Number

Name

Description

1

RF_IN

RF input. Matched to 50 ohms. DO NOT apply DC to this pin.

2

RF_IN_rtn RF input transformer ground return. Ground this pin.

3, 4, 6, 8, 9,

10, 14

NC

Not connected.

5

GND

Ground this pin.

7, 18, 20, 24

VCC

Power Supply. Bypass to ground with appropriate capacitors as close as possible to pin

11

Gain_Select1 Gain select control pin, includes internal pull-down resistor. See gain select truth table for desired setting

12

Gain_Select2 Gain select control pin, includes internal pull-down resistor. See gain select truth table for desired setting

13

IFRef_Bias Connect recommended resistor value from this pin to ground to set the IF amplifier reference current

15

LO_IN_rtn LO input transformer ground return. Ground this pin.

16

LO_IN

Local Oscillator (LO) input. Matched to 50 ohms. DO NOT apply DC to this pin.

17

LO_ADJ

Connect zero ohm resistor to ground here for best performance

19

STBY

Standby Input (Low/Open = Power ON, High = Power OFF). Includes internal pull-down resistor

21, 22

IF_OUT-,

IF_OUT+

Mixer Differential IF Output. Connect pull-up inductors from each of these pins to VCC (see the Typical

Application Circuit)

23

IF_Bias

Connect the specified resistor from this pin to ground to set the bias for the Main IF amplifier

— EP

Exposed Pad. Internally connected to GND. Solder this exposed pad to a PCB pad that uses multiple ground

vias to provide heat transfer out of the device into the PCB ground planes. These multiple via grounds are

also required to achieve the specified RF performance
