RF Power Amplifiers for EMC Radiated Immunity: Specifications, Architectures, and Smart Selection

About this event

This presentation provides a comprehensive overview of RF power amplifiers used in Electromagnetic Compatibility (EMC) testing, with a particular focus on their role in radiated immunity applications. It begins with an introduction to EMC testing and the importance of reliable, broadband RF power amplification for achieving the required test field strengths. Key amplifier specifications, including frequency range, output power, gain, efficiency, linearity, harmonic performance, VSWR, and ruggedness, will be discussed, followed by an overview of common broadband amplifier architectures and amplifier technologies used in EMC test systems. The presentation will highlight the importance of amplifier linearity and its critical role in maintaining signal integrity while minimizing unwanted distortion and harmonics during high-power operation. Practical considerations for selecting an EMC amplifier, including frequency coverage, power requirements, load conditions, system configuration, and applicable test-standard requirements will also be addressed.
