power divider with harmonic supression

[Nicholas_UTM]

I manage to design a 2-way wilkinson power divider with the 3rd harmonic supression.below are the results..
f0=3GHz
3f0=9GHz
AT 3GHz
S11=-30dB
S22 & S33=-28dB
S12,S21,S13,S31=-3.01dB
S23&S32=-26dB

AT 9Hz
S11=-.07dB
S22 & S33=-dB
S12,S21,S13,S31=-24dB
S23&S32=-6dB

Are the results good enough. The design of the power divider was carried out by modifiying the transmission line into coupled lines.
by the way,can someone give me the URL to get buy chip resistor online..
thk for the help[/b]

No your results stink. Simulate with real losses and post again!

AT 3GHz
S11=-30dB ----------->Good input match
S22 & S33=-28dB--------->Good output match
S12,S21,S13,S31=-3.01dB--------->(Good) almost lossless, air substrate??
S23&S32=-26dB--------->Good isolation

AT 9Hz
S11=-.07dB---------->High Reflection
S22 & S33=-dB------>???????
S12,S21,S13,S31=-24dB--------->Not bad
S23&S32=-6dB------------->lossless??
