CC2590: RF tune-up tolerance FCC

Part Number: CC2590
Other Parts Discussed in Thread: CC2591, CC2592

Hi,

for FCC approval, we need to know the tune-up tolerance of CC2590. Unfortunately there is no related information on the data sheet. 

Anybody?

Thank you in advance!

Best regards,
Markus

    Hi,

    Please refer to Regulatory Requirements on SWRA308 (for CC2591). I guess the same applies to CC2590 also.

    If it is new design, better to use CC2592.

    Thanks,

    Hi,
    I checked AN086 (www.ti.com/lit/an/swra308a/swra308a.pdf) but it also says nothing regarding tune-up tolerance. Tune-up tolerance is, afak, the expected maximum output power variations of a product and is required to calculate human exposure for FCC. Seems the calculation changed recently, last year it was not requested.

    So there must be a statement from TI special for CC2590 (as it is product dependend).

    Btw. CC2592 is complete different in output power.

    Best regards,
    Markus

    Hi,

    It seems you are looking for Output Power variation. If that is so, please see the following table from the CC2590 data sheet.

    Thanks,
