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 ...

The powerful capability of reconfigurable intelligent surfaces (RISs) in tailoring electromagnetic waves and fields has put them under the spotlight in wireless communications. However, the current ...

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

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 ...

Surface acoustic wave (SAW) filters may sound exotic, but they are everyday workhorses in wireless front-ends. Compact, cost-effective, and reliable, they shape signals with precision while keeping ...
