VPS1 to VPS5

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).

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.

VOUT

Device Output. Single-ended RF output. Pin should be ac-coupled to the load. The output is ground

referenced.

19, 20,

IBBP, IBBN,

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.

EPAD

Exposed Pad. Connect to a ground plane via a low impedance path.
