Question 4 You will design a Chebyshev filter for a Ku band satellite receiver operating over the bandwidth of 12.5-12.75 GHz. The filter should reject an interference signal at 13 GHz

by 50 dB. The permitted in-band ripple is 0.5 dB (Note that in practice this is typically 0.04 dB or even lower). The source and load impedances are 50 Ohm. You should use minimum number of orders (or sections) for the filter. The Chebyshev filter required is a passband filter Your submission should include: • A detailed workout of the design including any calculations. You can use Excel spread sheet or MATLAB if you want, but no other software is allowed. In all cases, calculations should be fully explained in the word document. [20 marks] • A figure of the filter response of your design, plotted using the MATLAB routine provided in the lecture. Set the frequency range from 12 GHz to 13 GHz at a step of 5 MHz. Marks will be awarded to the design process, not just to the correct final answers. [5 marks]
