RF (Radio Frequency) GaN transistors may be used for power switching at frequencies of 30 MHz and above. thereby reaching voltage control bandwidth of critical interest for the so-called ET (Envelope Tracking) technique. ET is meant at optimising the efficiency of RF amplifiers by supplying them with a voltage adapted to their power level at any time. and is the subject of many R&D wo... https://www.spidertattooz.com/Powell-Mahoney-Bloody-Mary-Mix-750ml/
