220MHz Band Pass Filter for Railway applications PolyPhaser’s RRF-220-NFF rail band pass filter is designed for 220 MHz wayside rail applications. The band pass filter series RRF-160-NFF and RRF-220-NFF are specifically designed for railroad PTC (Positive Train Control) systems and engineered to reduce inte more...
The TC Series Filters yield a butterworth (maximally flat) response and are available with 2 thru 8 cavities. Tuning is accomplished by means of a single knob which is coupled to a precision gear train. All conducting surfaces are silver plated to minimize insertion loss in the passband. Filters in this serie more...
API Technologies’ reputation for designing and delivering some of today’s most challenging Bandpass filters is the reason why engineers trust us with their designs. Choosing from a wide assortment of topologies, including lumped element, cavity, ceramic, SAW, tubular, suspended substrate, and waveguide; o more...
Anatech Electronics cavity band pass filters are available in a wide range of frequencies, power levels, bandwidths, and rejection. The resonators and cavities are silver plated for low RF resistivity, in order to achieve low insertion loss and high selectivity. The RF band pass filter size depends on perfor more...
