UHF PCB/SCHEMATICS/PARTS LISTS
1.0 Allocation of Schematics and Circuit Boards
1.1 Controller Circuits
The UHF circuits are contained on the printed circuit board (PCB) which also contains the Controller
circuits. This Chapter shows the schematics for the UHF 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 UHF circuit components. The UHF schematics and the
related PCB and parts list are shown in the tables below.
