Power Amplifier Modeling and Pre-distortion Synthesis Using MATLAB
Budget: $30 – $250 USD
o Using the provided data, draw the AM/AM, the AM/PM and the output power vs. input power characteristics of the device under test.
o Build a look-up table based model of the device under test (AM/AM and AM/PM) behavior.
o Apply the input signal to the designed model, and compare (in time and frequency domains) the model output to the measured output. Quantify the error between these two signals. What can be the origins?
o Using the device under test model, synthesize a suitable digital pre-distortion lookup table.
