Starting from the antenna and finishing at the modem, the front-end module is one of the most important parts of an RF system. Based on the application, RF front-end (RFFE) modules are available in ...

One of the most complex parts of enabling 5G is mmWave frequencies and the antennas and front-ends that control them. MmWave technologies have never been used for mobile cellular communications before ...

With the exception of the iPhone, Apple's products largely lack technology to provide ubiquitous access to the outside world while on the go. However, a new proposal from the company would attempt to ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

A single-photon detector (SPD) is sensitive to incidence of individual quanta of light and has many applications in photonics, such as fluorescence measurements, laser ranging, optical time-domain ...
