Pin Number

Function

Description

Interface Schematic

1MIX 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.

3BIAS

Power supply for the LO amplifier. Three external

bypass capacitors are recommended for optimum per-

formance, as illustrated in the application circuit.

4GND

Backside of package has exposed metal ground

paddle that must also be connected to ground.

5LO

This pin is DC coupled and matched to 50 Ohms from

1.7 to 4.0 GHz. 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 exter-

nally 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.
