NexTek offers a range of Band Pass Filters, for Positive Train Control networks as well as any other systems that have to deal with Co-Located RF Transmitters and Receivers. In any RF Transmission heavy area (Train Networks, Cell Sites, etc.) where multiple systems are operating near to one another, there is the risk of these systems interfering with nearby systems, whether that interference takes the form of lowered performance, system unreliability, or actual system damage.
These Band Pass Filters provide high-performance notch filtering for maximum control in order to prevent unwanted interference with other Radio Systems. With a sharp insertion loss cut-off immediately below and above the rated Pass Band, unwanted energy is not allowed to pass the filter itself and cause any damage or unwanted system interference.
