Sumitomo Electric Device Innovations USA At IMS 2025

Sumitomo Electric Device Innovations USA (SEDU) announced it will showcase its High Power GaN-HEMTs for ISM-band (Industrial, Scientific, and Medical), microwave heating, and continuous-wave (CW) applications. The featured ES/SGN2425-300P device offers high power, high efficiency, easy matching, and consistent performance for 2.4–2.5 GHz high-power uses with 50V operation.

High Power GaN-HEMTs are increasingly replacing traditional technologies like magnetrons and LDMOS in these applications due to their superior efficiency (up to 70%), reliability, and ability to deliver precise, uniform heating through phase control. They are widely used in industrial ovens, medical equipment, plasma generation, and RF lighting, where their high-power handling and long operational life provide significant advantages over legacy solutions.

FEATURES:

  • High Peak Power: 300W CW
  • 3-stage Total Efficiency: 74%
  • Total Power Gain: 50dB
  • All 50V VDD Operations
  • Easy Matching: Pre-matched for 2.5GHz (HPA)
  • Small Size Package

Key Advantages of GaN-HEMTs:

  • High Power Density: 10–20 W/mm power density in CW/pulsed modes enables compact, high-power systems for industrial heating and wireless power transfer.
  • Efficiency: Achieves 77% typ. drain efficiency at ISM frequencies (e.g., 2.45 GHz), rivaling magnetrons while offering precise control.
  • Reliability and Thermal Performance: 10+ years operational lifespan, far exceeding magnetrons (1–3 years), reducing maintenance costs.
  • Phase Coherence and Control: Unlike magnetrons, GaN-based SSPAs (Solid-State Power Amplifiers) enable phase-coherent power delivery, allowing beamforming, power steering, and uniform heating in microwave cavities.
  • Scalability and Flexibility: Combines multiple GaN amplifiers to reach kW-level power, overcoming single-device limits of magnetrons (~6 kW) or LDMOS (~250 W).
  • Cost: Higher up-front cost but lower total ownership cost due to longevity, efficiency, and control.
