CC2430 Channel Tx power variation?

Hi,

The power variation of 10dB across the channels means some faults in the board. I can say nothing about CC2430 but for CC2530 this value is declared (by the datasheet) at the 0.5...0.75 dB level. From my practice, in mass production, the boards with CC2530+CC2591 combination can show the variation of about 2 dB. As rule the 15th channel is the best and the 26th channel is the worst.

Anyhow, the 10 dB power drop means 3-fold distance decrease.

regards,

Ilya

According to this:

it has much more than 0.75db various across different channel. perhaps due to CC2591?

As follows from the curves you have pointed (fig.4.1.), the power variation across the channels is within 1 dB subject to the fixed supply votage and temperature.
