Note 5: Recommended functional range, not production tested. Operation outside this range is possible, but with degraded perfor-
mance of some parameters.
Note 6: All limits include external component losses of components, PCB, and connectors.
Note 7: It is advisable not to operate the I and Q inputs continuously above 2.5V
P-P
differential.
Note 8: Guaranteedbydesignandcharacterization.
Note 9: Single-carrier WCDMA peak-to-average ratio of 10.5dB for 0.1% complementary cumulative distribution function.
Note 10:Nobasebanddriveinput.Measuredwiththebasebandinputsterminatedin50ΩtoGND.Atlow-outputpowerlevels,the
output noise density is equal to the thermal noise floor.
Note 11:ItisadvisablenottooperatetheRFinputcontinuouslyabove+17dBm.
