But 2nd order Chebyshev is LC filter, isn't it? How should be represented by R and C only? Why four values?
Yes it is LC filter. I am sorry for the mistake above.
The values of my Chebyshev filter are:
Center Frequency : 2205 MHz
Bandwidth : 60 MHz
Passband Ripple : 1.3 dB
System Impedance : 50 Ohm
Order of Filter : 2
--------------------------------------------
Element 1 , Orientation : series
C = 0.019 pF, L = 269.881 nH
Element 2 , Orientation : shunt
C = 35.16 pF, L = 0.148 nH
---------------------------------------------
These are the values I got from an online calculator.
I need to calculate the transient response and transfer function now. Can you please help me find a calculator for that?
