RF Filter Design

Design RF filters such as Butterworth, Chebyshev, Inverse Chebyshev

Use the RF Toolbox™ rffilter object to design Butterworth, Chebyshev or Inverse Chebyshev filters with highpass, lowpass, bandpass, and bandstop responses.

You can also use the rffilter object or RFCKT filters to design filters with different implementation types.

Data Analysis on S-parameters of RF Data Files

Perform statistical analysis on a set of S-parameter data files using magnitude, mean, and standard deviation (STD). First, read twelve S-parameter files representing twelve similar RF filters into the MATLAB® workspace and plot them. Next, plot and analyze the passband response of these filters to ensure they meet statistical norms.
