PolyPhaser RRF-220-NFF

Positive Train Control (PTC) Filter

Positive Train Control (PTC) Filter, Railroad RF Band Pass with Surge Protector, 217 MHz to 223 MHz, Type N F/F, 100W CW, IP67, 50uJ, 10kA. Positive train control (PTC) filter with surge protector RRF-220-NFF from PolyPhaser is in-stock and available for same-day shipping. This railroad band pass filter is part of the RRF series that is engineered specifically to minimize RF interference for rail operations. These filters are used in positive train control networks and reduce the interference from internal and external sources. PolyPhaser railroad band pass filters increase the effectiveness and reliability in communications within those PTC systems. PolyPhaser RF positive railroad train control filter component part number RRF-220-NFF is a band pass filter with a passband frequency range of 217 MHz to 223 MHz. This PTC filter with surge protector is designed to block interfering signals from co-located radios at different frequencies and provide pass band frequencies between 217MHz and 223MHz. This PolyPhaser railroad train control RF bandpass interference filter with surge protector incorporates Type N connections. These Type N to Type N filters for railway radio interference have a female N Type input and a female N Type output. PolyPhaser’s 217 MHz – 223 MHz band pass filter is rated at a maximum power of 100 Watts CW. The 100W CW interoperable train control / advanced civil speed enforcement system interference filter for 217MHz to 223MHz passband from PolyPhaser is IP67 rated. These PolyPhaser IP67 railroad radio frequency filters with surge protector for PTC are independently tested to meet key industry standards for shock, vibration, temperature and filtering. As leaders in RF surge suppressor technology and experts in positive train control, Polyphaser has designed these state-of-the-art bandpass solutions for the demanding needs of the railway market. This N Type band pass filter for railroad train RF applications is in-stock. Not only is part number RRF-220-NFF in stock, but like the other PolyPhaser components, this positive train control filter with surge protector will ship the same-day.
