We are using the CC1101 in a 400 MHz application. Our over the air bit rate is 68 Kbps.
TI supplies a typical value for receiver sensitivity for the CC1101 at various frequencies and bit rates. Can you give us some idea of how much variance we should expect to see around those typical values? Is the variance 1, 2, or 3 dB?
We've built a thousand prototypes of this receiver (CC1101 + discrete balun + SAW filter) and have pretty good mean, standard deviation and Cpk values for the run. We're now trying to ascertain how much of the variation we see is due to normal variation in the CC1101. We're also looking at the variation introduced by our other receiver circuitry as well (i.e. SAW insertion loss for instance). Any information regarding the Rx sensitivity variance we'd expect to see would be helpful.
Thanks,
Mark
