A highly efficient push-pull class D power amplifier (PA) with a high operation voltage is presented. The high voltage is realized by stacking dc biases of two push-pull amplifiers through the virtual ...

Push-pull structure with balun transformer is presented as load modulation technique which improves the overall efficiency of power amplifier. Under the assumption that output impedance of turned-off ...

The WiiM’s touchscreen – like that found on the Ultra DAC – shows cover art and metadata in a choice of layouts. Or we might ...

This document describes the design, simulation, PCB layout, and testing procedures for a two-stage wideband RF gain block amplifier covering 0.1 to 50 MHz. The amplifier delivers 24 dB gain, a nois ...
