Dr. Shubhankar majumdar of National Institute Of Technology, Meghalaya

RF power amplifiers (PAs) play a critical role in transmitters used in 4G/5G communications, satellite links, radar, and IoT devices, where efficiency, linearity, bandwidth, and thermal stability are key performance metrics. The speaker will discuss device selection, load–pull analysis, impedance matching techniques, stability considerations, harmonic tuning, and efficiency enhancement methods such as Class-F and Doherty architectures. Practical aspects including biasing networks, layout challenges, thermal management, and measurement techniques will also be covered. The session aims to bridge theoretical foundations with real-world design insights, making it valuable for undergraduate students, postgraduate scholars, researchers, and faculty members working in RF and microwave engineering. Participants will gain a clear understanding of the complete RF PA design flow from specifications to hardware realization.
