Cutoff Frequency Analysis

    1. Design a five section low-pass equal ripple filter with a 3dB equal-ripple response, a cutoff frequency of 2 GHz and a source impedance of 50 Ohms. Use ADS to plot the insertion loss with frequency. 2. Design a five section high-pass lumped element filter with a 3dB equal-ripple response, a cut-off frequency of 2 GHz and a source impedance of 50 Ohms. Use ADS to plot the insertion loss with frequency. 3. Design a three section bandstop lumped-element filter with a 0.5 dB equal-ripple response, a bandwidth of 10% centered at 3 GHz and an impedance of 75 Ohms. Use ADS to plot the insertion loss with frequency.
