reflection type dro

hi all,
i am new in this forum and this is my first post
i am designing a DRO at the moment ,the problem is that i have very few resources thus i am wondering if any one can help me with any.
thanks in advance

well i have found some interesting application notes on the cel.com sight ,
search for an1035 it's all dro...
besides a less discriptive application note by siemens on siemens.com
you will need to simulate the dielectric cavity on a 3d EM simulator to be able to get the coupling coefficient (β) and the distance from the in feed as far as i remember ..
if u get any thing just strew it over ...
you will find a paper attached here it might be of some use don't forget the subharminc oscillations test it might alter the whole system performence

pl indicate exactly what kinda help u require... i mean papers, notes, books, references, tools.. what exactly is the problem that u r facing...
regards.

hello,
my problem is that i can't really run the harmonic balance simulation properley , i did everything that's s in the text book and when i put the oscillator test port in the simulation it gives me strange error messages like(the point 1+j*0 is encircled in a ccw direction hence nyquist criteria is not satisfied) and i really don't know hoe to choose the proper value for the oscport of the harmonic balance so what should be done? i am using @ds by the way...
thanks in advance
