MC-TECH 's MBF band pass filter is primarily used for narrow band applications. Pass bands are typically from 1% to 4%. This design is well suited for frequency diplexers used in communication systems or any applications where narrow bandwidths are required. Insertion losses are typically in the 0.8 dB to 2.0 dB area depending upon rejection levels. The CBF series band pass filter can be designed from 3 to 170 GHz up to 30% bandwidths in 16 waveguide Bands. Please consult Cernex for further dimensions and specific technical data.
