Description
Input Common Pins. Connect to ground plane via a low impedance path.
COM1, COM2,
Positive Supply Voltage Pins. All pins should be connected to the same supply (V
S
). 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).
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.
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.
Device Output. Single-ended, 50 Ω internally biased RF output. Pin must be ac-coupled to the load.
Connect to ground plane via a low impedance path.
