Forum Post: RE: What is best or resonable setting for data rate of 125Kbps and 62.5Kbps for CC2500 of eZ430-RF2500-SEH?

Tan, 

The output PA is actually supplied by the internal LDO inside the CC2500, there is no substantial change in performance while changing the input supply voltage from 2.0 to 3.6V.
