ADL5375
BASIC CONNECTIONS
Figure 54 shows the basic connections for the ADL5375.
POWER SUPPLY AND GROUNDING
Pin VPS1 and Pin VPS2 should be connected to the same 5 V
source. Each pin should be decoupled with a 100 pF and
0.1 μF capacitor. These capacitors should be located as close
as possible to the device. The power supply can range between
4.75 V and 5.25 V.
The ten COMM pins should be tied to the same ground plane
through low impedance paths.
The exposed paddle on the underside of the package should also
be soldered to a ground plane with low thermal and electrical
impedance. If the ground plane spans multiple layers on the
circuit board, they should be stitched together with nine vias
under the exposed paddle as illustrated in the Evaluation Board
section. The AN-772 application note discusses the thermal and
electrical grounding of the LFCSP (QFN) package in detail.
BASEBAND INPUTS
The baseband inputs (IBBP, IBBN, QBBP, and QBBN) should be
driven from a differential source. The nominal drive level used
in the characterization of the ADL5375 is 1 V p-p differential
(or 500 mV p-p on each pin).

All the baseband inputs must be externally dc biased. The
recommended common-mode level is dependent on the
version of the ADL5375.

LO INPUT
The LO input is designed to be driven from a single-ended
source. The LO source is ac-coupled through a series capacitor
to the LOIP pin while the LOIN pin is ac-coupled to ground
through a second capacitor.
The typical LO drive level, which was used for the
characterization of the ADL5375, is 0 dBm.
Differential operation is also possible, in which case both sides
of the differential LO source should be ac-coupled through a
pair of series capacitors to the LOIP and LOIN pins.
RF OUTPUT
The RF output is available at the RFOUT pin (Pin 16), which can
drive a 50 Ω load. The internal balun provides a low dc path to
ground. In most situations, the RFOUT pin must be ac-coupled
to the load.
