Description

Interface Schematic

1RF

This pad is DC coupled

and matched to 50 Ohms.

2 (5)

IF2

This pad is DC coupled. For applications not requir-

ing 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 pad must not

source/sink more than 3mA of current or die non-

function and possible die failure will result. Pads 5

and 6 are alternate IF ports.

3 (6)

IF1

4LO

This pad is DC coupled

and matched to 50 Ohms.

GND

The backside of the die must be connected

to RF/DC ground.
