Translated title:
Design and implementation of bandpass filter with the Pascal approximation in microwave frequencies
Summary:
The presented master thesis has the target to design and implementation of bandpass filter on microwaves frequencies using the Pascal Approximation. Initially i introduce the reader to the basics of analog filter design.
The second chapter describes the most known all-pole approximations(Butterworth and Chebyshev), after the brief introduction to the all-pole approximations, I describe the Pascal approximation. In the end of the second chapter is mentioned the calculation of the coefficients of the Pascal function.
In the third chapter is designed and implemented in the simulator Multisim a bandpass filter with the use of Op-Amps(freq. range 10Hz-10MHz) and I mentioned the transformation of LP to HP filter and LPF to BPF.
In the fourth chapter we repeat the same procedure of the third chapter, with only difference not using Op-Amps but only discrete elements(freq. range 0.5kHz – 1GHz). In the end of the current chapter there are tables with different ripples with the values of normalized discrete elements of LP filter, the same tables are on the book of A. Zverev but with different Approximations.
Last but not least chapter after a brief introduction to the Microstrips, is designed a LP filter with the method of stepped-impedance, after I design a Pseudo High Pass with short circuited stubs with FBW 0.85.Both filters are designed and simulated on the program CST and both on the freq. range 1GHz to 10GHz.
