Pin Configuration and Function Descriptions

• COM1 to COM4: Input Common Pins. Connect to ground plane via a low impedance path.
• 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.
• LOIP, LOIN: 50 Ω Single-Ended Local Oscillator Input. Internally dc-biased. Pins must be ac-coupled.
• VOUT: Device Output. Single-ended RF output. Pin should be ac-coupled to the load.
• 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.
