Function

Description
Baseband input to the Q mixer. This pin is DC-coupled. Maximum out-
put power is obtained when the input signal has a peak to peak ampli-
tude 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 maxi-
mum voltage on this pin (V
REF
+ peak modulation amplitude) should
never exceed 4.0V. See pin 1 for more details.

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

on this pin (V
