Best 100W Power Amplifier Modules (Class D & GaN)

The 100W power amplifier module market is currently seeing a massive shift toward Class D and GaN (Gallium Nitride) technologies, which now dominate consumer interest due to their high efficiency (>90%) and compact size. The global market is projected to grow to $132.65 billion by 2034, fueled by AI-driven DSP integration and automotive infotainment needs.

I have compiled a detailed report covering market size projections, technical comparisons between Class D and Class AB architectures, and a shortlist of top-performing products and suppliers. Key findings show that Class D modules currently command 15x more market interest than traditional Class AB counterparts, primarily due to their superior heat management and integrated "smart" features like Bluetooth 5.0 and DSP.
