Interference filters are frequently employed in transmissive configurations where the light passes through the filter to produce a specific effect (band-pass, long-pass, short-pass, among others).

J-Shield is a robust filter on Javad GNSS antennas that blocks out-of-band interference (Figure 1). In particular, J-Shield blocks signals that are near the GNSS bands, including the proposed Ligado ...

Last month, we discussed various types of RF-resonant cavities. This month the discussion focuses on the actual use of these cavities to mitigate RF interference. Due to RF congestion at popular ...

Researchers from Siberian Federal University and Kirensky Institute of Physics have proposed a new design for a multimode stripline resonator. The use of such resonators allows scientists to create ...

RF interference caused by PTC radios operating at different modulations has been a problem that railroads have acknowledged and worked to overcome since the start of PTC planning and installations.

Dawnco is emphasizing the post-9/11 importance of C band satellite terrestrial interference filters. The filters are placed between the feedhorn and LNB of a C band downlink. TI filters clean up ...

HACKETTSTOWN, N.J. – AstrodyneTDI in Hackettstown, N.J., is introducing the F series facility and shielded room power line filters to enhance safety and block unwanted electromagnetic interference in ...

Board mount EMI and RFI filters are electronic filters which mount on a printed circuit board (PCB). They attenuate radio frequency interference (RFI) or electromagnetic interference (EMI).

Widespread availability of Wi-Fi functionality on smart devices, the potential for an overall improved quality of service (QoS), and the ability to stream video to smartphones in dense environments ...

Optical filters are devices, typically comprised of plate glass or plastic, which selectively transmit light of different wavelengths. Filters can be broadly classified as absorptive or dichroic, ...
