    BANDSTOP FILTER

    Deti offer both connectorized and Waveguide notch filters. Waveguide bandstop filter are used when a high power handling and very low insertion losses are needed.

    Connectorized filters are divided into two categories plannar (PCB) and mecanical. Mecanical Filters offers high end performances with low insertion losses and sharp rejections. However, being more affordable PCB filter can be a good alternative depending on your needs.

    Make sure to Contact us if you have any question or if you need a new design/a customization on one of our existing products as we do offer custom designs.

      Bandstop Filter – 1090 MHz

      BSF-IN-1089-1091-80-NM-NF
      This Mecanical Interdigited Band Stop Filter allows you to sharply reject (80 dB) the 1089 - 1091 MHz frequency range while avoiding to degrade your signal from 1020 to 1040 MHz. Indeed it show very little insertion losses (0.5 dB) and a vswr of 1.20:1 max. It is design to cope with very high input power as high as 200W average and 4000 W peak.

    A bandstop filter is design reject signals on a given bandwidth, called “stop band” and will let pass signals outside this stop band. Also known as notch filters, they are usually done by coupling quarter length resonators. The key parameters to look at when choosing/designing such a device are as follow:

    • Fmin and Fmax Rejected: the frequencies defining the bandwidth of the stop band. A level of rejection is also defined within this range.

    • Pass Band Fmin and Fmax (01/02): it defines the pass band both before and after the rejected bandwidth. Insertion losses and return losses are usually given within these frequency ranges.

    All of our bandstop filters are designed to be compact and to withstand severe environmental conditions making them usable in all your projects.
