CC2592: CC2592 gain tolerances

Filip Reenaers
Prodigy 100 points
Part Number: CC2592
Other Parts Discussed in Thread: CC2540

CC2592 got a typical gain of 24 dB.  For input power of 0 dBm, the output is 20.3 dBm.  Hence already in compression.

The tolerance on the gain values in the datasheet are as follows :

Questions :

1. Are those values +/- values?  Hence 3.8 dB is +/- 3.8 dB?

2.  Have you got gain tolerance curves for power supply 3.0V, 3.3 and 3.6 V?

Kind regards

F.R.

    I'm looking at the characterization report and from what I can see:
    - Variation over frequency: The number is the delta between the min and max average output power that are measured over frequency.
    - Variation over supply: The number is the delta between the min and max average output power that are measured over supply voltage
    - Variation over supply: The number is the delta between the min and max average output power that are measured over temperature

    Do you mean gain or do you mean variation of output power vs supply voltage?

    So this means those figures are reflecting the max tolerance over the indicated variation parameter, not the double value.  Thanks

    I mean the graphs you are referring to in the characterization report....similar to the curves in the CC2540 datasheet.  See example below.

    The data I could find is only measured for -40, 25 and 125. Values in dBm.
