Function

Description

interface schematic

1

Mix LO

This pin is DC coupled and matched to 50 Ohms.

An off chip DC blocking capacitor is required.

2, 6 - 9,

11 - 17, 19 - 24

N/C

No connection. These pins may be connected to rF

ground. Performance will not be affected.

3

BiAs

Power supply for the LO amplifier , a Bias resistor is

required . Three external bypass capacitors are recom-

mended for optimum performance, as illustrated in the

application circuit.

4

GND

Backside of package has exposed metal ground

paddle that must also be connected to ground.

5

LO

This pin is DC coupled and matched to 50 Ohms.

An off chip DC blocking capacitor is required.

10

iF

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 18 mA of current or die non-function

and possible die failure will result.

18

rF

This pin is DC coupled and

matched to 50 Ohms.
