ADL5320

Rev. 0 | Page 11 of 16

BASIC LAYOUT CONNECTIONS

The basic connections for operating the ADL5320 are shown in

Figure 26.

Table 5 lists the required matching components. Capacitors C1,

C2, C3, C4, and C7 are Murata GRM155 series (0402 size) and

Inductor L1 is a Coilcraft 0603CS series (0603 size). For all

frequency bands, the placement of C3 and C7 are critical. From

2300 MHz to 2700 MHz, the placement of C2 is also important.

Table 6 lists the recommended component placement for

various frequencies.

A 5 V dc bias is supplied through L1 which is connected to

supply decoupling capacitors are also required. The typical

current consumption for the ADL5320 is 110 mA.

SOLDERING INFORMATION AND RECOMMENDED

PCB LAND PATTERN

Figure 27 shows the recommended land pattern for the ADL5320.

To minimize thermal impedance, the exposed paddle on the

SOT-89 package underside is 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 the Application Note AN-772,

A Design and Manufacturing Guide for the Lead Frame Chip

Scale Package (LFCSP).
