Qorvo provides a recommended PCB layout and thermal management guide in their application note AN-2171, which includes guidelines for thermal vias, heat sinks, and PCB stack-up to ensure optimal performance and thermal dissipation.
Qorvo offers a free online tool called Qorvo's GaN Device Model and S-Parameter Tool, which allows users to simulate and optimize the biasing and matching networks for their specific application. Additionally, Qorvo's application engineers can provide custom support and guidance.
While the datasheet specifies a maximum junction temperature of 150°C, the maximum operating temperature range for the QPA9842TR13 is typically limited by the package and PCB design. Qorvo recommends a maximum operating temperature of 125°C for most applications, but this can vary depending on the specific use case and design.
Qorvo recommends using a soft-start circuit to slowly ramp up the voltage and current during startup, ensuring the device is properly biased and turned on. This can be achieved using a simple RC circuit or a dedicated soft-start IC.
The QPA9842TR13 is a sensitive GaN device that requires proper ESD protection and handling. Qorvo recommends following standard ESD handling procedures, such as using wrist straps, anti-static bags, and ESD-safe workstations, to prevent damage during handling and assembly.
