Figure 3: PA Module Showing Input Launch

Board and PA Pallet With Connectors

Figure 3 shows part of the interface board, and details of the PA pallet and input launch boards, which sit on

top of the remainder of the interface board. RF enters the PA pallet via the input launch board. Connector J6 on

the interface board gets its RF input signal from edge connector J3-C and connects vertically to connector J2

of the input launch board. The center conductor of J2 connects to E1, the RF input of the PA pallet. J1, the 20

pin control connector of the PA pallet, connects vertically to J1 of the interface board. The interface board

supplies +50Vdc to the PA pallet via E1, through the hole in the PA pallet circuit board.
