Dear Lars,
The problem is in the network LBC2R_Obj: it is built as a series, while I think that you wanted to have a cascade (correct me if I am wrong). Please the difference between rfckt.series and rfckt.cascade. If you change the construction of the network as follows: LBC2R_Obj =rfckt.cascade('ckts',{LB_Obj,C2R_Obj}); then the analysis of MatchedFET is correct.
A small tip: you can use rftool to visually inspect and analyze the objects you build in the MATLAB workspace. I find it quite useful to debug objects.
I hope that this helps, with best regards, Giorgia
