HIGH IP3 RFIC DUAL

DOWNCONVERTER, 1.7 - 2.2 GHz

v01.0704

Pin Number

Function

Description

Interface Schematic

1, 7

RF1, RF2

These pins are DC coupled and matched to 50 Ohms

from 1.7 - 2.2 GHz.

2, 4, 6, 8, 10, 12,

14, 16, 18, 20, 22,

24, 26, 28

GND

Backside of package has exposed metal ground slug

that must also be connected to ground.

3

Vdd

Power supply for the second stage LO amplifier. One

external bypass capacitor (1,000 pF) is required.

5, 15, 19

N/C

No connection. These pins may be connected to RF

ground. Performance will not be affected.

9, 27

MIX IF2,

MIX IF1

IF output from the mixers. This pin is DC coupled to

the mixer. A low pass filter and blocking capacitor are

required between mixer IF port and IF amplifier.

(See application circuit).

11, 25

AMP IF2,

AMP IF1

Inputs to the IF amplifiers. A low pass filter and blocking

capacitor are required between mixer IF port and IF

amplifier. (See application circuit).

13, 23

IF2, IF1

Outputs of the IF amplifiers and bias ports for the IF

amplifiers. A pull up inductor, resistor, and bypass

capacitors are required. (See application circuit).

17

LO

This pin is AC coupled and matched to 50 Ohms from

1.7 to 2.2 GHz.

21

Vdd LO

Bias voltage for the first stage of the LO amplifier. A pull

up inductor, resistor, and bypass capacitors are required.

(See application circuit).
