We have special variety of notch/bandstop filters which is designed and manufactured specially for ISM band.

These filters are for use in wireless broadband systems operating within the ISM band of (902-928) MHz and (2.4 – 2.483)GHz. These filters remove interference originating from services operating in nearby frequency bands (e.g. paging systems & cellular phone providers). The 902 -928 MHz filter is weatherized notch filter and designed specifically to eliminate interference caused by high-powered paging systems operating at 930 MHz. The 2.4 -2.483 GHz filter is designed to notch out the WLAN 802.11b spectrum. These filters have compact and sturdy designs which operates over a wide temperature range, making it ideal for installation in virtually any indoor or outdoor enclosed environment.

The table below shows various notch/bandstop filter models and its cut off frequencies many of which may be customized according to your specifications.
