  • Abstract
    Summary form only given, as follows. An accurate packaged model is reported for GaAs HVHBT 120W amplifiers at 2140MHz. The model can precisely simulate small signal S-parameters as well as large signal harmonic load-pull power sweep. Very good agreement between simulation and measurement has been achieved. The model is then applied to simulate a 250W symmetric Doherty amplifier. The results of simulation agrees well with measurement. The difference in efficiency between simulation and measurement is only 1.6%.
