Hi friends,
I am Nicholas from University Technology Malaysia. I am doing my final year project on a 2-way miniaturized wilkinson power divider.I have a few confusion and need help. I manage to get results as below:
S11=-32dB
S22=-26dB
S33=-26dB
S12,S21,S13,S31=-3.01dB
S23,S32=-30dB
Are we suppose to get the same s-parameter values for S11,S22 and S33?If the valueare not same as above,whatwill be the problem?
By inserting groove to the layout design, i manage toget almost same value for the returnloss.Is it better?because i have seen designs with almost same value and designs with different values.
Another question is, assuming 10% power loss at each output arm,is itstill acceptable in the industry for 40%:40% equal power split?
Thank for the help!
