The gain of the Bias-Ts is defined according to the system design.
The Active Bias-T comprised of a boost amplifier and a digital controlled attenuator in order to adjust
the gain and enable a convenient interface to the Control features. The gain of the ABT assemblies is
Temperature Compensated.
The Rx ABTs are transparent to the FSK communication channel which enables the M&C
communication with the BEAMER
®
units in the FLEXBEAMER® and the BAU.
In this manual, Bias-Ts are also termed 'sub-array', since each Bias-T can serves an independent portion
of an array (i.e., Tx sub-array or Rx1 and Rx2 sub-arrays, which are all physically part of the same
array, but are logically independent entities).
