ADL5606 MATCHING

The RF input and output of the ADL5606 can be easily

matched to 50 Ω with at most one external component and the

microstrip line used as an inductor. Table 6 lists the required

matching component values. Capacitors CIN and COUT are Murata

GRM155 series (0402 size).

For all frequency tuning bands, the placement of CIN and COUT

is critical. Table 7 lists the recommended component spacing

for the various frequency tuning bands. The component

spacing is referenced from the center of the component to the

edge of the package.

Figure 33 to Figure 35 show the matching networks.
