Description
1
MIX LO
This pin is DC coupled and matched to 50 Ohms.
An off chip DC blocking capacitor is required.
2, 6 - 9,
11 - 17, 19 - 24
N/C
No connection. These pins may be connected to RF
ground. Performance will not be affected.
Power supply for the LO amplifier Bias resistor is
3
BIAS
required . Three external bypass capacitors are recom-
mended for optimum performance, as illustrated in the
application circuit.
4
GND
Backside of package has exposed metal ground
paddle that must also be connected to ground.
This pin is DC coupled and matched to 50 Ohms from
5
LO
0.8 to 1.2 GHz. An off chip DC blocking capacitor is
required.
This pin is DC coupled. For applications not requiring
operation to DC, this port should be DC blocked
externally using a series capacitor whose value has
10
IF
been chosen to pass the necessary IF frequency
range. For operation to DC, this pin must not source/
sink more than 18 mA of current or die non-function
and possible die failure will result.

This pin is DC coupled
and matched to 50 Ohms.
