4 SPECIFICATIONS
4.2 Physical Configuration
The power amplifier is designed to fit in an RF Technology sub-rack within a 19" rack
frame. The installed height is 4 Rack Units (RU), or 178mm, and the depth is 350mm.
The amplifier is 95.25mm or three Eclipse units wide. The amplifier uses an extruded
aluminium heat sink with vertical fins. Heatsink temperature rise is typically 20C at
50W output.
