Performance analysis of 9th order Chebyshev filter at microwave frequencies

Abstract

In this paper the performance analysis of ninth order microwave filters (Lowpass filter, Highpass filter, Bandpass filter) has been done. The analysis is done on a general frequency range that falls under microwave frequency range for all the three filters. The filters are used for different applications in their range. This paper covers the design analysis of the three filters on Electromagnetic (EM) Circuit Simulator respectively along with their performance analysis curves and further this practical analysis of the filters is compared to their corresponding theoretical response as obtained from MATLAB by using the transfer function for the filters respectively. MATLAB coding has been done for plotting the expected response of the filters and calculation of lumped elements values i.e inductors and capacitors for a general frequency range which makes the practical design of the filter easy.
