DESCRIPTION:Abstract\nDoherty power amplifiers are widely used to achieve h
 igh efficiency with high-PAPR signals\, but their extension to millimetre-
 wave frequencies is far from trivial. At high frequency\, classical Dohert
 y assumptions no longer hold\, and efficiency\, gain\, bandwidth\, lineari
 ty\, and implementation constraints become strongly interdependent.\nThis 
 lecture provides a design-oriented perspective on the key challenges limit
 ing high-frequency Doherty operation and discusses practical methodologies
  to address them. Topics include gain behaviour\, on-chip power combinatio
 n\, bandwidth limitations\, and linearity degradation\, with emphasis on a
 rchitectural trade-offs rather than idealized solutions. The discussion is
  supported by measured GaN MMIC examples for 5G and satellite applications
