Description

1, 2, 3

NC

No Connect. Leave these pins open or tie them to ground.

4, 5, 6, 15,

16, 19, 20

COM1, COM2,

COM3

Power Supply Common Pins. Connect COM1, COM2, and COM3 to a ground plane via a low impedance path.

7

VOUT

Device Output. Single-ended, 50 Ω internally biased RF/IF output; pin must be ac-coupled to the load.

8, 9, 11, 23,

24

VPS1, VPS2,

VPS3

Power Supply Pins. Decouple each pin with a 0.1 μF capacitor; Pin 8 and Pin 9 can share a single capacitor,

as can Pin 23 and Pin 24. Connect all pins to the same supply.

10

TEMP

Temperature Sensor Output. Provides dc voltage proportional to die temperature. Slope is 4.6 mV/°C

12

ENBL

Device Enable. Shuts device down when grounded and enables device when pulled to supply voltage.

13, 14,

17, 18

IBBP, IBBN,

QBBN, QBBP

Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs must be externally dc-

biased to 500 mV dc and driven from a low impedance source. Nominal characterized ac signal swing is 700 mV

p-p on each pin (150 mV to 850 mV). This results in a differential drive of 1.4 V p-p with a 500 mV dc bias.

21

LOIP

Single-Ended Two-Times Local Oscillator Input. This input is internally biased and must be ac-coupled to

the LO source.

22

LOIN

Common for LO Input. Must be ac-coupled to ground through a low impedance path.

EPAD

Exposed Pad. Solder the exposed pad to a low impedance ground plane.
