LP-EM-CC1354P10: Transmit power issue

Part Number: LP-EM-CC1354P10
Other Parts Discussed in Thread: CC1354P10

Hi,

I am currently working with the CC1354P10 LaunchPad, configured to operate at 868 MHz with a transmit power setting of +14 dBm. However, when measuring the output using a spectrum analyzer, the observed power is significantly lower at around –3.18 dBm.

After changing the configured transmit power to +12 dBm, the measured output further decreases to approximately –4.37 dBm.

I would like to understand why the measured transmit power is much lower than the configured value and how the output power can be improved.

Thank you for your assistance.

Best regards,
Anbu
