Module Function
Reverse
Conditioning
module
Allows for selectable tap loss in the reverse path using discrete
attenuator pads.
Gainblock
Adds gain in both the forward and reverse paths. This is necessary
to allow the AMST to "drop-in" to existing plant designs.
Power supply
Converts the AC voltage on the input to a well-regulated DC
voltage for station powering.
Internal splitter or
switch
Takes the RF input and runs it through splitter circuits to evenly
divide the RF signal between all the tap output ports. The signal
then passes to an RF switch, which is controlled by the
microcontroller.
The RF switch either passes the RF through (short) or terminates
the signal with a 75 Ω resistor.
