8 Integrated Passive Component (IPC)

An Integrated Passive Component (IPC) is a matched-filter balun component specially designed or matched to the RF section. The IPC reduces the component count that saves space and reduces pick-and-place assembly costs. In addition, there is less risk of a poor RF layout with an IPC since the RF crosstalk is minimized. Table 8-1 lists the available IPC’s.
