Re: NEC-LIST: Designing a power splitter with a 90-degree phase

Azmat,

What is the bandwidth you need, the input impedance, and the two output
impedances?

Subject: NEC-LIST: Designing a power splitter with a 90-degree phase

I'm trying to design an antenna up to 250 MHz and I would like to design
a
power splitter. One of those "splits" should cause a 90-degree phase
shift. I have thought of using the "TL" line with one end having a
purely
imaginary impedance and the other end as well as the character all real
(50
ohms for real and j50 for imaginary).

Seems like the solution is too simple. Is there a better (and correct)
method to implement such a split? Thanks for the input.
