noise floor which will degrade the SNDR of the re-
ceive signal.
The same is true of the transmit signal. If the signal is
undistorted it will show up out of band in the receive
path and will not degrade SNDR. However, if the
Table 2. Chip Performance Specifications
4.2 Power Amplifier Performance
The power amplifier must be specified with all of the
external components in the application diagram.
Without these components the amplifier will not func-
tion correctly. Specifications that are measured at the
chip are specified as such in the comments.

transmit signal is distorted by the cross-talk mecha-
nism it will show up in the receive band and could re-
duce the SNDR.
The cross-talk numbers are specified from output to
output under maximum gain conditions.
Table 3 contains the conditions over which the spec-
ifications in Table 4 apply. The limits on the specifica-
tions in Table
specified in Table 3. The nominal values of the spec-
ification occur at the nominal value of all of the condi-
tions in Table 3 unless otherwise specified.
