As the demand for high-speed wireless communication continues to grow, efficient PA design becomes critical for supporting modern communications network infrastructure, especially in the sub-20GHz spectrum (FR1 and FR3 bands). This workshop will delve into comprehensive design and development of power amplifiers (PAs) for sub-20GHz base station applications. The latest processes and technologies will be covered, focusing on semiconductor advances that drive power handling, linearity, and efficiency. Participants will explore theory and modeling principles to predict performance and optimize PA designs for various operational scenarios. The session will also emphasize architecture and design techniques, addressing key challenges such as linearity, efficiency, and bandwidth. Finally, the workshop will cover module design and integration, where participants will learn about packaging considerations and thermal management to ensure optimal performance in real-world deployments. This workshop is ideal for RF engineers, circuit designers, and researchers aiming to enhance their expertise in cutting-edge PA technology for wireless infrastructure. Participants will gain an in-depth understanding of key PA architecture and design techniques through interactive sessions with practical case studies.
