In the 6th-order system, like this?

  NST+ o-----+--C1--+---C2---+---L3---(===) term, capacitance C3

A different version of the bandpass magnifier. Probably uses less
wire that the version with two L2 in series, as 2L2 with a central
tap uses less wire than two L2 inductors. This structure can be
designed as the full high-pass version, without shunt capacitors,
with C3 and L3 interchanged. It is faster than the version with a
capacitive transformer at the output. Looks as a good structure.
A real construction would have some parasitic capacitance in parallel
with L2, and it should be included in the design, but if C2 is big
enough (easy) this will make little difference.
You can use the mreshp program to design it, in :

The program now plots waveforms too.
