Hi,
sometimes whilst using Autocad LT2002 I have noticed that the ZOOM function attributed to the center wheel on my mouse stops working. It starts schrolling instead. This change in function then stays with ther drawing file.
Why is this, and does anyone know a way of changing this back to...
It depends on the frequency.
At higher frequencies where the wavelength is suitably small the 90 degrees shift can be achieved by a length of transmission line.
At lower frequencies where the parasitics of components do not have such an effect you can acieve a 90 degree difference in the two...
Does anybody know of a good reference text for co-axial waveguide?
I want to design a dual band feed for a front fed parabolic dish. One band is twice the frequency of the other. The lower band will be fed via co-axial waveguide excited in the TE11 mode. The higher frequency will be fed through...
