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

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.

VOUT
RF Output. Single-ended, 50 Ω, internally biased RF output. Pin must be ac-coupled to
the load.
Exposed Paddle. Connect to ground plane via a low impedance path.
