Input Common Pins. Connect to ground plane via a low impedance path.
No Connect. These pins can be left open or tied to ground
Description
Output Disable. A logic high on this pin disables the RF output (Pin 16). Connecting this pin to
ground or leaving it floating enable the RF output.
Local Oscillator Input. 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.
Differential In-Phase and Quadrature Baseband Inputs. These high impedance inputs should be dc-
biased to 500 mV (ADL5375-05) or 1.5 V (ADL5375-15). Nominal characterized ac signal swing is 500
mV p-p on each pin. This results in a differential drive of 1 V p-p with a 500 mV dc bias. These inputs
are not self-biased and must be externally biased.
Device Output. Single-ended, 50 Ω internally biased RF output. AC-couple to the output load.
Positive Supply Voltage Pins. All pins should be connected to the same supply (V
adequate external bypassing, connect 0.1 μF and 100 pF capacitors between each pin and ground.
Exposed Paddle. Connect to ground plan via a low impedance path.
