[/list]Hi Steve  I have a new design with the lowest HART loss  But it appears the Achilles  heel in the design is that the 2 x 1mH inductors rated at 2.4A are only 1 MHz SFR!!!  To solve this maybe you need have 3 inductors in series with no overlapping SFRs or find some amazing wideband ham RF choke.  1 mH  (~1 MHz SFR in series with 0.1mH (~10 MHZ SFR) in series with 0.01 mH ( ~40-100 MHz SFR  maybe Digikey 732-3412-ND ) Xxxx ???  RegardsLen
