N/C

No connection. These pins may be connected to

rF ground. Performance will not be affected.

3

rF

This pin is DC coupled and

matched to 50 Ohms.

7

iFiN

This pin is matched to 50 Ohms with a 56nH inductor to

ground. see Application Circuit.

9

CAP

AC ground. An external capacitor of 0.01 µF to ground is

required for low frequency bypassing. see application circuit

for further details.

10

MixiF

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

part non-function and possible part failure will result.

12

iFOUT

This pin is AC coupled and

matched to 50 Ohms.

13

VddiF

Power supply for iF amplifier. Choke

inductor and bypass capacitor are required.

see application circuit.

16

MixLO

This pin is DC coupled and matched to 50 Ohms.

An off chip DC blocking capacitor is required.

17

GND

Backside of package has exposed metal ground

paddle that must also be connected to ground.

18

VccLO

Power supply and rF Output of the LO

amplifier. Three external bypass capacitors

are recommended for optimum performance,

as illustrated in the application circuit.
