GND

These pins and package bottom must be

connect to RF/DC ground.

3RF

This pin is AC coupled and matched

to 50 Ohms from 6 - 20 GHz

9IF

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 been chosen to pass the necessary IF

frequency range. For operation to DC, this pin must not source/

sink more than 2 mA of current or die non-function and possible

die failure will result.

LO

This pin is AC coupled and matched

to 50 Ohms from 6 - 20 GHz
