Analyze RF JFETs for Large-Signal Behavior (.PDF Download)

Jan. 23, 2017

Linear amplification is a requirement for processing many waveforms, although achieving high amplifier efficiency with linear performance might present a challenge. For example, terminating a JFET in an optimum resistance (Ropt) at one-half the maximum current, or Vdc/(Imax/2), does not result in linear amplification with 50% efficiency.1 For that reason, it is necessary to reconsider the way that FETs are analyzed. Linear models cannot be used—one must first solve the equations that describe a JFET’s behavior to better understand and improve the performance...
