5 RAU5X/RXU2325 CAVITY FILTER INSTALLATION
The external cavity filters are required when the RF services modules supporting the corresponding CELL and LTE bands are
deployed alongside units supporting the public safety service.
• The RAU5x supports connections to external CELL and LTE Filters
• The RxU2325 supports connections to an external LTE Filter.
• In cases where an LTE External Filter is required and the RAU5x includes the RxU2325 module – both modules must be
connected to an external LTE filter.
Note the following:
• The cavity filter mounting bracket supports wall/ceiling/acoustic ceiling installations. See Figure 5-1.
Figure 5-1.Cavity Filter Dimensions and Mounting Holes
• Consider the length of the RF jumpers (3 m) and the distance from the RAU5x when determining the installation location.
• For acoustic ceiling installations – use provided safety cable to secure the filter assembly to a permanent structure within
the ceiling (e.g., acoustic ceiling grid or concrete ceiling above).
