FM Bandpass Filters
2P, 3P Series

RFS bandpass filters are primarily used as part of multi-channel combiner facilities but can also be used to eliminate spurious emissions and increase isolation between co-sited services.
The filters are designed with all bolted connections and any sliding contacts are at low current density points to ensure maximum reliability and ideal power ratings for a given physical size.
Each filter comprises several 2 or 3 coaxial resonators which are aperture coupled. The fixed aperture coupling design is engineered for a constant passband wherever the pass band is tuned in the 87.5 - 108MHz band. This design ensures standard insertion loss and rejection for each filter model, although custom filter performance (modified aperture coupling) is available on request.
