Nonlinear and memory effects in RF power amplifiers significantly impact signals in modern communication systems.

To judge the expected nonlinearity of an Amplifier during the design process two-tone simulations are used, as they have similar characteristics to modern modulations schemes. For more advanced amplifier configurations it is unclear how two-tones simulations relate to real signals. To study this behavioral models of the amplifier can be used to reduce computing demand.

The student will use a behavioral amplifier component  provided in ADS to model a transistor core. Then modulation schemes will be applied to the model and the response studied.

Tasks:

-Understand the ADS provided model

-Extract needed parameters from provided core and compare model to layout

-Model different modulations and compare behavior to two tone simulations

Requirements:

-Good understanding of circuits

-Interest in modeling and Power Amplifiers
