hello!
i'm trying to design a nutler matrix at 10GHz using this architecture **broken link removed**
i've designed the 3dB coupler and the crossover, here are the results of the simulations:
for the coupler: (port 4 is the isolated port)
**broken link removed**
for the crossover:
my problem is when i gather the components i get weird results and i don't understand why. here is the layout:
normally i'm supposed to have -3dB at port 2 and 3 and a good isolation on the ports 5 and 4, instead i get this :
thank you in andvance.
