description: A  linealized  RF power amplifier  using Envelope  Elimination and Restoration (EER) and predistortion techniques is shown.  Measurements on a circuit prototype are presented.  The EER system uses a linear regulator to amplify the envelope  and  a  high efficiency  broadband VHF class E  power  amplifier  for the  phase component.  Different  digital  modulations have  been  tested in the circuit prototype. Adjacent Channel Power  Ratio (ACPR) reaches over 46 dBc for monocarrier modulations  and over 34 dBc for multicarrier modulations,  for a 2MHz  bandwidth  on VHF carrier  (from 88 MHz to 114 MHz). The system shown provides double efficiency level than an equivalent  ideal class A amplifier.
