Antennas are transducers that transfer electromagnetic energy between a transmission line and free space. Antennas are in general reciprocal devices, which can be used both as transmitting and as receiving elements. This is how the antennas on cellul

Linearization techniques are incorporated into power amplifiers and transmitters for the dual purposes of improving linearity and for allowing operation with less back-off and therefore higher efficiency. This article provides a summary of the three
