capacitors (10 pF & 10,000 pF) and an external inductor (1.8
nH) are required.

GND
Ground: Pin must connect to RF ground.
IF Port: This pin is DC coupled. For applications not requiring
operation to DC, this port should be DC blocked externally

IF Port
using a series capacitor whose value has been chosen to pass
the necessary IF frequency range. For operation to DC, this pin
must not source/sink more than 3mA of current or die non-func-
tion and possible die failure will result.

RF Port
RF Port: This pin is AC coupled and matched to 50 Ohm from
3.0 - 3.8 GHz.

LO Port
LO Port: This pin is AC coupled and matched to 50 Ohm from
3.0 - 3.8 GHz
