LO1
High impedance modulator LO input. A shunt 56
resistor can be used
for matching. This pin is NOT internally DC blocked. An external block-
ing capacitor must be provided if the pin is connected to a device with
DC present. A DC path to ground (i.e. an inductor or resistor to ground)
is, however, acceptable at this pin. If a blocking capacitor is required, a
value of 1nF is recommended.
11
MOD OUT+
Balanced IF output port. If no filtering is required this pin can be con-
nected directly to the MIX IN+ pin. This pin is NOT DC blocked and car-
ries DC. A blocking capacitor of 1nF is needed when this pin is
connected to a DC path. An appropriate matching network may be
needed if an IF filter is used.
Same as pin 11, except complementary output.

MOD OUT-
GND1
See pin 11.
Ground connection for all baseband circuits, modulator and the IF
buffer amplifier. Keep traces physically short and connect immediately
to ground plane for best performance.
High impedance balanced input to the gain controlled IF stage. This pin
has an internal DC blocking capacitor. If no IF filter is needed, this pin
may be connected directly to MOD OUT-. If an IF filter is used, an exter-
nal shunt resistor to ground may be needed to provide correct matching
for the filter.
Same as pin 14, except complementary input.

See pin 14.
Ground connection for the limiting LO2 buffer amplifier. Keep traces
physically short and connect immediately to ground plane for best per-
formance.
