Each IQ baseband input has a 180  differential input impedance allowing straightforward
matching, from the DAC output through the baseband filter. The device allows operation
with IQ input common-mode voltages between 0.25 V and 3.3 V allowing direct
connection to a broad family of DACs. The LO and RF ports provide broadband 50 
termination to RF source and loads.
The chip can be placed in inactive mode (see
Table 3.
The modulator can be placed into inactive mode by the voltage level at power-up disable
pin (pin 1, POFF_P). The time required to pass between active and low-current states is
less than 1 s.
The shutdown feature of IQ modulator during switching does not induce any unlock of the
LO synthesizer in base station application thanks to the low impedance variation of the LO
input.
