Positive Supply Voltage Pins. All pins should be connected to the same supply (VS). To ensure adequate
external bypassing, connect 0.1 µF capacitors between each pin and ground. Adjacent power supply pins of
the same name can share one capacitor (see Figure 25).

23, 24 QBBN, QBBP
Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs must be dc-biased to
500 mV dc, and must be driven from a low impedance source. Nominal characterized ac signal swing is
700 mV p-p on each pin. This results in a differential drive of 1.4 V p-p with a 500 mV dc bias. These inputs are
not self-biased and must be externally biased.
8, 9
LOIP, LOIN
50 Ω Single-Ended Local Oscillator Input. Internally dc-biased. Pins must be ac-coupled. AC-couple LOIN to
ground and drive LO through LOIP.
13
VOUT
Device Output. Single-ended, 50 Ω internally biased RF output. Pin must be ac-coupled to the load.
EPAD
Exposed Pad. Connect to a ground plane via a low impedance path.
