Power Amplifier The PA amplifies the RF output from the reciter and is available in 50 W
and 100 W models.
The 50 W model mounts vertically in the subrack, while the 100 W model
mounts horizontally as it has a wider heatsink. The 100 W PA is also fitted
with an airflow duct.
Both models are designed to operate on the 28 VDC output provided by the
PMU.
