efficiency Transmission Line Baluns for Enhanced mm-Wave PA Performance

Abstract

The increasing demand for high-speed, high-frequency communications underscores the importance of advancements in millimeter-wave (mm-Wave) technology, especially for power amplifiers (PAs) that operate efficiently at these frequencies. This paper explores the design and performance of high-efficiency transmission line baluns, crucial for enhancing the functionality of mm-wave PAs. Utilizing 0.25μm Indium Phosphide (InP) technology, a new balun design is proposed to elevate mm-Wave PA performance. The discussion begins with exploring balun operational principles, emphasizing their role in providing a balanced drive to PAs to maximize power-added efficiency (PAE) and minimize signal distortion. The paper discusses the implications of these enhancements for mm-wave communication systems, such as 5G, and future applications. High-efficiency transmission line baluns represent a significant step forward in mm-Wave PA technology, offering a promising direction for further research and development in high-frequency communication systems.
