Researchers have developed a new chip-sized microwave photonic filter to separate communication signals from noise and suppress unwanted interference across the full radio frequency spectrum. The ...

Are we technologically ready for 6G communication? A recent study published in Photonics Research might answer that question as a team of researchers have developed a novel chip-sized microwave ...

Digital filters lie at the heart of modern wireless communication, shaping signal spectra for transmitters and receivers to meet stringent performance, spectral and ...

German spin-off produces terahertz filters thinner than a virus for space and medical use ...

Filtering plays an essential part in nearly all communications systems. Removing unwanted signals is part of system design to eliminate unwanted noise or distortion. The signal presented to the analog ...

A digital replacement for analog intermediate frequency (IF) filtering, such as that applied in spectrum analyzers, can now be obtained as a block of intellectual property (IP). And, that IP can be ...
