Radial stubs in the Rf design

Hi,

do a search on this forum. Radia stubs have been discussed in several threads.


Rgds

you can see my topic for help of this

Is any radial stub equivalent to a capacitor?

A radial stub, looking like a 1/4 piece of pie, is actually an open circuited transmission like stub. If you are trying to build a bias tee (using a high impedance line, followed by a radial stub) operating from 2 to 4 GHz, for instance, the radial stub electrical length should be approximately 90 degrees long at 3 Ghz, so it acts like a short circuit over most of that band.

Hi,

these are the pages from

Brian C. Wadell:Transmission Line Design Handbook

you can find design information about radial and delta stub there.
