If someone can give me a reasonable guess as to the equivalent circuit
of the transformer and the IC (U5), I can do the rest of the job
myself using the aade filter software.

Thanks,

You might try FilDes:
ftp://ftp.lehigh.edu/pub/listserv/qr...ols/fds201.zip

It will let you specify different source and load impedances for the
filter being designed, so you can probably get away without the
transformer altogether. The AADE software has a nicer interface but
I've always liked the functionality in FilDes better.
