A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF signal traces short and away from the DC power traces. Use a common mode choke or a ferrite bead to filter the DC power supply.
Optimize the output power and efficiency by adjusting the input impedance, output impedance, and biasing conditions. Use a load-pull analysis to find the optimal impedance matching. Adjust the bias voltage and current to achieve the desired output power and efficiency.
For high-power applications, a heat sink with a thermal conductivity of at least 1 W/m-K is recommended. Ensure good thermal contact between the device and the heat sink using a thermal interface material. Forced air cooling or liquid cooling can also be used for high-power applications.
Monitor the device temperature using a thermocouple or a thermal sensor. Implement a thermal shutdown circuit to turn off the device when the temperature exceeds a certain threshold. Ensure good thermal design and heat sinking to prevent thermal runaway and overheating.
Handle the device with an anti-static wrist strap or mat. Store the device in an anti-static bag or container. Use an ESD-protected workstation and follow proper ESD handling procedures to prevent damage to the device.
