i ahve just finished the design of a ku band dro, i used @ds the problem is that when i generate the layout i find that there is a gap to acconut for the placment
of the OSCPORT (like those for the resistors ,caps ....) the question is should i remove the oscport before generating the layout...
i think boy is correct ,according to the transistor type u r using the noise may not by incooperated witn the model u can check that by looking up the noise parameters in the transistor model u r using.
as flatlutenet has mentioned ,with refrence to the NYquist stability criterion shows weather the system is oscillatory or not ,this is basiclly determined by studying the open loop transfer function of the desired system when the O.l TF HAS NO poles in the right hand planes then the...
i have noticed that your questions are basic and conceptual,may i suggest that you reinforce your theoritical background about analog design,microwave enginnering and RF circuits,you can start with G. gonzales 'microwave transistor amplifier design' for RF circuits,David pozar's 'microwave...
you can generally account for parasitics of devices using the component model given by the manefacturer just choose the prorper ideal values of resistances and capacitors then use the exact model(0603 package resistors ,caps) supplied by the manefacturer build it up or use the ready made...
Re: Impedance in ADS
running an s parameters simulTION and plotting s11 on a smith chart will give you the value of the zin associaated with the s11 at the frquency of interest besides you can define an equation that gives you the value of zin
zin=(1+s11)/(1-s11) then include it in a table you...
Re: Floquet analysis
you can find a brief discussion of the theorm in samuel laio's 'microwave devices and circuits' chapter 9 associated with the analysis of the TWT and periodic structures in general ,also you can find a good insight in collin's 'foundations for microwave engineering ' 2nd...
you might want to check the gonzales book chapter 5 it's all about oscillatorvdesigntheG.D. VENDELIN book (design of amplifiers and oscillators by the s parameter method) would give more description and details about design procedures and stability considerations(sub-harminc oscillations..)
your...
dielectric resonator dro application note
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...
