Dielectric_oscillator_10_GHz

[LeThalois]

hello every one.

I find no words to describe my situation.

there is 2 months that I am designing a DRO oscillator in microstrip technology at 10 GHz,

I tried the following figure, but in vain. :'(

Please, help me, soon my academic defense and I have done nothing yet.

if you know a schema, a list of steps, I would be very happy even with a single encouraging word.

thank you with all my heart.

ADS? I feel your pain. I only barely learned it. I suggest, for what it is worth, to break the loop into two parts; the amplification part and the feedback part, then simulate each part and use the gain/loss and phase data from each part to make sure each part works and that, together, the Barkhausen criteria is met at 10 GHz.

Good luck!

i thank you a lot from my heart

what do you think about this methode

1°-calculate K of a tnt of ower choice

2°-we make a feed back circuit that make S11>1 or S22>1 like this

3°-then resonnate the input port like this

and is this available in loop feed back? this is the document that i use https://www.electro-tech-online.com/custompdfs/2012/05/osc_hyp.pdf

thank you a lot
