adl5602 Analog Devices, Inc., adl5602 Datasheet - Page 11

• Manufacturer Part Number: adl5602
• Description: 50 Mhz To 4.0 Ghz Rf/if Gain Block
• Manufacturer: Analog Devices, Inc.

BASIC CONNECTIONS
The basic connections for operating the ADL5602 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 ADL5602.
To minimize thermal impedance, the exposed paddle on the
package underside should be soldered down to a ground plane
along with Pin 2. If multiple ground layers exist, they should be
stitched together using vias. For more information on land
pattern design and layout, refer to AN-772 Application Note, A
Design and Manufacturing Guide for the Lead Frame Chip Scale
Package (LFCSP).
