Design a low-pass, third-order maximally flat filter using only series stubs. The cutoff frequency is 4 \( \mathrm{GHz} \) and the connecting line impedance is \( 75 \mathrm{Ohms} \). Sketch the resulting circuit with the characteristic impedance and length of each line. You may leave the line lengths in terms of wavelengths on the line. Hint: Use Figure 8.25a for your low-pass prototype.
