Abstract: Future efficient wireless communication systems require, for high quality performance a Broadband Amplifier in the frequency range under consideration. This could be plugged into the measuring path so that it enables the system to perceive even the weakest signals. For this a new Scattering-parameter model for the microwave analysis of a PHEMT has been developed, which is valid for a wide frequency range. The developed neural network model is used in designing the PHEMT power amplifier. The calculated S-parameters, gain and minimum noise figure from the ANN model are the parameters which are used to design the low noise PHEMT power amplifier. The various gains so obtained from the S-parameters are plotted with the frequency and yield a closer fit to the simulated model. The neural network training has been done using Levenberg-Marqaurdt back propagation algorithm implemented in ANN toolbox of MATLAB software. All the results have been compared with the experimental!
data and show a close agreement and the validity of our model.
