Figure 1.3 below shows the configuration for a typical 100 W base station.
The PMU occupies slots 5 and 6, with the PA directly beside it in slots 3
and 4. The reciter occupies slot 1. Unlike the 50W PAs, the 100W PA is
mounted horizontally with the heatsink facing upwards. It is also fitted with
an airflow duct to channel the airflow from the cooling fan through the
heatsink fins.
