A good PCB layout for the RF081LAM2STR involves keeping the antenna away from other components, using a solid ground plane, and minimizing the length of the transmission lines. ROHM provides a recommended PCB layout in their application notes.
To ensure proper matching, use a network analyzer to measure the antenna's impedance and adjust the matching circuit accordingly. ROHM provides a matching circuit example in their application notes.
The maximum power handling of the RF081LAM2STR is 2W. Exceeding this power may cause damage to the device.
The RF081LAM2STR is rated for operation up to 85°C. However, it's recommended to derate the power handling at higher temperatures to ensure reliability.
Common issues with the RF081LAM2STR include impedance mismatch, power handling, and PCB layout issues. Use a network analyzer and oscilloscope to troubleshoot and identify the root cause of the issue.
