Power Amplifier
The PA amplifies the RF output from the reciter and is available in 50W
and 100W models.
The 50W model mounts vertically in the subrack, while the 100W model
mounts horizontally, as it has a wider heatsink. The 100W PA is also fitted
with an airflow duct.
Both models are designed to operate on the 28VDC output provided by the
PMU.
Power Management
Unit
The PMU provides the 28VDC
power supply for the modules in the
subrack. It can operate on
120/230VAC 50/60Hz nominal, and
12, 24 or 48VDC nominal. The input
voltage can be AC, DC, or both AC
and DC, depending on the model. The
PMU also has an auxiliary DC output
of 13.65VDC, 27.3VDC, or
54.6VDC, depending on the model.
Notice From December 2020, new PMUs have different CPUs and
firmware from previous versions. The new PMU design is functionally
identical to the previous hardware version 1.00. The PMU reports ver-
sion 3.16 when operating with older base station firmware, to remain
compatible. The PMU versions are summarized in the table below:
