Recent advances in high-speed data converters now digitize or generate signals directly at radio frequencies up to several gigahertz, replacing traditional radio-frequency (RF) components like mixers, ...

For the most part, the mechanisms of the natural world around us, including sound, operate in the analog domain. And so the transducers used to convert sound into electrical signals (microphones) and ...

RF receivers are electronic devices that separate radio signals from one another and convert specific signals into audio, video, or data formats. RF receivers use an antenna to receive transmitted ...

Testing transceiver and converter interfaces requires orthogonal in-phase and quadrature (IQ) analog signals; that is, the phase relationship of the two must be very close to a 90-degree phase offset, ...

Beamforming is used for directional signal transmission and reception with the versatility to change both amplitude and phase to help regulate power needs and steer the beam in the intended direction.
