16 to 19, 22, 24,

27 to 30, 32, 34 to 36

GND

Ground. Connect to ground plane via a low impedance path.

3, 13, 15, 31, 33

VPS1, VPS2, VPS3,

VPS4, VPS5

Positive Supply Voltage. All pins should be connected to the same supply. To ensure

adequate external bypassing, connect 0.1 μF capacitors between each pin and ground.

4, 6

LOIP, LOIN

Local Oscillator Input. 50 Ω single-ended local oscillator input. Pins must be ac-coupled.

AC-couple LOIN to ground and drive LO through LOIP.

20, 21, 25, 26

IBBP, IBBN, QBBN, QBBP

Baseband Inputs. Differential in-phase and quadrature baseband inputs. These high

impedance inputs must be dc-biased to approximately 1.5 V dc. These inputs are not

self-biased and must be externally biased.

23

VOUT

RF Output. Single-ended, 50 Ω, internally biased RF output. Pin must be ac-coupled to

the load.
