High-power gaas fet amplifiers
WebAbstract: The application of stacked-FETs in power amplifiers allows for a supply voltage higher than supported by the breakdown voltage of a single transistor. Potential benefits … WebAt X-band, power FETs often have 150 um wide gates. At Ka-band the the gate width is typically 75 micron maximum. At W-band perhaps 40 micron fingers is the upper limit. Gate width versus gate length A gate finger refers to a single gate structure. Gate periphery is the total size of a FET.
