From kW to MW: powering the future of particle acceleration with solid-state technology

Offering a rugged, high-efficiency RF power transistor portfolio of GaN and LDMOS RF power transistors for CW and pulsed particle accelerator applications

The transition to solid-state power amplifiers (SSPAs) is reshaping RF power systems in large scientific facilities. Where feasible, replacing tube-based systems with modern solid-state solutions from 50 MHz to 6 GHz enhances efficiency, reliability, and longevity.

Achieving the power levels of vacuum tube technology with SSPAs requires the precise combination of multiple solid-state devices. At Ampleon, we develop the industry’s most efficient and rugged RF power transistors, working closely with national laboratories, research institutions, medical pioneers, and industrial leaders to help design and build cutting-edge RF amplifier systems.

Our expertise in extremely ruggedized solutions ensures that our continuous-wave (CW) solid-state devices can withstand harsh mismatch conditions and RF on/off cycling, which is often critical for long-term system reliability.

Whether your project requires 1 kW or several megawatts, Ampleon is your trusted design and technology partner for high-performance RF amplification.
