which microwave design program to choose?

Hi,

we are supposed to design a bandpassfilter and a waveguide using one of the following programs: CST microwave,AWR,ADS.

which one do you suggest that we should learn? ie, which one is easiest to learn and has sufficient user interface and necessary tools?

I think CST is the best choice, but not the easiest.

I guess the best one out there is agilent genesys. I has all the features and is cheaper than the alternatives, although still pretty expensive if you are buying it on your own.

For filters you could use Dionysus **broken link removed**
For waveguides CST.

A new in-expensive microwave circuit design software (for educational, hobby, amateur, and even professional purposes), Pep, with similar format to Puff is available. Pep can run in any internet browsers installed with Java Virtual Machine independent of operating systems. The trial version and subscribed copy for 1-year license period of Pep can be available from: https://www.cosynco.com . You can have a look at that! Here we also attach our trial version for your reference (trial license expires on 1/1/2010). We will update and extend the trial period for your free test from times to times.

Its use is similar to Puff. When you unzip the pep.zip file, you can put it under some folder of your PC. Then you find there are 0_Pep_trial.html, pep.gif, Pep.jar, and a folder (directory) called pep_ckts. To start Pep, you can click on 0_Pep_trial.html, and then run password by clicking a license file under the directory called pep_ckts. After Mwboard layout window appears, you can click on any netlist (placed under the same directory with that license file). You can find brief help menu inside Pep. Later I will put the help manual here, or you can leave your request from our website https://www.cosynco.com.
