ADL5535
BASIC CONNECTIONS
The basic connections for operating the ADL5535 are shown in
Figure 15. Recommended components are listed in Table 5. The
input and output should be ac-coupled with appropriately sized
capacitors (device characterization was performed with 0.1 μF
capacitors). A 5 V dc bias is supplied to the amplifier through
the bias inductor connected to RFOUT (Pin 3). The bias voltage
should be decoupled using a 1 μF capacitor, a 1.2 nF capacitor,
and a 68 pF capacitor.

SOLDERING INFORMATION AND RECOMMENDED
PCB LAND PATTERN
Figure 16 shows the recommended land pattern for the ADL5535.
To minimize thermal impedance, the exposed paddle on the
package underside, along with Pin 2, should be soldered to a
ground plane. If multiple ground layers exist, they should be
stitched together using vias. For more information about land
pattern design and layout, refer to the AN-772 Application
Note, A Design and Manufacturing Guide for the Lead Frame
Chip Scale Package (LFCSP).
