App Note 011 Impact of Drain Voltage on GaN RF Transistors and Safe Operating Area (SOA) Analysis
While increasing the
drain voltage in GaN RF transistors can boost output power, it introduces
significant challenges related to thermal management, efficiency, and
reliability. Understanding the SOA and adhering to its constraints is crucial
for optimizing performance and
ensuringlong-term stability.
Proper design considerations, including thermal management and optimized
biasing, can help mitigate these issues and extend the operational lifespan of
GaN devices.
