Preliminary Technical Data
BASIC CONNECTIONS FOR OPERATION
The device’s seven power supply pins should be individually
decoupled using 1000 pF and 0.1 μF capacitors located as close
as possible to the device. In additional, internal decoupling
nodes (labeled DECL) should be decoupled with the capacitor
values shown.

The four IQ inputs should be driven with a bias level of 500
mV. A peak-to-peak differential swing on the I and Q inputs of
1 V (0.353 Vrms for a sinewave input) results in a single
sideband output power of +4 dBm. The I and Q inputs are
high impedance and should normally be terminated with
resistors to provide an appropriate match to the baseband filter
which immediately precedes the IQ modulator in the signal
chain.
