A 4-layer PCB with a solid ground plane and a separate power plane is recommended. The device should be placed near the center of the board, and the RF traces should be kept short and away from digital signals.
The device requires a single 3.3V power supply, and the recommended biasing is Vdd = 3.3V, Vgg = 1.5V, and Vbb = 1.5V. Ensure that the power supply is clean and well-regulated to prevent noise and oscillations.
The device is rated for operation from -40°C to +85°C, but the optimal operating range is from 0°C to +70°C for best performance and reliability.
Check the PCB layout for any errors or inconsistencies, ensure proper biasing and power supply, and verify that the device is properly matched to the antenna or load. Use a spectrum analyzer to identify any spurious signals or oscillations.
Yes, the device can be used in a push-pull configuration to achieve higher power output, but this requires careful design and layout to ensure proper impedance matching and to prevent oscillations.
