Hi,
I was going to start an our system and I realized I need a Bias Tee more
and I prefer to not wait for the 4-7 weeks for the delivery!!!! that a
reseller proposed.
So I think Bias Tees are difficult to build only for broad band application.
unfortunately are some years I don't study/make electronics and I don't have
here books... so I'd be glad if someone could give me the formulas to let me
configure a Bias Tee.
DC ---@--+
AC ------||--+-------- AC+DC
GND -------------------
DC-AC-GND are clear... @ is an inductance L and || a capacitor C.
At the moment I use a RF signal between 1 and 100MHz, a DC of 0-10V on a
350mA. I need the Bias Tee to mix and unmix the DC-AC so I don't just need a
DC block.
If you can give me the formula or some direct reference to some web or book
resources I'd be very glad so I could dimension my BiasTee also if I decide
to work in another frequency region.
Last things.... which parameters let me to distort less then I can my AC
signal (usually it is a sinewave but sometimes also a square one).
Thanks!!!!!!
