This year also marked the return of CVD diamond devices, this time using hot-filament CVD, offering much higher frequencies with higher Q&#8217;s than polysilicon and proving that this method of deposition is every bit as effective as the microwave CVD used previously. Finally, the first MEMS-based Class E power amplifier using a micromechanical resoswitch to achieve power gain came this year.<\/p>\n\n\n\n<p>W.-C. Li, Y. Jiang, R. A. Schneider, H. G. Barrow, L.
