placement of Capacitors C22, C26, and C28 is critical. Table 9
lists the recommended component spacing of C22, C26, and
C28 for the various frequencies. The component spacing is
referenced from the center of the component to the edge of the
package. Figure 59 to Figure 62 show the graphical represent-
ation of the matching network.
