RF filer design Matlab
2 views (last 30 days)
I am new to Matlab and RF Toolbox. I designed a Butterworth bandpass filter. Everything seemed to go OK, except I cannot see what the L & C values for the designed filter are. I can see S params and plots, but for this to really be a filter design tool, I need it to output the actual component values. ???

I don’t have the RF Toolbox (since I don’t need it, although earlier as a U.S. Amateur Extra Class Amateur Radio operator, it would likely have been useful) however your question interested me enough to go searching.
The example in the rffilter documentation gives the component values, however you have to ask for them —
Using an example from the documentation —
robj = rffilter('ResponseType','Bandpass','Implementation','LC Tee','PassbandFrequency',[950e6 2200e6], ...
robj.Name = 'BFCG_162W'
The lcladder function produces them. There might also be other appropriate functions. See the Functions link for a list of all of them.
