3.2.4.1 RX FILTER
The RX FILTER is used for receiving and repeating the received Rx signals. The Rx sig-
nals are distributed by the RX FILTER and passed on to the respective Channel Units
(CHU).
The number of RX FILTER depends on the number of receiving antennas (Rx antennas).
One RX FILTER is required for each Rx antenna.
The following figure shows the front view of the RX FILTER. The following table describes
it in detail.
