1, 2, 3
NC
No Connect. Leave these pins open or tie them to ground.
4, 5, 6, 15,

COM1, COM2, Power Supply Common Pins. Connect COM1, COM2, and COM3 to a ground plane via a low impedance
COM3
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, VPS1, VPS2,
24
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,

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. Soldered the exposed pad to a low impedance ground plane.
