If you mean the quadrature hybrid, I use an FT37-61 toroid core. One of
the smaller Mix 61 balun cores should also work, but with the toroid you
can trim the inductance by spreading or compacting the windings on the
If you mean the transformers for the push-push FET doubler, I usually
use commercial parts (MCL or Coilcraft).
