Q SIG
Baseband input to the Q mixer. This pin is DC-coupled. Maximum output
power is obtained when the input signal has a peak to peak amplitude of
2V; for highly linear operation, the input signal (and output power) must be
reduced appropriately. The recommended DC level for this pin is 3.0V. The
peak minimum 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 4.0 V. See pin 1
for more details.

I SIG
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; for highly linear operation, the input signal (and output power) must be
reduced appropriately. The recommended DC level for this pin is 3.0V. The
peak minimum 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 4.0 V. See pin 1
for more details.
