Description
This pin is DC coupled and matched to 50 Ohms from

MIX LO
1.6 to 3.0 GHz. An off chip DC blocking capacitor is
required.

ground. Performance will not be affected.
Power supply for the second stage LO amplifier. Three
external bypass capacitors are recommended for

optimum performance, as illustrated in the application
circuit.
Backside of package has exposed metal ground

LO
1.6 to 3.0 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 exter-
nally using a series capacitor whose value has been
10
IF
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
