PolyPhaser expands High Performance Band Pass Filter Series
January 16, 2013
Locomotive-specific models of band pass filter series is now available from PolyPhaser
After the recent introduction of a new rail band pass filter series for wayside bungalows, PolyPhaser Inc., a Smiths Interconnect business, today announces the release of three additional models specifically designed for locomotives.
PolyPhaser RRF Band Pass Filters effectively minimize noise problems by blocking unwanted signal interferences. Such noise problems are caused by a multitude of direct and indirect sources, such as passive intermodulation, cell tower, radar or power line interferences. Reliable data transfer with minimal signal interference issues, however, is critical to the successful implementation of Positive Train Control, a complex system of advanced technologies to enhance safety and uninterrupted traffic flow.
With more than -20dB return loss, less than 0.9dB (1.5dB for 450MHz model) insertion loss and more than -60bB out of band rejection, PolyPhaser Band Pass Filters provide the industry’s leading signal integrity protection. In addition to the 160 and 220 MHz wayside models, Locomotive RRF Band Pass Filters are available for 160, 220 and 450 MHz frequencies.
All series models feature integrated high performance surge protection and frequency-coordinated colored labels to effectively reduce installation and maintenance complexities.
