Advanced Modelling Techniques Enabling E-Band Power Amplifier Design for 5G Backhauling

In this paper, a nonlinear transistor model extraction technique oriented to E-band power amplifier design is discussed. Two models are extracted, based on analytical functions and look-up-tables, respectively. The latter was used for the design of two power amplifiers (PAs) covering the bandwidths 71-76 and 81-86 GHz. The models have been fully validated by comparing their predictions with measurements carried out on the realized MMIC PAs.
