Function
I SIG
Description
Baseband input to the I mixer. This pin is DC-coupled. Maximum output
power is obtained when the input signal has a peak to peak amplitude
of 2V. The recommended DC level for this pin is 3.0V. The peak mini-
mum voltage on this pin (V
REF
- peak modulation amplitude) should
never drop below 2.0V. The peak maximum voltage on this pin (V
REF
+
peak modulation amplitude) should never exceed 4.0V.

NOTE:
The values of R and C depend on the minimum
baseband frequency (i.e., the cutoff frequency of
this high pass filter should be lower than the
lowest frequency component in the I/Q spectrum).
