We performed FCC pre-compliance testing today with our design that contains CC2651RKP. Our design supports a maximum output power of +8.5dBm. At this level, we are failing 15.205 by 17dB at 2483.5 MHz.
We also looked at a LP-CC2651P3 set to +20dBm output. It is failing by 26dB. We then reduced the output of the LP_CC2651P3 and found we needed to set the output to -8dBm or lower to pass. This output level makes channel 26 unusable from a practical perspective.
According to the "TI 15.4 Stack User's Guide", the max output on channel 26 for LP_CC2651R3SIPA is +1dBm. There is no entry listed for LP_CC2651P3. Is it expected that the channel 26 max output for LP_CC2651P3 would be -8dBm?
