F/A Band Uplink Interference Suppression Filter
In the case of site sharing of multi-operator and multi-standard networks, if the network isolation is not good enough, it may cause serious barrage jamming problem. And it is difficult to solve the problem in a timely manner due to the long process of project rectification approval and the limited space of the site platform. In this case, installing an interference suppression filter is the best solution to eliminate barrage jamming.
The filter is characterized by:
1.High protection level (IP67)
2.Small body size (248mm*253mm*97.5mm)
3.Support F and A band pass filtering at the same time
