A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces short and away from the digital lines. Use a 50-ohm microstrip line for the RF output.
Use the lowest possible supply voltage (1.8V) and reduce the operating frequency. Disable the internal voltage regulator if an external regulator is used. Use the power-down mode when not transmitting.
The maximum operating temperature for the 854651 is 125°C. However, it's recommended to operate within 85°C for optimal performance and reliability.
Yes, but impedance matching is required to ensure optimal performance. Use a pi-network or a series LC circuit to match the impedance.
Use a spectrum analyzer to check the output frequency and power. Verify the input voltage and current. Check the PCB layout for any issues. Consult the datasheet and application notes for troubleshooting guides.
