Figure 13: 5-Way Active Power Splitter with external MOSFET

Note:

Pin 22 must have 3.3 V maintained, even during power loss. This is normally accomplished by a battery backup. Upon

power loss, the FET load switch (SI 1869DH) cuts off power to the five output amplifiers, and puts the APS3625 in bypass

mode.
