Even though they are an older technology, Gunn oscillators have been playing a unique role in replacing the tube to generate low to medium level microwave power within the 2 to 140 GHz frequency range. New generation engineers may have some opportunities to use this technology due to the birth of three-terminal based devices such as HBT, MOSFET, and pHEMT. This article reintroduces the Gunn oscillator technology and discusses how it pertains to those who need to use it today. Download the full article for more information.
