N/C

No Connection. These pins may be connected to

RF ground without affecting performance.

3, 6

LO1, LO2

LO Port: This pin is DC coupled and matched to

50 Ohms.

12, 29

IF2, IF1

IF Port: This pin is DC coupled. For applications not requiring

operation to DC, this port should be DC blocked externally

using a series capacitor whose values has been chosen to

pass the necessary IF frequency range. For operation to DC,

this pin must not source/sink more than 4mA of current or die

non-function and possible die failure will result.

RF2, RF1

RF Port: This pin is DC coupled and matched to

50 Ohms.
