Critical to the quality of communication between a base-station transmitter and a mobile receiver is the signal's propagation channel. As it is transmitted over the air, the signal is subject to ...

A tailor-made structure may make microwave WiFi signals more transmittable through walls without reflection, according to new research. This works in much the same way as anti-reflective coating on a ...

When choosing an RF instrument, it is easy to get lost in the many specifications that vendors use to characterize an instrument’s performance. Moreover, in a world where wireless technologies are ...

Most of us know that to get the best possible WiFi signal, you want there to be as few walls as possible between you and the Access Point. But that might soon change, as researchers at MIT have found ...

Unlike power switching FETs, RF FETs are designed to work best in the linear region of operation to maximize power gain and minimize distortion, whereas power switching devices are optimized for ...

Wireless communications products that depend on RF principles are everywhere these days, and the growth rate is astonishing. From cell phones and wireless PDAs to Wi-Fi-enabled laptops, Bluetooth ...
