Hi,i am a fresh for designing PA . can anybody tell me where i can download some PA Design examples with MWO software step by step.or some links ,some articles,your experience,etc. the original design file is better....i assure u that i only use them for study......thanks for your warmly heart advance!!!
For Design RF PA,I recommend using ADS because it's performance is much better
than MWO.Ads also has a analysis called " Large signal S Parameters" for PA apps.
In microwave office you can't combine Time & Frequency domain components.for
example PA's needs matching circuits,in microwave office you can't use EM Analyzed
Matching circuits as subcircuits to compute time reponse(Transition) but in ADS you can.
The ADS Library and Design guides is excellent .ADS speed & accuracy & Capabilities
is much much more than MWO.MWO is easy to use but when you using ADS and see
it's performance i think you never used anyother software.
Definitely the latest version of MWO is much better than ADS (any version) for designing RF Power Amplifiers. You can chouse anything from Harmonic Balance, Transient Analysis, Large Signal or Small Signal (depend what models you have), Layout, etc.
Simulations using any CAD software depends by the models you use, but nowdays are a lot of factors that can make the difference between simulators.
thanks for giving me help,but still i didn't get what i am looking for....can anybody help me about PA design with MWO? any articles,examples .....thanks

If you do want to do a real comparison - and we encourage this - contact your local Agilent rep and get the latest version of ADS, and go to our web site (http://www.appwave.com) and download AWR 2006.
Hi,madengr
,Manjunatha_hv,Thanks for your help!!Manjunatha_hv,i cann't link the the links you offered before,could u pls email it to my email box :freedomboy2002@163.com? thanks! in addition,have u any other articles,ppt etc about wcdma PA design ?
could anybody tell me some tips about input network match ,output network match, input biasing network,output biasing network design in PA design? thanks
input network: most of the time the conjugate matching is good
output network: determine the optimal impedance with load-pull analysis or simple use the load-line theory and determine the optimal RL
bias: biasing the collector is simple, you need an RF choke between the collector and the supply voltage (most of the time a thin line or a meander line is good), some capacitance between the supply and the ground (SMD or plate capacitance), between the base and supply most of the time I use SMD resistor.
