Description

1, 2, 5, 6, 8, 12,

14, 17, 19, 23

GND

Device Common (DC Ground).

3, 4

LOIP, LOIN

Differential LO Input Terminal. Internally matched to 50 Ω. Must be ac-coupled.

7, 24

VPLO

Positive Supply Voltage for LO System.

9

ENBL

Device Enable. Pull high to disable the device; pull low to enable.

10

VSET

Input IP3 Bias Adjustment. The voltage presented to the VSET pin sets the internal bias of the mixer core

and allows for adaptive control of the input IP3 and NF characteristics of the mixer core.

11

DETO

Detector Output. The DETO pin should be loaded with a capacitor to ground. The developed voltage is

proportional to the rms input level. When the DETO output voltage is connected to the VSET input pin,

the part auto biases and increases input IP3 performance when presented with large signal input levels.

13

VPDT

Positive Supply Voltage for Detector.

15, 16

RFIN, RFIP

Differential RF Input Terminal. Internally matched to 50 Ω differential input impedance. Must be

ac-coupled.

18

VPRF

Positive Supply Voltage for RF Input System.

20, 21

IFOP, IFON

Differential IF Output Terminal. Bias must be applied through pull-up choke inductors or the center tap

of the IF transformer.

22

NC

Not Connected.

EPAD

The exposed paddle must be soldered to ground.
