This section describes the RF amplifier module. The RF amplifier module contains the intelligent forward amplifier module
(IFAM) and intelligent reverse amplifier module (IRAM).
The IFAM provides all forward signal amplification outside the iRPD in the node. It contains four forward amplification paths.
The forward amplification paths have one common input, and each of the forward paths functions the same.
The IRAM provides all reverse signal amplification outside the iRPD in the node. It has four independent signal inputs (from
ports 1, 2, 4, and 5). The reverse signals from ports 1 and 2 (left side) are combined as well as the reverse signals from
ports 4 and 5 (right side). These (left and right side) reverse path signals then travel through the on board reverse configuration
circuitry. This reverse configuration circuitry determines whether the (left and right side) signal paths remain segmented
or if they are combined.
There are no physical test points on RF amplifier module, forward and reverse path. Built-in spectrum capture circuitry is
used to monitor the forward and reverse paths.
To save power, the user can independently turn off any of the forward path gain blocks. The node can also automatically adjust
power consumption based on the channel plan. Note that this feature is disabled by default and the user needs to use LCS to
