Hello,
i am designing a wideband LNA right now and would like to replace the Piconics conical inductors we are using right now with a planar Bias-Tee.
My bandwidth is from 1-9 GHz so i cannot realize it with a quarter wavelength line and a radial stub. Is there a way to use a form of cascaded design with radial stubs or some kind of broadband transformer?
Please give me some tips on further research if you like!
Sincerely
Chris
