Description
Input Common Pins. Connect to ground plane via a low impedance path.
Positive Supply Voltage Pins. All pins should be connected to the same supply (V
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).
50 Ω Differential Local Oscillator Input. Internally dc-biased. Pins must be ac-coupled. Refer to
Figure 8 for LO input impedance.
Device Output. Single-ended RF output. Pin should be ac-coupled to the load. The output is
ground referenced.
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.
Connect to ground plane via a low impedance path.
