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.
