APPLICATIONS INFORMATION

BASIC LAYOUT CONNECTIONS

The basic connections for operating the ADL5320 are shown in

Figure 34. Table 6 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 7 lists the recommended component

placement for various frequencies.

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

decoupling capacitors are also required. The typical current

consumption for the ADL5320 is 110 mA.
