Front panel dimensions are 5.585”(W) x 5.055”(H). The full length of PA does not exceed 8.2”.
The PA contains two PCB assemblies: the Main Board Assembly and the Control Board Assembly.
The Main Board is placed inside the shielded compartment and is bolted directly to the heatsink to
facilitate cooling.
The Main Board contains RF. The Control Board includes the LEDs, power controlling potentiometer, a
fan voltage regulator and the DC supply connector to the Main Board. The control, monitoring and
supply lines between the Main Board Assembly and the Control Board Assembly are connected through
an 8-pin connector.
