As long as you take account of the value of ε implied by your selection of 0.1 dB ripple in the passbandI did a quick hand calculation with the Butterworth transfer function to determine the filter order so I assume that it is basically the same but with the Chebyshev transfer function, is that correct?
Please forgive me I feel like such an idiot.And just how does that work at 10MHz???
'saright -- small details are really surprisingly easy to overlook, especially at the concept stage before any actual hardware is built.Please forgive me I feel like such an idiot.
* I cannot understand why the last 4-stage filter in your original post contains one 2nd-order stage (the 1st one) which uses a passive RLC lowpass. Why not a S&K stage like the other three?I do not know about the "direct" realization and will try to find out more about it but if you have literature suggestions I will be very happy to read up on them.

The circuit is the last one in my original post, there is no option to choose passive realization.
