LOWBAND PCB/SCHEMATICS/PARTS LIST
1.0 Allocation of Schematics and Circuit Boards
1.1 Controller Circuits
The Lowband circuits are contained on the printed circuit board (PCB) which also contains the
Controller circuits. This chapter shows the schematics for the Lowband circuits only, refer to the
Controller section for details of the related Controller circuits. The PCB component layouts and the
Parts Lists in this chapter show both the Controller and Lowband circuit components. The Lowband
schematics and the related PCB and parts list are shown in the Table below.
