A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use 50-ohm microstrip lines. Avoid vias and thermal pads under the device.
Use the Qorvo simulation models and design tools to optimize the component values and layout for the desired frequency band. Consider the device's S-parameters and impedance matching for optimal performance.
The QPA2628 can handle up to 33 dBm of input power. However, the maximum power handling may vary depending on the specific application and operating conditions. Consult the datasheet and application notes for more information.
Follow the recommended biasing scheme in the datasheet, using a voltage regulator and a current-limiting resistor. Ensure the voltage supply is stable and noise-free, and consider using a voltage regulator with a low dropout voltage.
Use a thermal pad or a heat sink to dissipate heat. Ensure good thermal conductivity between the device and the PCB. Consider using thermal interface materials and follow the recommended thermal design guidelines in the datasheet.
