Nijmegen, The Netherlands, April 30, 2025 – Ampleon today announced the release of the ART1K9FH, a new 50 V / 55 V RF LDMOS transistor, delivering up to 1900 W of output power. Designed for operation under demanding conditions, this device sets new benchmarks for ruggedness and reliability in industrial, medical, and scientific applications where equipment must withstand severe load mismatches.
Built on Ampleon’s proprietary Advanced Rugged Technology (ART) platform, the ART1K9FH operates up to 500 MHz and is capable of withstanding load mismatches up to 65:1 VSWR. It is housed in a SOT539A air-cavity ceramic package that supports efficient heat dissipation and long-term device stability. Target applications include plasma generators, CO₂ laser drivers, industrial and medical RF heating systems, particle accelerators, as well as FM and VHF broadcast transmitters.
The ART1K9FH combines high ruggedness with low thermal resistance and can deliver maximum output power from a standard 50 V supply. It is well suited for high-power solid-state amplifier designs that require compact, efficient, and robust RF building blocks.
"Many customers in industrial and medical markets are constrained by 50 V / 55 V DC power supply limits. The ART1K9FH provides an ideal solution, delivering nearly 2 kW of RF output power from a single SOT539 footprint, combined with best-in-class ruggedness and reliability," said Houssem Schuick, Senior Director Product Marketing Management at Ampleon. "Building on decades of experience in developing the industry's most powerful and reliable ruggedized RF power solutions, Ampleon continues to drive performance, reliability, and design flexibility for demanding RF applications."
The ART1K9FH is in production and backed by Ampleon’s 15-year product longevity commitment. Samples and evaluation boards are available through Ampleon’s global sales network and authorized distributors.
