The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in ...

Peregrine Semiconductor’s DuNE technology solves one of the orneriest problems in RF design—antenna impedance matching. In every wireless application, an antenna has to be connected to the radio. That ...

This file type includes high resolution graphics and schematics. Cavendish Kinetics now offers a tunable RF micro-electromechanical systems (MEMS) capacitor that lets smart-phone antennas cover a ...
