I am not a RF designer, mostly work with power and digital design. Was curious to make a 3rd order Chebyshev Bandpass (type1) with the help of some software from the web.
I want to use it in the TV VHF band to pass one channel and stop others.
The design parameters are:
Center Frequency: 204 MHz
Pass Band : 6M Hz
Impedance : 75 Ohm
I was using AADE Filter Design And Analysis Ver. 4.5, That gives the following component values and response.
And Filter Free Ver. 13.5 from Filter-solutions.com That gives the following component values and response.
The above two software gave very different L/C values and some values are too small for practical use.
Is there any simpler practical way to find the optimum values for practical use?
