Abstract
Wireless systems are increasingly used to address some of the world’s most pressing societal challenges, but deployment of these solutions also introduces specific technical challenges. A critical component in many wireless communication and sensing systems is the power amplifier (PA). Given the broad range of applications, there is a growing need for PAs that can operate across various power levels, support multiple frequency bands, offer wider bandwidths, and maintain high power efficiency. This has significantly expanded the role and design responsibilities of PA engineers.
In modern wireless communication systems, design specifications for power amplifiers now extend beyond their traditional input and output ports to encompass broader system-level requirements. This workshop will bring together insights from industry and academic leaders on key system-level considerations, including cellular network infrastructure, non-terrestrial communication link simulation, and innovative PA designs that are pushing the boundaries of wireless system performance.

Hands-On Workshop for Signal Analyzing Measurement
Organizers: Herrmann Boss, Paul Peterson, Rohde&Schwarz
Room:
Abstract
This workshop will provide a hands-on learning experience in generating and measuring complex modulated signals. Participants will gain practical skills in utilizing common measurement techniques with the use of spectrum analyzers and vector signal generators. Through interactive sessions, attendees will explore the generation of various modulation schemes such as amplitude and frequency modulation, phase shift keying (PSK), and quadrature amplitude modulation (QAM). They will also learn to analyze the resulting signals, measure key parameters like carrier frequency, modulation index, and signal-to-noise ratio (SNR), and identify potential impairments. By the end of the workshop, participants will have a solid understanding of the fundamental principles of signal modulation and the ability to apply these techniques effectively in their research or engineering projects.
