Hi to all

is it possible to use the same transformer
in the range of KHZ on the one hand
and on the other the same one for
MHZ?

thanks a lot

Depending on the impedances and power levels, you should be able to get a broadband transformer to work over about 3 decades (like 100kHz to 10MHz, or 1MHz to 100MHz), or maybe more with specialized construction techniques.

Here's the hit list from googling broadband transformer pulse transformer, including some nice design application notes:

What actual frequency range are you interested in?

thanks

it is intersting
is there really option to work in decades like you mention
100k then 10 mhz

can it be a coils for PCB technology

i couldn't find some

thanks
